Answer:

In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.

Explanation:

In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).

Hostility is related to coronary heart disease and may contribute to premature death.
erik [133]

Answer:

True

Explanation:

Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.

Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients  to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and  blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart.  It is said that some slight modifications to care for coronary heart disease  include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.

Hostility levels is also related as  a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.
