arlik [135]

Answer:

Purebred can be described as organisms that result from true-breeding. True breeding occurs parents who have a homozygous genotype are crossed so that the offspring produced might be similar to them. The alleles of the desired genes will be the same in the parents which will breed and produce similar alleles in their offsprings.

However, the phenomenon of pure breeding limits the gene pool and genetic variety becomes limited by such methods.

Afina-wow [57]

Answer:

B)Photosynthesis releases oxygen into the atmosphere while aerobic respiration removes oxygen from the atmosphere.

Explanation:

Only option B satisfies the answer to the question.

We know that photosynthesis is the process whereby green plants manufacture their foods in the presence of carbon dioxide and sunlight. Carbondioxie in the environment is used to manufacture food in plants. The bye product of photosynthesis is oxygen gas. Oxygen gas is used for aerobic respiration in animals and is essential for their life. This way photosynthesis adds to the pool of oxygen in the atmosphere and aerobic respiration removes from the pool.
