Which of the following is a correct statement about evolution?
alexandr402 [8]

Answer:

C. Evolution is a change of allele frequency from one generation to the next

Explanation:

Evolution is the gradual change that occurs to living organisms over successive generations. According to Charles Darwin, these changes aid in the adaptation of the species of an organism to their environment. In other words, it makes them better fit.

Charles Darwin further stated that since evolution is dependent on natural selection i.e selection of the best fit by environmental factors, the changes that the organism undergo are genetic. Hence, evolution is a change of allele frequency from one generation to the next.

Katyanochek1 [597]
<h2>Mesophyll cells</h2>

Explanation:

The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts

Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis

Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side

The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves

The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases
