The pelagic region is divided into three zones. The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here.

dsp73

Answer:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

Explanation:

PP = large leaves

P'P' = small leaves

PP' = medium leaves

PP' was crossed with another PP' plant:

PP'   x   PP'

progeny = PP, 2PP', and P'P'

PP = 1/4  x 80 = 20 large size leaves plants

PP' = 1/2 x 80 = 40 medium sized leaves plants

P'P' = 1/4 x 80 = 20 small sized leaves.

<em>Hence the phenotypes would be:</em>

<em>20 large size leaves plants</em>

<em>40 medium sized leaves plants</em>

<em>20 small sized leaves.</em>

Why is the Calvin cycle considered a dark reaction?
Liono4ka [1.6K]

The correct answer for this question is (D) It can proceed in the dark.

Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>

The Calvin cycle proceeds in three stages:

1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate

2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH

3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.
