Answer:

c. Crossing over

Explanation:

In meiosis, crossing over refers to the process where homologous chromosomes 'combine' with each other in order to exchange genetic material, which results in genetic variation. This process takes place during Prophase I of the first meiotic division.

Crossing over is extremely important for the variation - and survival - of a species, as it results in numerous genetic combinations that are passed from generation to generation.

Explain the reason it is important to make careful observations about the specimens when using a dichotomous key

enyata [817]

Dichotomous key is a tool - a series of questions and choices that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. The first step is observing the whole specimen you want to identify. Observing the habitat in which it is growing,its size and overall shape and some distinguishing features. It is very important to make carefully these observations in order to use the key.
