Answer:

D. Meiosis is the only source of genetic variation for sexual reproduction

Explanation:

Sexual reproduction is the form of reproduction that involves two parent organisms which produce gametes or sex cells that unite while asexual reproduction involves only one parent to occur. One advantage of sexual over asexual reproduction is that there is room for genetic VARIATION among offsprings produced.

However, this genetic variation occurs in sexual reproduction as a result of a process called CROSSING OVER in MEIOSIS. Meiosis is the only division that produces gametes in living organisms and it only occurs in sexually reproducing organisms.

What structure bring water into the leaf from the roots?

liubo4ka [24]

STOMATA. These pores in leaves allow water to escape and evaporate--a process that helps to pull more water up through the tree from its roots.
