Rachel grows pea plants in her backyard. some of the pea plants have purple flowers, whereas others have white flowers. what does this indicate about rachel's pea plants?

The correct answer would be "the plants have genetic variation for flower color".

Explanation:

Genetic variation, as the name suggests, refers to the variety or differences present at gene or DNA level among different individuals or population.

More the genetic variation more are the traits or phenotype of the characters.

Different in DNA sequences and different combination of alleles or genes lead to increase in genetic variation.

For example,different shape, size, colors, appearance, texture, et cetera.

Similarly, the different flower colors also show the presence of genetic variation in a population.

Different combination of alleles lead to expression of different flower colors such as purple and white.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
