A model of cell division is shown here. A student evaluates the model and makes the claim that the cell division increases genet
ic variation in the daughter cells. Which evidence from the model supports the student's claim? A) Chromosomes pair in step 2.
B) Chromatids separate in step 5.
C) Chromosomes are replicated in step 1.
D) Chromosomes exchange genetic material in step 3.
D) chromosomes exchange genetic material in step 3
Explanation: the student claims that the cell division increases genetic variation, and D) is the only one which mentions exchanging genetic material/increasing variation
Water moves from the roots to the leaves through tissue called the xylem, in a process called transpiration. As water evaporates out of the leaf, more water is 'pulled upwards' to replace what has been lost.
