1 answer:
Savatey [412]4 years ago
7 0

Answer:

A. ATP

B. Yes, protons move with the concentration gradient

C. proton gradient across mitochondrial and chloroplast membrane.

Explanation:

A. During cellular respiration and photosynthesis, the free energy produced by the flow of electrons across the mitochondrial membrane and stroma lamellae leads to the formation of ATP molecule.

B. Due to the movement of electron down the reducing equivalent causes the flow of protons across the membrane. This leads to the formation of a concentration gradient.

C. The energy which drives the formation of ATP from ADP comes from the kinetic energy provided by the movement of protons across ATP synthase.

D. The back-flow of protons from intermembrane space of mitochondria to the matrix through ATP synthase and backflow from thylakoid lumen to stroma through ATP synthase add Pi to ADP and form ATP.

Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigatio
dedylja [7]

Answer:

C. The songs will become more similar to each other.

Explanation:

To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.

One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.

So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.

The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.

If none of the flower colors being bred don't show dominance, it would be pink only because if one showed dominance, than it means you would see that flower and that flower color only. Mixing red with white create pink, and therefore pink would be the only type of flower to have.
