The East Pacific Rise is a mid-oceanic ridge, a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate
Answer;
During Prophase 1 of meiosis there is crossing over
, while,
Prophase of mitosis has no crossing over
Explanation;
-The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.
-The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
-During prophase 1 of meiosis; chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears.Crossing-over is the process that can give rise to genetic recombination. At this point, each homologous chromosome pair is visible as a bivalent (tetrad), a tight grouping of two chromosomes, each consisting of two sister chromatids. The sites of crossing-over are seen as crisscrossed nonsister chromatids and are called chiasmata.
I’m pretty sure ribosome? please don’t report if i’m wrong, havent done this in a while but hope it helps :)
Monosomy (the lack of one member of a chromosome pair) and trisomy (a triplet instead of the normal chromosome pair) are typically the result of nondisjunction during meiosis.
Answer:
The answer is B.
Explanation:
Living things grow and develop. Living things can reproduce. Living things respond to an environment they are in. Living things metabolize food for energy. In response all the answer choices except B are wrong because they can be done.
