Anika [276]

Answer:

B because the diffusion gradient is steeper there

Explanation:

Oxygen moves in the cell through the process of diffusion which means it moves from its higher concentration towards its lower concentration. More the difference in concentration, concentration gradient will be more steeper and diffusion will take faster.

So in this case cell, B cell consumes oxygen at a faster rate because it is more metabolically active therefore as oxygen is consumed at a faster rate the concentration difference in B cell becomes high and the diffusion gradient becomes steeper so oxygen will diffuse more quickly in cell B.

The correct answer is - A. codominance.

Codominance is an inheritance pattern that develops if there are two alleles of a particular gene in an organism and both are expressed together. It is not common as normally dominant allele masks the effect of recessive allele but here both traits occur.

Codominance is different from incomplete dominance as incomplete dominance expresses the dominant allele more than the recessive allele and expresses a mix of both.
