Therefore,the the cross to show the proportion is below

Bb,Bb,bb,bb,

Which is a product of the light reaction?
elena-s [515]

Answer: NADPH and ATP

Explanation:

The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.

When conducting a population sampling study, on the first capture attempt, we _______ the captured individuals.
deff fn [24]

When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.

<h3>What is the mark-recapture method?</h3>

This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.

Thus, option "D" is correct.
