The widely accepted theory of planet formation, the so-called planetesimal hypotheses, the Chamberlain–Moulton planetesimal hypothesis and that of Viktor Safronov, states that planets form out of cosmic dust grains that collide and stick to form larger and larger bodies.

how do i describe the second part of anaphase one the cell cycle? as in after the division of chromosomes.
loris [4]

Answer:

<h2><u><em>I think this will help u with the answer that ur looking for. I hope so</em></u></h2>

Explanation:

<h3><u><em>Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Before anaphase begins, the replicated chromosomes, called sister chromatids, are aligned at along the equator of the cell on the equatorial plane. The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. </em></u></h3><h3><u><em> </em></u></h3><h3><u><em>During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. </em></u></h3><h3><u><em> </em></u></h3><h3><u><em>Anaphase ensures that each daughter cell receives an identical set of chromosomes, and it is followed by the fifth and final phase of mitosis, known as telophase. </em></u></h3><h3><u><em> </em></u></h3>

An adolescent client with an antisocial personality disorder has been admitted to the hospital because of drug abuse and repeate
Yuri [45]
The correct answer is "identifies the feelings underlying the acting-out behaviour ".
This statement shows that the adolescent is recognizing the feelings and is ready to talk about them. This willingness to express this indicates the development of insight and the sincere need to investigate the true source of these behaviours.
By stating that he will never behave like that again and that he will conform to society's norms, he is simply using expressions with no meaning to him. If he discusses seducing other adolescents, he is just manifesting the behaviour that led him to the hospital in the first place.
