Answer:
a. intragenerational
Explanation:
Intragenerational mobility by definition: refers to a person's social movements throughout his or her lifespan. It wouldn't be structural or life cycle because those are remotely related to social mobility. Lastly it wouldn't be intergenerational because by definition is means: elating to, involving, or affecting several generations. Which is not related to social mobility at all.
The answer is <span>B) three chromosomes in any one set.
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes (so choice C. does not indicate a genetic problem). There are in total 46 chromosomes (23 pairs in 2 copies), that differs in lengths (so choice D. does not indicate a genetic problem). Speaking of a pair of sex chromosomes, there could be two X chromosomes in females or one X and one Y chromosome in males (so choice A. </span><span>does not indicate a genetic problem).
But, having three chromosomes in </span>any one set suggests a presence of trisomy, which is <span> a condition in which an extra copy
of some chromosome is present. This results in a genetic disorder.</span>
