11. c. crossing-over. Notice how one of the bottom arms of each of the gray and white chromosome overlaps with each other, then their genes switch to the other's arm. That's called crossing over, when homologous chromosomes' genes flip-flop with each other.
14. b. meiosis. Gametes are special daughter cells that are either sperm or egg for sexual reproduction. Since genes are shuffled and daughter cells are not like parent cells, this is meiosis. 1 parent --> 4 non-identical gametes.
16. a. centromeres. During late prophase and all of metaphase of mitosis, identical sister chromatids are fused together at the center of the chromosome "X" by what's called a centromere. Then, during anaphase, the sisters are pulled apart, at these centromeres, by spindles attached to centrioles toward opposite sides of the cell.
17. c. Metaphase only. Although late prophase has this appearance of chromosomes, the best answer is probably only metaphase. It's not in anaphase because that's when sister chromatids are pulled apart at their centromeres.
Answer;
Evolutionary psychologists; behavioral psychologists
Evolutionary psychologists look at the genetic tendencies that we share as a species, whereas behavioral psychologists explore human genetic differences.
Explanation;
-Evolutionary psychology is a theoretical approach to psychology that attempts to explain useful mental and psychological traits such as memory, perception, or language,as the functional products of natural selection. Evolutionary psychology is focused on how evolution has shaped the mind and behavior.
-Behaviorism is concerned with how environmental factors affect observable behavior. The behaviorist approach proposes two main processes whereby people learn from their environment: namely classical conditioning and operand conditioning.
The species of an organism with more favorable traits will live longer to reproduce and evolve while with natural selection, the organisms will get picked out and eaten
