The five earth's spheres are biosphere, hydrosphere, atmosphere, geosphere and lithosphere.

An organism like polar bear might react with each of the sphere in the following way: The bear has its habitat on the land (lithosphere), he eat grasses and other small animals found in the biosphere. It drinks water, which is part of the hydrosphere. It breaths in oxygen and breath out carbon dioxide into the atmosphere. Its wastes is a source of food to decomposers, ( in the geosphere) which breaks it down for plants' use

Answer:

<em>The correct option is A. X, because organism X has the same role as the grasshopper</em>

Explanation:

In a food chain or a food web, a primary producer can be described as an organism which feeds on producers. The producers, in this case, are the corn stalks. Grasshoppers are primary consumers in this food web because they feed on the corn stalks. X is also a primary producer, just like grasshopper, because it feeds on the corn stalks which are the producers. Hence, option A is correct.

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)
