Answer:
possible gamete combinations are
BB,bb,GG
Final answer:
The organism with genotype BbGG can produce two types of gamete combinations: BG and bG, because the B allele is heterozygous and the G allele is homozygous.
Explanation:
The organism's genotype is BbGG. When organisms produce gametes, which are cells used for sexual reproduction (like sperm and eggs), each gamete gets one set of chromosomes. This organism has two different alleles at the first gene locus (B and b), but the same allele at the second gene locus (G).
During gamete formation, alleles for different genes separate so that each gamete only gets one allele for each gene. In this case, the organism can produce gametes with combinations of BG and bG, since the genotype for the second gene locus is homozygous (GG), meaning it will always contribute a G allele.
The organism has a heterozygous genotype for the B gene locus and a homozygous genotype for the G gene locus, resulting in two possible gamete combinations: BG and bG.
the plasma membrane (cell membrane) is made up of a(n)
The plasma membrane is composed of proteins, lipids, carbohydrates and other substances where the various components make it a selectively permeable barrier.
What is Plasma Membrane?Plasma membrane also known as cell membrane is defined as the biological membrane that separates and protects the interior of all cells from the external environment. It is a thin membrane that surrounds every living cell, separating it from its surrounding external environment.
The plasma membrane is called a selectively permeable membrane because it regulates the movement of substances into and out of the cell, meaning that the plasma membrane allows some materials to pass through it while at the same time it allows other materials to pass through it.
Thus, the plasma membrane is composed of proteins, lipids, carbohydrates and other substances where the various components make it a selectively permeable barrier.

explain Why DNA must be copied during interphase before cell division can occur?
Answer:
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Which sentence has a shift in verb tense?
The barrier will drop down every time that a train approaches the crossing.
If anyone knows the answer, she does.
As I came in the front door, Eddie is going out the back door.
A row of ants had filed up the chair leg and was about to consume our lunch.
help pls
Answer: As I came in the front door, Eddie is going out the back door.
Explanation:
"The correct answer is: As I came in the front door, Eddie is going out the back door. The sentence with the shift in verb tense is As I came in the front door, Eddie is going out the back door.
The sentence As I came in the front door, Eddie is going out the back door. exhibits a shift in verb tense. The first clause As I came in the front door uses the past tense came, which is appropriate for an action that was completed in the past. However, the second clause Eddie is going out the back door uses the present progressive tense is going, which does not align with the past tense of the first clause. To maintain consistency in verb tense, the second clause should also be in the past tense, such as Eddie was going out the back door.
Let's analyze the other sentences for verb tense consistency:
1. The barrier will drop down every time that a train approaches the crossing.
- This sentence uses the future tense will drop to describe an action that will happen repeatedly in the future when a train approaches. There is no shift in tense within this sentence.
2. If anyone knows the answer, she does.
- The verb tense in this sentence is consistent. The conditional clause If anyone knows the answer is in the present tense, and the main clause she does also uses the present tense.
3. A row of ants had filed up the chair leg and was about to consume our lunch.
- This sentence uses the past perfect tense had filed to describe an action completed before another past action, and the past continuous tense was about to consume to describe an ongoing action in the past. The verb tenses are consistent within the context of the sentence, as both actions are situated in the past, with one occurring before the other.
Therefore, the sentence with the shift in verb tense is As I came in the front door, Eddie is going out the back door."

why do cells use more than one photosynthetic pigment?
Answer:
Plant cells use more than one pigment because more than one pigment or multiple pigments absorb different wavelength of light from sun and this difference absorption spectra is very much important during photosynthesis.
Explanation:
Plant cells use multiple pigments because some pigments also called principle pigments function within the reaction center where some accessory pigments are also present such as carotene,phycobillin, xanthophyll which act as antena complex that play an important in light absorption.
The presence of different pigment provides different coloration of fruits,leaves.For example presence of carotene gives orange,yellow coloration to carrot,tomato.
17. Name 3 scientists that helped to discover the structure of DNA.
Answer: James Watson, Francis Crick, and Rosalind Franklin (these are just 3)
Explanation:
In 1952, Watson and Crick took the first X-ray picture of DNA. Created by Rosalind Franklin, she used a technique called X-ray Crystallography, that is how they discovered the helical structure of DNA
Francis Crick, James Watson, and Rosalind Franklin played crucial roles in discovering the DNA's structure. Watson and Crick proposed the double helix model, but Franklin's X-ray diffraction data were essential to confirm that model.
Three scientists that were instrumental in discovering the structure of DNA were Francis Crick, James Watson, and Rosalind Franklin. Crick and Watson, working at the University of Cambridge, are often given the most credit for describing the molecular structure of DNA as a double helix. However, Rosalind Franklin's contributions, particularly her X-ray diffraction pattern of DNA, were crucial. This pattern provided key insights that supported the double helix model. Thus, while Watson and Crick were the ones to publish the proposed structure of DNA, it was Franklin's work that was essential in validating their model.
Observing the size of a herd of elephants that are all the same species would be an observation at the __________ level.
A. ocommunity
B. ecosystem
C. population
D. individual
Final answer:
Observing the size of a herd of elephants that are all the same species would be an observation at the population level, as a population includes all individuals of a species within a specific area.
Explanation:
Observing the size of a herd of elephants that are all the same species would be an observation at the population level. A population is defined as all the individuals of a species living within a specific area. Therefore, when the observation focuses on a single species and its size within a particular area, this concerns population ecology. In contrast, a community would consist of multiple different species interacting in an area, an ecosystem includes both living and non-living components, and an individual would refer to a single organism.

What does it mean when it says that aerobic respiration occurs in the cytoplasm “TO” the mitochondria???
Answer:
Kerb cycle
Explanation:
The result from mitochondria is ATP, that acts as a currency of the energy in the cell. In the cytoplasm of mitochondria kerb cycle occurs. In this process it has several other process, once it uses acetate and water to give NADH from NAD+ and gives carbon dioxide as waste. The NADH formed is fed by oxidative phosphorylation or electron transport. The outcome of these processes is oxidation of nutrients to give chemical energy in ATP form.
Light-independent reactions occur in the stroma, or the thick fluid located between the grana, of chloroplasts. What is the main purpose of photosynthetic light-independent (dark) reactions?
Answer:
Carbohydrate synthesis
Explanation:
In light-independent reactions, sunlight is not used to build up carbohydrate molecules. The light-independent reaction is also called the Calvin Cycle. Light independent reactions take place in the chloroplast. Carbon dioxide diffuses from stomata into the stroma of chloroplast where fixation, reduction and regeneration takes place by using the energy of ATP and NADPH to make glucose and carbohydrate molecules.

eggs are used in alot of baking goods eaten over thanksgiving. eggs only have one set of chromosomes. list three vocabulary words or terms that describe the number of chromosomes found in an egg.
The 3 vocabulary words or terms that describe the number of chromosomes found in an egg are are haploid, diploid and triploid.
Explanation:
Egg is a very common ingredient which is used a lot in baking goods like making of cakes and cookies. The egg has only one set of chromosomes. There are few terms which are used for describing the number of chromosomes found in egg. The term haploid means egg having single set of unpaired chromosomes.
The term diploid means having two sets of complete chromosomes obtaining from parents’ cell. The term triploid means having an extra set of unpaired chromosomes. The case of triploid is very rare and uncommon. It happens at very rare case. It is also not stable as diploid.
Final answer:
An egg has a single set of chromosomes and is described as haploid (1n). Vocabulary words related to this include 'haploid,' '1n,' and 'gamete.'
Explanation:
The number of chromosomes found in an egg can be described using a few key terms. An egg is a gamete, which is a type of cell involved in sexual reproduction that is haploid, meaning it contains a single set of chromosomes. Three vocabulary words that describe the chromosomal number in an egg are:
Haploid: Describes a cell that has half the number of chromosomes as the diploid cells of the organism. In humans, a haploid cell has 23 chromosomes.1n: This is the notation used to signify the haploid number of chromosomes in gametes, where 'n' is the number of chromosomes in a single set.gamete: Refers to the mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.When a sperm (haploid) and an egg (haploid) combine, they form a zygote, which is diploid (2n), containing two sets of chromosomes.
ATPase changes _____________to________________
ATPase changes ATP to ADP.
Explanation:

They are F-ATPase, V-ATPases, A-ATPases, P-ATPases and E-ATPases are the five types. F-ATPases is found in mitochondria and chloroplasts while V-ATPase is found in eukaryotic vacuoles.
Andy's teacher asked him to come up to the front of the class to demonstrate work. Which of the following could Andy do in the classroom to demonstrate work? A. Andy pushes a desk across the floor. B. Andy sits in his chair, doing nothing. C. Andy pushes against a desk, and it doesn't move. D. Andy holds a book.
Answer:
Andy pushes a desk across the floor.
Explanation:
An example of work in the classroom would be if Andy pushes a desk across the floor.
Work is done by transferring energy to an object (from Andy to the desk) by applying a force (the push), which makes the object move in the direction of the force.
If Andy sits in his chair, or holds his book, he is not applying a force that moves any object. Also, if Andy pushes his desk, but it doesn't move, work is not being done (since the object must move for work to be done).

What explains the sequence of energy transformation during photosynthesis?
Answer:
Light energy converts into chemical energy.
Explanation:
Photosynthesis occurs in the chlorophyll-containing part of the plant. During this process, light energy from sunlight is taken by the chlorophyll pigment, which is present in chloroplast. This captured light energy takes water and carbon dioxide to produces carbohydrates as a source of food. These carbohydrates then converted into ATP molecules. These ATP molecules are stored in the form of chemical energy.
The most important factors in determining the rate of weathering are
A) animal actions and oxygen
B) abrasion and acids from plant roots
C) carbon dioxide and acid rain
D) rock type and climate
Answer:
The answer is D
Explanation:
Answer:
D) rock type and climate
Explanation:
Weathering is the process of transformation of rocks by disintegration (physical) or decomposition (chemical) of their structures, giving rise to sediments and interfering in sedimentary processes, such as erosion, diagenesis and pedogenesis (formation of soils). Although weathering has several factors that may or may not accelerate the decomposition of rock structures, the most important factors in this are the climate and the type of rock. these factors are the most important because they act constantly and uninterruptedly on the rock.
Explain why nitrate fertilizers may not be suitable for application in soils with low redox potential
Answer:
Nitrate fertilizers may not be suitable for application in soils with low redox potential as there will be no required reduction takes place. Crops with excess nitrogen will affect the health of the consumer.
Explanation:
Redox potential (Reduction/Oxidation potential) is tendency of a chemical species to gain electrons from an electrode or loss electrons to electrode as a result of Oxidation or Reduction. Nitrogen is an important element for 'plant growth and development', but due to pollution, high nitrate concentration accumulate in the edible part of the food product and particularly when 'excess nitrogen fertilizer' has been applied. When the redox potential is very low then there is no any chance for nitrogen to get diluted which results in the excess of nitrogen content and so nitrate fertilizers may not be suitable for application in soil with low redox potential. Selection of nitratae fertilizer compatetive to the soil is very important.Final answer:
Nitrate fertilizers may not be suitable for soils with low redox potential due to denitrification, which converts nitrate into dinitrogen gas. This process leads to a loss of nitrogen from the soil and can release greenhouse gases. Waterlogged soils and excessive fertilizer use can contribute to low redox potential.
Explanation:
Nitrate fertilizers may not be suitable for application in soils with low redox potential because of the process of denitrification. Denitrifying bacteria use nitrate as an electron acceptor and convert it into dinitrogen gas, which plants cannot utilize. This leads to a loss of nitrogen from the soil, which is an essential nutrient for plants. Additionally, the conversion of nitrate to dinitrogen gas can result in the release of [tex]N_2O[/tex] greenhouse gas. Waterlogged soils and excessive use of fertilizers can contribute to low redox potential, making nitrate fertilizers less effective in these conditions.

In order to subtract fractions we need to take a least common denominator of 5 and 3. This denominator must be the least common multiple of both numbers.
Multiples of 3→ 3,9,12,15,....
Multiples of 5→ 5,10,15,......
From the multiples we find out the least common number to be [tex]=15[/tex]
So 15 will be the least common denominator.
In order to make the denominator =15 for both fractions, we need to multiply the same numbers to numerator and denominator of each fraction.
⇒ [tex]\frac{2\times 3}{5\times 3}-\frac{1\times 5}{3\times 5}[/tex]
⇒ [tex]\frac{6}{15}-\frac{5}{15}[/tex]
Then we can subtract the numerators keeping the denominator same.
⇒ [tex]\frac{6-5}{15}[/tex]
⇒[tex]\frac{1}{15}[/tex]
