D. the 23rd pair of chromosomes

Explanation:

The 23rd pair of chromosomes in humans is of sex chromosomes as these chromosomes carry the genes to regulate the gender of the individuals. A human female has two copies of the X chromosome as sex chromosomes while human males have one X and one Y chromosome as their sex chromosomes. The Y chromosome carries "SRY" gene that codes for testes determining factor and regulates the development of testes in the embryo.

allsm [11]
Many disorders can be heritable through the generation. Knowing the patterns of disorder heredity, either it is dominant or recessive, autosomal or sex-linked is a great advantage in making a diagnose. It should be taken into consideration that some diseases can be influenced by environmental factors. For example, a person knows its parents had high blood pressure. That person has a predisposition for high blood pressure too. But, since heredity and family medical history is known, that person can prevent the appearance of the disease by taking care of its condition, performing physical activities, avoiding smoking, fat diet, etc.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure cal
nevsk [136]

Answer:

The answer is 46 chromosomes.

Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.

The process of homeostasis is very important in the maintenance of important indicators of balance in the body such as body temperature, body pH, etc.

Hence, when blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. This is a homeostatic response.
