A client with the diagnosis of obsessive-compulsive disorder who has a need to wash his hands 50 to 60 times a day tearfully tel
alexgriva [62]
I understand that—maybe we can work together to limit the number of times you wash them."
<span>R: The nurse shows an understanding of the client's needs by not totally restricting the handwashing and by working with the client to set limits on the behavior. At this time the client is still too anxious to be capable of coping with the reasons for handwashing. Continued handwashing does not reveal an understanding of the underlying problem, nor is it a sign of progress. Telling the client not to worry denies the client's feelings and may close off communication.</span>

A cell with 80 chromosomes undergoes mitosis. How many chromosomes are found in the daughter cells? How many daughter cells are
Natalka [10]

Answer:

1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.

Explanation:

Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:

Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes

Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.  

Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.

Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.

Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.

Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.

which structure in the female reproductive system is comparable to the external reproductive organs in males
Oksi-84 [34.3K]
They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.
