Answer:

Photosynthesis is a critical component needed as a constant input into an ecosystem in order to keep it functioning.

Explanation:

Photosynthesis is the main process by which food enters in an ecosystem.

Photosynthesis is the process by which plants produce their own food from sunlight. This energy by photosynthesis travels from one organism to another in the ecosystem.

In the process of photosynthesis, oxygen is also produced which is required by organisms for respiration.

Besides this, both abiotic and botic components of an ecosystem are equally useful for the proper functioning of an ecosystem.

A man who has type B blood has children with a woman who has type A blood. A. If they are both heterozygous for this trait, pred

Ivenika [448]

Answer:

The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)

Explanation:

Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:

Blood type AB - iAiB

Blood type A - iAiA or iAi

Blood type B - iBiB or iBi

Blood type O - ii

According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:

iBi = iB and i

iAi = iA and I

Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:

- type AB (iAiB)

- type A (iAi)

- type B (iBi)

- type O (ii)
