Measure the amount of energy in the phytoplankton and the amount of light entering the aquarium. Then measure the amount of energy in the phytoplankton after exposure to the light and determine the difference.
Explanation:
Phytoplanktons like most of the plants use chlorophyll, sunlight and carbon di-oxide for photosynthesis but it depends on other organisms to consume extra energy as they are unable to gain enough energy from their consumption of light. This differs among the different species of planktons.
It can be observed in an aquarium that a phytoplankton is gaining less energy than the energy they have absorbed by the light and this can be done by measuring the energy before and after the photosynthesis.

What is the relationship between proto-oncogenes and oncogenes?
Answer:
Oncogenes result from a mutation in proto-oncogenes.
Explanation:
Protooncogenes control the growth and division of cells.The proteins encoded by proto-oncogenes include growth factors, growth factor receptors, transcription factors and signal transducers.They contribute to the transformation process by driving cell proliferation or reducing sensitivity to cell death.Several types of genetic and epigenetic changes convert these proto-oncogenes to oncogenes.Oncogenes arise due to the changes that increases the expression of proto-oncogenes .Oncogenes are one of the causes of cancers.A proto-oncogenes can turn into oncogene by following ways:
A point mutation such as deletion, insertion and substitution in the proto-oncogene can lead to formation of oncogenes. Chromosomal translocation may result in activation of proto-oncogene as seen in Burkitt's lymphoma.Insertion of a mobile genetic material such as retrovirus changes the gene expression, but leaves their coding sequence intact. Activation of proto-oncogene can also occur from reduplication and amplification of DNA sequence.Final answer:
Proto-oncogenes are positive cell-cycle regulators. When mutated, they can become oncogenes and cause cancer. For example, the oncogene myc is involved in Burkett's Lymphoma.
Explanation:
Proto-oncogenes are positive cell-cycle regulators. When mutated, proto-oncogenes can become oncogenes and cause cancer. Overexpression of the oncogene can lead to uncontrolled cell growth. This is because oncogenes can alter transcriptional activity, stability, or protein translation of another gene that directly or indirectly controls cell growth. An example of an oncogene involved in cancer is a protein called myc. Myc is a transcription factor that is aberrantly activated in Burkett's Lymphoma, a cancer of the lymph system. Overexpression of myc transforms normal B cells into cancerous cells that continue to grow uncontrollably. High B-cell numbers can result in tumors that can interfere with normal bodily function. Patients with Burkett's lymphoma can develop tumors on their jaw or in their mouth that interfere with the ability to eat.
How do lichens contribute to primary succession? Lichens begin to break down rock to form soil. Lichens decompose organic matter from animals and plants. Lichens are nitrogen-fixing bacteria. Lichens convert carbohydrates into fossil fuels.
Lichens contribute to primary succession by breaking down rocks, forming soil, and adding organic material. They are a mutualistic association between a fungus and a photosynthetic partner, with each partner providing necessary components for survival and growth. Some cyanobacteria in lichens additionally fix nitrogen.
Explanation:Lichens contribute to primary succession by colonizing rock surfaces in otherwise lifeless environments, breaking down rocks to form soil, and adding organic material to further contribute to soil formation. Lichens are a mutualistic association between a fungus and a photosynthetic partner, such as an alga or a cyanobacterium. The fungus supplies minerals and protection, while the photosynthetic partner provides carbon and energy. Some cyanobacteria in lichens also fix nitrogen from the atmosphere, contributing nitrogenous compounds to the association.

#SPJ11
Lichens are pivotal in primary succession, colonizing barren rock surfaces and initiating soil formation through the breakdown of rock and nitrogen fixation.
Lichens contribute to primary succession by acting as pioneer species that colonize lifeless rock surfaces, such as those left after glacial recession or volcanic activity. Through a symbiotic relationship between a fungus and either an alga or a cyanobacterium, lichens are formidable survivors that can thrive without soil. They produce acids that help break down rocks to form the first layers of soil. Moreover, certain types of lichens are capable of nitrogen fixation, which adds essential nutrients to the forming soil, supporting future growth of plant life.

A) mice are recaptured in the same location using the same trapping methods
B) mice deliberately return because the traps contain food
C) biologist waits a long time before resampling the population
D) mice are territorial
Answer:
I think the answer is A
Explanation:
Since the question states that they want to determine the population of the desert mice. You get the direct answer from just using context clues. Since population means one species in a certain area, it means that this method will work if the mice stay in the same area.
As a first step in the proposal, the investigator(Wouldbe Fiancé) needs to make many copies of DNA of known sequence. How would they do that? A)Carry out DNA cloning of the desired sequence into a plasmid vector and then put that into bacteria and wait for the bacteria to copy the gene every time the cells divide. B)Wait for helicase to unzip the genes. C)Make a long sequence of adenines so they could get paired with U. D)Alterthe reading frame of the mRNA.
Answer:
The correct option is A) Carry out DNA cloning of the desired sequence into a plasmid vector and then put that into bacteria and wait for the bacteria to copy the gene every time the cells divide.
Explanation:
The DNA can be easily cloned by the help of vectors like plasmids. Plasmids can be described as an extra-chromosomal ring which is present in bacteria. The plasmid has many multiple cloning sites where the desired DNA can be incorporated. the plasmid with the foreign DNA is then incorporated back into a bacterial cell. As bacterial cells like E.coli divide in a short period of time, many copied of our DNA could be obtained whenever the bacterial cell replicates.
A small town in the piney woods of East Texas has a soccer field composed of native grasses. The soccer field is mowed once a week.
What effect does continual mowing have on the ecology of the field?
A)
Mowing increases the likelihood of nonnative species displacing native species.
B)
Mowing increases the number of species found in the field.
C)
Mowing causes different types of communities to form across the field.
D)
Mowing maintains a low species diversity by inhibiting succession.
Explanation:
D) Mowing maintains a low species diversity by inhibiting succession.
Mowing reduces the chances of growth of a new species within the community that may add to its complexity.
Succession involves small scale changes within a community that occur repeatedly over the life of that community. Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
colonizing species exploiting uninhabited areas (Primary succession) becoming a habitable and increasingly complex community there is increased diversity of organisms (Secondary)Further Explanation:
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

Hence, the correct option is a.
where does translation take place in the cell
Answer:
cytoplasm that is where the translation take place
Final answer:
Translation, the process of protein synthesis, occurs in the cytoplasm of cells where ribosomes are located. In eukaryotic cells, this process is separated from transcription by the nuclear membrane, requiring mRNA transport from the nucleus to the cytoplasm.
Explanation:
In eukaryotic cells, translation is the process by which ribosomes synthesize proteins using the genetic information carried by messenger RNA (mRNA). This process takes place in the cytoplasm of the cell, where ribosomes are found. After RNA transcription occurs in the nucleus, the mRNA is transported to the cytoplasm. Translation involves reading the genetic code on the mRNA to produce a specific sequence of amino acids, thus forming a protein.
It is important to note that in prokaryotic cells, translation can begin before transcription has finished because both processes occur in the cytoplasm. However, in eukaryotic cells, the nuclear membrane physically separates the transcription process in the nucleus from the translation process in the cytoplasm. Therefore, translation in eukaryotic cells can only begin after the mRNA has been fully processed and transported out of the nucleus to the cytoplasmic ribosomes.
What are the structures of the brain that increase surface area called?
Answer:
gyri (ridges) and sulci (furrows)
Explanation:
Gyri are ridges, Sulci are grooves. Sulci encircle each gyrus, increasing the cerebral cortex's surface area and dividing the brain. By expanding brain size, more neurons can fit in the cortex, boosting its processing power.
What are gyri an sulci?Gyri is the name given to the ridges, and Sulci is the name given to the grooves. Each gyrus has sulci surrounding it, and these sulci work together with the gyri to increase the surface area of the cerebral cortex and produce divisions in the brain. Increasing the surface area of the brain allows for a greater number of neurons to be packed into the cortex, which in turn increases the processing power of the cortex.
The folding of the cortex, the region of our brain that is responsible for higher cognitive processes including memory, language, and consciousness, results in these morphological traits.

competition for food and survival on the mainland provided stabilizing selection.
Explanation:
Based on the information provided within the question it seems that the most plausible biological explanation is that the amount of competition for food and survival on the mainland provided stabilizing selection. This was most likely not seen in the islands from which they came and therefore provided the ideal conditions in order for the Finches to diversify rapidly into a multitude of new forms,
Imagine you are performing a cross involving seed color in garden pea plants. What F1 offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green.
A. 100 percent yellow-green seeds
B. 100 percent yellow seeds
C. 50 percent yellow, 50 percent green seeds
D. 25 percent green, 75 percent yellow seeds
Answer:
B. 100 percent yellow seeds
Explanation:
When a gene has two alleles and one allele is dominant over the other, the dominant allele is expressed in the heterozygous state and the expression of the recessive allele is masked. According to the given information, the allele for yellow seed color is dominant over the allele for the green seed color.
Let's assume that the allele "Y" gives yellow color to the seeds while the allele "y" is responsible for green seed color. A cross between two pure breeding yellow seeded (YY) and green seeded (yy) plants would produce all the yellow seeded progeny with genotype "Yy".
YY (Yellow) x yy (green) = Yy (yellow)
Final answer:
When crossing true-breeding parents with green and yellow seeds, the F1 offspring would be 100 percent yellow phenotype.
Explanation:
When crossing true-breeding parents with green and yellow seeds, where yellow is dominant, the F1 offspring would be heterozygous for seed color, resulting in a 100 percent yellow phenotype. This means that all F1 offspring would have yellow seeds, even though one parent has green seeds.

Which of the following animals indicated in the Antarctica Food Web folder utilizes the Crabeater Seal as a source of food? a. Humpback Whale b. Sharks c. Krill d. Leopard Seal e. Squid
The animal that uses the Crabeater Seal as a food source in the Antarctica Food Web is the Leopard Seal. Humpback whales, sharks, krill, and squid do not feed on crabeater seals. As for the effects of melting sea ice in Alaska, polar bears would be the most affected.
The correct answer to the question of which animal in the Antarctica Food Web utilizes the Crabeater Seal as a source of food is d. Leopard Seal. Leopard seals are top predators in the Antarctic ecosystem, known to prey on other marine mammals, including the crabeater seal. This information helps us understand the dynamics of Antarctic food webs and the importance of each species in maintaining ecological balance.
Humpback whales primarily feed on krill and small fish, not on crabeater seals.
Sharks are not typically part of the Antarctic food web where crabeater seals live.
Krill are a primary food source for many animals, but they do not consume crabeater seals.
Squid also do not feed on crabeater seals, as they have different dietary preferences.
Concerning the Arctic food web and the impact of sea ice melting in Alaska, polar bears would be most affected (option b) because they rely on sea ice to hunt for seals, their primary food source.
Movement of the chromosomes during anaphase would be most affected by a drug that prevents mitosis and cell division. What is this drug?
Answer:
Colchicine
Explanation:
Colchicine is an alkaloid derived from the autumn crocus (Colchicum autumnale).
The effect of colchicine, which inhibits microtubule polymerization and thus assembly of the mitotic spindle, demonstrates the presence of another checkpoint in the cell cycle. When colchicine is added to cultured cells, the cells enter mitosis and arrest with condensed chromosomes. With increasing time, a large fraction of the cells in a culture become arrested, thus permitting determination of the size, shape, and number of mitotic chromosomes — that is, the karyotype — in multiple cells. A checkpoint control somehow senses when the mitotic spindle has not assembled properly and prevents activation of the APC polyubiquitination system that normally leads to degradation of the anaphase inhibitor, required for onset of anaphase, and later to the degradation of mitotic cyclins, required for the exit from mitosis. As a result, MPF activity remains high, chromosomes remain condensed, and the nuclear envelope does not re-form.
Bees can see colors we cannot see, and they can detect minute amounts of chemicals we cannot sense. Unlike many insects, bees cannot hear very well. A biologist would probably give which of the following as the ultimate explanation for their poor hearing?a.) If a bee could hear, its highly programmed brain would be overwhelmed with information.b.) If bees could hear, the noise of the hive would be overstimulating.c.) This is an example of altruism.d.) Bees are too small to have functional ears.e.) Hearing may not contribute much to a bee's reproductive success.
Answer: The answer would likely be E.
Explanation:
The biologist would likely explain this concept from the viewpoint of evolution. As hearing does not contribute to the bee's reproductive success, enhanced hearing traits in bees were not selected for and hence bees' hearing ability was not an adaptation that enhanced its reproductive success and bees cannot hear very well.

Sometimes drugs, such as phenobarbital, are given in a higher dose as a loading dose and then tapered back to a maintenance dose. This helps the drug to accumulate to a therapeutic level in the body until the concentration plateaus. When this occurs, the drug has reached which of the following?
a.Nadir
b.Steady state
c.Half-life
d.Bioavailability
Answer:
b.Steady state
Explanation:
When a drug is in a steady state is usually defined as the time during which the drug remains stable when administered repeatedly or continuously (IV infusion) - this is the state where the rate of the drug entering the systemic circulation or drug administration equals to its rate of elimination out of the system. In the case where a drug is administered multiple times in fixed intervals the plasma concentration increases till it plateaus. This administration pattern will result in a steady-state concentration which is intended to be within the therapeutic window
