jeff puts on a leather jacket over his sweater. the sweater becomes negatively charged. which statements about jeff’s situation are true?
a. the sweater has a tendency to attract electrons.
b. the sweater has a tendency to attract protons.
c. the leather jacket has a tendency to attract electrons.
d. the leather jacket has a tendency to attract protons.
e. the leather jacket has a lower tendency to attract electrons than the sweater.

Explanation:

It is known that when a neutral atom gains electrons then it tends to acquire a negative charge.

Whereas when a neutral atom loses electrons then it tends to acquire a positive charge.

Therefore, in the given situation sweater has become negatively charged, that is, it has gained electrons.

Thus, we can conclude that the statements about Jeff’s situation which are true are as follows.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
