Answer: The blank can be filled correctly by "if the seeds contain the gene or allele responsible for large size of the tomatoes"
Explanation:
In plants also, characters or traits of characters are defined by genes. Different alleles produce different traits of the same character.
For example, in classic Mendelian genetics, T was the allele responsible for tall plant trait while t was the responsible for dwarf trait.
Similarly, there would be a gene(s) responsible for size of the tomatoes. In addition, seeds are the products of sexual reproduction of plants. So, they may carry genetic combination different from parent plants (due to meiosis, crossing over, independent assortment, et cetera).
So, if the seed contains the gene or allele responsible for large size of tomatoes then only they will produce same kind of tomatoes.
What do the pancreas, liver, salivary glands, and gall bladder have in common?
- They are all involved in mechanical digestion.
- They are all accessory structures.
- They all digest carbohydrates.
- They all release digesting enzymes.
Answer:
- They are all accessory structures.
Explanation:
The accessory digestive organs are the teeth, the tongue, the salivary glands, the liver, the gallbladder and the pancreas. The teeth assist in the physical breakdown of food and the tongue assists in chewing and swallowing. The other accessory digestive organs never come into direct contact with food. They produce or store secretions that pass into the gastrointestinal tract and assist in the chemical decomposition of food.
Accordingly, we can say that the correct answer to your question is "They are all accessory structures."
Terrance creates a study analyzing how broccoli consumption is related to long-term health outcomes. However, in his study, Terrance finds a zero association between eating broccoli and long-term health outcomes.True / False.
Answer:
False.
Research shows that broccoli contains vitamins C, A, B6, and E; it also contains folate and a wide range of natural compounds that contribute to the prevention of heart diseases, diabetes, and cancer, amongst others.
Explanation:
Numerous recent studies have shown that broccoli is one of the vegetables that contain a great range of nutrients that not only contribute to the prevention of the previously-mentioned diseases, but it also helps to protect bones and skin, a crucial necessity for adults, especially at an older age.
However, when performing a scientific experiment, researchers can get different results. This doesn't mean that they are wrong or that, in this case, broccoli doesn't provide any benefits. Terrance's results can be controversial but discussable.
As the majority of the research studies demonstrate beneficial effects of broccoli, he can investigate, explore, and discuss the reason behing his conclusions. For example, was this a randomized study? Were all the participants healthy or did they have diseases in which broccoli can't provide a benefit? Ages? etc.
Nonetheless, broccoli does provide health benefits that allow people to live a long, healthier life as long as the person takes care of herself/himself (eat healthy, exercise, etc) as it is not considered a drug/medicine.
A patient is dehydrated and needs fluids in his cells. Which type of IV solution will cause water to enter his cells? (DOK 1 AKS 2a) A. A hypertonic solution B. An isotonic solution C. A solution with a high salt concentration D. A hypotonic solution
Answer:
D
Explanation:
A hypotonic solution means it is less concentrated in relations to the other solution – in this case the patient’s cells. The electrolytes that balance osmotic pressure in the body are sodium, potassium, chlorides, calcium, and etcetera. The IV needs to have less electrolytes so that when the IV is injected into the patient’s blood the water can move into the cells by osmosis. Osmosis continues until the cell cytoplasm is in osmotic equilibrium with the blood. It is imporant, therefore, to have the right electrolyte balance in the IV solution otherwise the cell will over-hydrate and begin lysing – especially if the kidneys of the patient do not rid excess water fast enough.
A transition from a squirrel to a monkey is seen easily by a. the transition of paws to hands with finger nails and position of the thumb b. the transition to bipedalism c. the tranisition of tails because primates do not have tails d. none of the above
Answer:
The correct answer is b. the transition to bipedalism
Explanation:
Bipedalism is the type of movement or locomotion in which any animal use their two legs to move. A squirrel do not have ability to do transition to bipedalism but hominids like monkey have the ability to walk and run on two legs. So this transition from squirrel to a monkey can easily be seen.
Bipedalism allow monkeys to use their arms for different purpose like hanging on trees, making or using tools, fighting, using their hands to communicate each other and show their emotions. Reports shows that bipedalism require less energy for locomotion showing their advantage.
The formation of a cell plate is beginning across the middle of a cell and nuclei are re-forming at opposite ends of the cell. What kind of cell is this?
a. a plant cell undergoing cytokinesis
b. an animal cell in metaphase
c. an animal cell in telophase
d. a plant cell in metaphase
e. an animal cell undergoing cytokinesis
Answer:
a. a plant cell undergoing cytokinesis
Explanation:
Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.
At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.
The cell described is a plant cell undergoing cytokinesis. Cytokinesis is the final step in the cell cycle, where the cell physically divides. The presence of a forming cell plate and reforming nuclei are indicative of this process.
Explanation:Plant Cell Undergoing CytokinesisThe description provided fits with a plant cell undergoing cytokinesis. Cytokinesis is the physical division of a cell at the end of the cell cycle. In the process, the cell forms a structure known as a cell plate across the middle. This cell plate eventually grows and fuses with the cell wall to form two separate cells.
In animal cells, this process looks different, since animal cells lack a cell wall. Instead of a cell plate, they form a cleavage furrow which pinches the cell into two. The fact that this question mentions the formation of a cell plate suggests that we're dealing with a plant cell.
That the nuclei are reforming also indicates that the cell is in the later stages of cell division, specifically telophase or cytokinesis. Therefore, the correct answer is (a. a plant cell undergoing cytokinesis).

Maternal nondisjunction, the failure of homologous chromosomes or sister chromatids to separate properly, is associated Down syndrome and other types of aneuploidy in humans. Maternal age is associated with nondisjunction, although no age effect is seen in males. How might these findings be explained with respect to gametogenesis?
Answer and explanation:
Gametogenesis is a process in which gametes are formed from germ cells through meiosis. The genetic content of germ cells will be reduced from diploid (2n) to haploid (n). This means that the normal number of chromosomes of the species will be reduced by half.
This process in men takes place in the testicles and its purpose is to produce sperm. In the case of women, it occurs in the ovaries and the result is the production of oocytes.
Gametogenesis is performed in two successive chromosomal and cytoplasmic divisions, which are called meiosis I and meiosis II. In meiosis I the homologous pairs are joined and then separated by the mitotic bone, distributed at the poles of the cell. Then, in meiosis II, the sister chromatids of each chromosome are going to separate and are distributed in the new cells. Between both meiosis there is no division of DNA, for this reason it is that the chromosomal number is divided in half. Both meiosis include prophase, metaphase, anaphase and telophase.
As the failure to properly separate homologous chromosomes or sister chromatids is associated with Down syndrome, we can infer that it has to do with failures that occur in meiosis that will give rise to gametes.
An important difference is that gametogenesis in men occurs throughout life so they will always have "new" spermatozoa, instead, in women the gametes begin their meiosis during the prenatal stage, the oocytes will remain at rest and continue the process in each menstrual cycle from puberty (a group of oocytes is activated in each cycle and meiosis continues, being able to be fertilized or not). That is, women are born with all the oocytes they will have during their entire life. Thus, as the cycles pass the oocytes will be increasingly old and will have more risks of suffering problems during the separation of chromosomes in meiosis.
It is stated by some evolutionary scientists today that small dinosaurs eventually developed wings from jumping out of trees and then passed this acquired skill on to their descendants. this theory is based on the ideas of biologist? a) Dalton b) Darwin c) Newton d) Pasteur e) Lamarck
Answer:
e) Lamarck
Explanation:
Lamarck stated that traits could be acquired due to the use or disuse of a certain structure, for example: if giraffes were trying to reach leaves this would cause their necks to elongate and the trait would pass onto the next generation in other words organisms could change by what organisms want or need. In the 1880s, the German biologist August Weismann disproved this theory.
What is the term for the haploid form of a plant?
Answer:
I know this STRAIGHT off of my head...gametophyte.
Explanation:
Answer:
Gametophyte
Explanation:
Plants as well as other living organisms, during their reproductive life cycle, exhibit a switch between haploid state and diploid state. This process is referred to as ALTERNATION OF GENERATION. Plants are diploid organisms i.e. most of their cells contain two sets of chromosomes. This diploid state of their life cycle is called SPOROPHYTIC stage.
During reproduction, the diploid sporophyte of the plant undergoes meiosis i.e. reduction division to produce haploid spores. These haploid spores germinates and undergoes series of mitotic divisions to form the haploid GAMETOPHYTE of the plant, which is the haploid form of the plant. The gametophye of the plant produces haploid gametes (sperm and egg) which combines in a process called FERTILIZATION to produce a diploid ZYGOTE that grows via mitosis into the diploid SPOROPHYTIC structure of the plant.
The cycle starts again from the beginning, hence, it is called an ALTERNATION OF GENERATIONS.

One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.
Which of the following, if true, most strengthens the argument?
(A) Diallyl sulfide is also found in onions but at concentrations lower than in garlic.
(B) The mosquito population of the region as a whole was significantly smaller during the year in which the flooding took place than it had been in previous years.
(C) By the end of the summer, most of the garlic plants in the flooded fields had been killed by waterborne fungi.
(D) Many insect species not repelled by diallyl sulfide were found in the flooded garlic fields throughout the summer.
(E) Mosquitoes are known to be susceptible to toxins in plants other than garlic, such as marigolds.
Answer:
(D) Many insect species not repelled by diallyl sulfide were found in the flooded garlic fields throughout the summer.
Explanation:
Mosquitoes were not found in the ideal breeding environment provided by the standing water in flooded fields. The fields were planted with garlic plants which are rich in diallyl sulfide and it is known to repel mosquitoes. Hence, mosquitoes were not able to propagate in the garlic fields.
A statement that can strengthen this argument is that insect species which are not repelled by diallyl sulfide were found in the flooded waters. If these insects were also not present then it could have been said that some other factor apart from diallyl sulfide was operating to halt their breeding. Other insect species were probably still present in fields because they are not repelled by diallyl sulfide.

Many crustaceans (for example, lobsters, shrimp, and crayfish) use their tails to swim, but crabs have reduced tails that curl under their shells and are not used in swimming. This is an example of _____.a. natural selectionb. an adaptationc. a homologous structured. a vestigial trait
Answer:
a vestigial trait
Explanation:
Vestigial trait is a characteristic that is present in an organism but not used for the intended purpose. For example: vestigial organs. These structures are in their rudimentary form and almost degenerated because they are not required anymore by the organism.
Many crustaceans use their tails to swim and hence have functional fully formed tails. However crabs usually walk on ocean beds. Crabs that do swim have modified rear legs. Hence, there is no requirement of a functional tail in crabs making it a vestigial trait. As a result, the tail is reduced and curled under their shells.

Fenestrated capillaries ________.
A. are not common in endocrine organs and in areas where capillary absorption is an important function
B. are not more permeable than continuous capillaries
C. do not occur in the glomerular capillaries of the kidneys
D. are not found in the brain
Answer:
D. are not found in the brain
Explanation:
Capillaries are the smallest blood vessels. Their wall is made of a single layer of endothelial cells. Continuous capillaries have uninterrupted lining of endothelial cells. Only small molecules like water molecules and ions can pass through them. Fenestrated capillaries on the other hand have 60-80 nm diameter pores in endothelial cells. Some larger molecules like certain types of proteins can diffuse through them.
They are found in tissues which are engaged in extensive molecular exchange with blood like endocrine glands, kidney and small intestine because they are more permeable than continuous capillaries. They are not found in brain because molecular exchange needs to be highly regulated and restricted in brain. Brain has continuous capillaries which form the blood brain barrier.

Lima, Peru, is a city on the shore of the eastern Pacific. During a La Niña, you would expect the weather to be A. Warmer, drier than normal B. Warmer, wetter than normal C. Cooler, drier than normal D. Cooler, wetter than normal
Answer:
C. Cooler, drier than normal.
Explanation:
La Niña is a climate phenomenon, the colder counterpart of El Niño, that is characterized by the production or appearance of unusual colder temperatures in the regions of the Pacific Ocean, leading to the weakening of the maritime and continental anticyclones, which are areas of low cloudiness and atmospheric pressures that lessen the storms. It provokes
According to NASA, the atmosphere cools because of the low sea surface temperature and causes less water to evaporate. This results in a cooler, denser, and drier air in the region of Peru on the shore of the eastern Pacific Ocean.
Final answer:
During a La Niña event in Lima, Peru, the weather is cooler and drier than normal due to the cooling effects of the eastern Pacific Ocean and stronger trade winds.
Explanation:
In Lima, Peru, during a La Niña event, you would expect the weather to be cooler, drier than normal. La Niña is characterized by cooler than normal ocean temperatures in the eastern Pacific, particularly off the coast of Peru, which results from stronger trade winds. These conditions lead to reduced evaporation and less rainfall, making the coastal areas of Peru drier. In contrast, El Niño conditions, which involve warmer ocean temperatures, lead to wetter weather due to increased evaporation and rainfall. As such, a La Niña typically has the opposite effect, thus the correct answer to the student's question is C. Cooler, drier than normal.
Methanol poisoning occurs when the body converts a large amount of methanol to harmful chemicals that attack the optic nerves, leading to acute blindness. Ethanol is the antidote for methanol poisoning because ethanol is preferentially processed by the body. Ethanol is most likely to be a(n):A. allosteric inhibitor.B. competitive inhibitor.C. noncompetitive inhibitor.D. irreversible inhibitor.
Answer:
Ethanol is most likely to be a (B), competitive inhibitor.
Explanation:
The poisoing occurs because of the harmful metabolites produced by the alcohol dehydrogenases, enzymes in charge of breaking down alcohol.
Hence, the most likely strategy of an antidote is to compete for the active site of the enzyme and prevent the methanol convertion to harmful chemicals.
Ethanol does not produce these metabolites and it is preferentially proccessed by the body, so it is a competitive inhibitor, competing for the active site.

not sure about 2 but, 1 is D. and 3 is A., while 4 is D.
Explanation:
This response outlines general observations about enzyme activity, macromolecule function, protein structure, and digestive enzymes based on given options. Specific answers require the actual graphs and pictures. Key points include enzyme functioning at optimal temperatures and pH levels, functions of macromolecules determined by their structure, protein structures influenced by amino acid combinations, and pepsin being the most likely active enzyme in the stomach's acidic environment.
Explanation:Without the actual graphs and pictures, exact answers can't be provided. Nonetheless, I'll attempt to provide some general observations:
Enzymes are known to function optimally at specific temperatures and pH levels. Their activity can be represented in graphs, which would show peaks at these optimal points. If we assume option D to be true, it suggests that the enzyme has its maximum activity at a temperature of approximately 37° C and a pH range of 6 to 8.
Macromolecules have different functions based on their structure. In general, option A might point to carbohydrates, option B to nucleic acids, option C to proteins (specifically hemoglobin), and option D to a complex carbohydrate like cellulose. An accurate answer would require the actual image.
Proteins indeed have various structures necessary for their wide range of functions. Structures are determined by the different combinations of the 20 amino acids - which supports argument B.
Lastly, the stomach has an acidic environment with a low pH value. Pepsin, a digestive enzyme that works optimally at low pH, might be the most active in the stomach. Hence, the answer might be option C.

Recall Pasteur's experiment on spontaneous generation. If he had just warmed the nutrient-rich broth, rather than boiled it, what would have been the likely outcome of his experiment? Cells would ________.a. have appeared in the swan-neck but not the straight-neck flask
b. not have appeared in either flask
c. have appeared in both flasks
d. have appeared in the straight-neck but not the swan-neck flask
Answer:
C. Have appeared in both flasks.
Explanation:
Cells would have appeared in the straight-neck and in the swan-neck flask because the process of boiling water is essential to eliminate the possible microorganisms present in the broth before the experiment.
If only the microbes that were previously in the broth were heated, they would not die and keep playing
Final answer:
If Pasteur had only warmed the broth instead of boiling it, cells would c) have likely appeared in both the swan-neck and the straight-neck flasks, indicating contamination since warming may not sterilize the broth effectively.
Explanation:
Recall Pasteur's experiment on spontaneous generation. If he had just warmed the nutrient-rich broth rather than boiled it, the likely outcome of his experiment would be that cells would c) have appeared in both flasks. This is because simply warming the broth may not have been sufficient to sterilize it and kill off existing microorganisms, which would still lead to contamination and growth in both the swan-neck and the straight-neck flask. Louis Pasteur's experiment proved that microbial life can only arise from existing microorganisms and not spontaneously from non-living matter. His design involved boiling the broth to sterilize it and prevent microorganisms from growing, while still allowing air to reach the broth through the swan-neck design, which kept airborne microbes from entering.
ason and Alex are biologically unrelated adolescents who were adopted as infants and raised together. For which of the following are Jason and Alex least likely to resemble each other any more than they resemble a genetically unrelated adolescent from another home in their neighborhood?
A) extraversion
B) religious beliefs
C) table manners
D) political attitudes
Answer:
The correct answer is A) extraversion
Explanation:
Extraversion if one trait out of five traits that makes a person's personality. Extrovert people are more talkative, cheerful, energetic and social. They love to talk and make friends. They also have more leadership quality that introvert people.
An extravert person has sub traits like friendliness, assertiveness, excitement-seeking, cheerfulness, activity level, and gregariousness.
So extraversion is related to personality and all the members in the home have different personality like some may be extravert and some are introvert (conservative in nature).
As Jason and Alex are raised together so their religious beliefs, table manners, and political attitudes might be the same but they both might not have the same personality and extraversion trait.
Paul Templet describes the process of eutrophication in the Gulf of Mexico. According to Templet, which of the following initiates the process?
a. Phytoplankton feed on nutrients, which creates plankton blooms.
b. Decaying marine organisms consume dissolved oxygen in the water.
c. Farm run-off carrying nutrients from nitrogen fertilizer washes to the ocean.
d. Plankton blooms cause a decrease in dissolved oxygen in the water.
Answer:
Farm run-off carrying nutrients from nitrogen fertilizer washes to the ocean.
Explanation:
When any water body becomes heavily enriched with minerals and nutrients such that it induces excessive growth of algae on the water body then such a process is known as eutrophication. The Gulf of Mexico is facing the problem of eutrophication due to the farm practices that are contributing to the formation of a dead zone in the Gulf. Farm run-off that carries nitrogen fertilizers into the ocean contributes to the excess of nutrients into the water body and cause depletion of dissolved oxygen in the water body.
