Chloroplasts: work to convert light energy of the Sun into sugars that can be used by cells. (photosynthesis)

Vacuoles: Main function is just a space-filler but can also fill digestive functions and their interiors can be used as storage for nutrients.

Answer:

Plant cells have cell walls and chloroplasts; animal cells do not. The cell wall surrounds the cell membrane, supports the cell, and gives the cell its shape. Chloroplasts capture energy from sunlight and convert it to chemical energy that the cell can use.

A chloroplast has stopped producing atp and NADPH

ElenaW [278]

The question is incomplete, so the complete question is as follows:

A chloroplast has stopped producing ATP and NADPH. Which of the following is most likely causing this?

a.The chloroplast has used up its supply of chlorophyll molecules.

b.Electrons have stopped moving through the electron transport chain.

c.The sun has risen and the chloroplast now can make more chlorophyll.

Answer:

b.Electrons have stopped moving through the electron transport chain.

Explanation:

ATP and NADPH are produced in the light dependent reaction stage of the photosynthesis that occurs within chloroplast grana.

ATP and NADPH are produced due to the movement of electron and proton (H+) in the electron transport chain, so if the movement of electrons will stopped in the electron transport chain, the formation of ATP and NADPH will also get stop.

Hence, the correct answer is "b".

A population of white-tailed deer inhabits a certain patch of forest in michigan. Which group of alleles can be considered the g

emmainna [20.7K]

Answer:

the dominant alleles of white-tailed deer in this population only!

Explanation:A group of individuals of the same species that interbreed with each other is known as a population. The study of change in genetics is called population genetics which includes genes and alleles.

Complete set of genes and their alleles that are present in a population is called gene pool. Gene pool includes both dominant and recessive alleles of every gene present in a population that can be transmitted in the next generation.

Population with high genetic pool has high diversity which increases the fitness of a population. As gene pool include all the genes and its allele in a population, therefore, the correct answer is all alleles of the white-tailed deer in this population only.
