Which of the following is a product of cellular respiration?
Carbon dioxide
Oxygen
Carbon monoxide
Nitrogen
Answer:
it Carbon dioxide and water but Carbon Dioxide was the only one here
Explanation:
The one that is a product of cellular respiration is carbon dioxide. The correct option is A.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the appearance of an inorganic electron acceptor such as oxygen to yield huge amounts of energy, which drives the bulk production of ATP.
In plants, photoautotrophic processes are used to obtain the glucose required for cellular respiration. This means that plants can use the light energy they receive from the sun to produce glucose and oxygen.
ATP is the primary product of cellular respiration; waste products include carbon dioxide and water.
All through cellular respiration, one sugar molecule is converted into 38 ATP molecules. The electron transport system actually creates 34 molecules of ATP out of a total of 38 molecules.
Thus, the correct option is A.

What is the end result of crossing-over during the first stage of meiosis?
-the paternal DNA only is copied onto the chromatids
-the chromatids are identical to each other
-the chromatids contain the maternal DNA only
-the chromatids become non-sister (non-identical) chromatids
Answer:
The chromatids contain the maternal DNA only.
Explanation:
They must contain half the original number of chromosomes. It must contain only one chromosome in place of each homologous pair of chromosomes, so it is endowed with either the maternal or the paternal copy of each gene but not both.

If you crossed two plants from the F2 generation, what procedure would you follow to determine the genotypes of the next generation?
Answer:
You would use a test cross to determine the next generation
Explanation:
If you crossed two plants from the F2 generation, test cross procedure you should follow to determine the genotypes of the next generation.
What is a test cross?Another important tool created by Gregor Mendel is the test cross. A test cross is a genetic experiment that involves crossing a homozygous recessive organism having a dominant phenotype with an unidentified genotype (and phenotype).
A test cross is a tool for investigating an organism's genetic makeup. The test cross was initially employed as an experimental mating test to identify the genotype's allele composition.
Therefore, to determine the genotypes, the test cross gets its name from the fact that it can tell whether a person has a homozygous dominant or heterozygous dominant trait.

Starch is found in foods such as peas, corn, and potatoes. For the body to receive energy from starch, it is broken down into smaller units. A mutation occurs in the gene that codes for a protein that breaks down starch.In which case will the mutation be harmful?
This mutation would be harmful for the body because, when not able to break down the starch and use it for energy, the body will begin to have starch buildup and not be able to do anything with it. It would continue to build up and do some serious damage everytime someone who has this mutated gene eats food rich in starch.

Nitrogen and phosphorus are referred to as macronutrients because ________. A. they are larger than other nutrients needed by plants B. they are needed by large organisms C. they are required in large amounts for organisms to survive D. they are needed to manufacture large biomolecules E. their cycles have larger reservoirs than those of micronutrients
Macronutrients are all substances that provide energy to the metabolism for optimal functioning, nitrogen and phosphorus are required in large amounts for organisms to survive.
What are macronutrients?It refers to those elements that provide energy to the body, these are proteins, carbohydrates and lipids.
Nitrogen and phosphorus, meanwhile, allow the development of metabolic processes, prevent infections and contribute to growth.
Therefore, we can conclude that the body requires a greater amount of macronutrients than micronutrients, nitrogen and phosphorus are required in large amounts for organisms to survive.

Red-green colorblindness is caused by a mutation in a gene on the X-chromosome. Bob (dad) has red-green colorblindness. Karen (mom) has color vision. Bob and Karen have a biological child named Taylor, who does not have red-green colorblindness. Taylor marries someone who has red-green colorblindness and they have 2 boys and 8 girls. Both boys have red-green colorblindness while all their sisters have color vision. Taylor is most likely:
Answer:
A carrier of red-green colorblindness?
Explanation:
This means she has one mutated X chromosome and one regular X chromosome. They cancel each other out because one is regular and one is mutated. But that one mutated X chromosome paired with the fathers mutated Y chromosome making both of the sons have red-green colorblindness.
ASAP HELP 100 POINTS Which describes nuclear fission?
starts when two atoms slam together, causing the larger atom to split into two smaller atoms
starts when a neutron slams into an atom, causing two atoms to form one, heavier atom
starts when two atoms slam together to form one, heavier atom
starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms
Answer:
to study the nature and size of the image formed by a convex lens using a candle and a screen activity file
The statement that describes nuclear fission is as follows:
Starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.Thus, the correct option for this question is D.
What is Nuclear fission?Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.
Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.
Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.
