Which of the following is a correct difference between active transport and facilitated diffusion?
sweet-ann [11.9K]

Answer:

Active transport requires energy from ATP while facilitated diffusion does not

Explanation:

Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.

The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task

Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.

Galina-37 [17]

Answer:

a) How many genotypes will occur in F2

--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)

Reason-

This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.

b) 25% of all F2 genotypes would be recessive across the 5 loci

Reason-

This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.

c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE

d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE
