The abnormal development or growth of the cells that make up the inner lining of the cervix is known as cervical ___________. hy

Hunter-Best [27]

The correct answer would be the second option. The abnormal development or growth of the cells that make up the inner lining of the cervix is known as cervical dysplasia. It is a pre-cancerous condition that involves an abnormal growth of cells in the lining of the endocervical canal which is the opening between the vagina and the uterus. A very common cause of developing this is the virus HPV or the human papillomavirus. It can be transmitted sexually and has many strains. This condition can still be cured when it is detected early. Without treating it, cervical dysplasia would develop to cancer.

How is cytokinesis different in animals and plants? Animal cells get pinched into two daughter cells by the cell membrane; the p

jasenka [17]

<h2>Let's review what cytokinesis is first.</h2>

Cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

A cleavage furrow is an indentation that appears in the cells surface when the cell is preparing to divide.

So, let's review our options:

A: Animal cells get pinched into two daughter cells by the cell membrane; the plant cell has to form a cell plate before it can create daughter cells.

This would be the correct answer. The only main difference between animal cell cytokensis vs plant cell cytokensis is the cell wall that animal cells lack. Animal cells get pinched into two daughter cells, by the cleavage furrow in the cell membrane, while the plant cell has to form a cell plate before it can create daughter cells.

B: Animal cells give daughter cells a full set of chromosomes at the time of division; plant cells give daughter cells a half set of chromosomes. .

This can be disproven. In meosis, a cell divides into four cells that have half the number of chromosomes. In mitosis, all chromosomes are kept. Both Plant & Animal cells both reproduce using both both meosis and mitosis, so this option is irrelevant.

C: Animal cells require an extra grow phase before cytokensis; plant cells move straight to cytokensis.

Both animal cells and plant cells have the same amount of "grow phases" before cytokensis. This option is irrelevant.

D: Animal cells begin cytokensis during anaphase, plant cells begin around the same time as telophase.

They both begin during the same time. This option is also irrelevant.

Select all the correct answers. Which two statements are true for the leading strand in DNA?

Ghella [55]

Question: Which two statements are true for the leading strand in DNA?

It is synthesized toward the replication fork.

It is synthesized in the 3′ to 5′ direction.

It is synthesized away from the replication fork.

It is synthesized in the 5′ to 3′ direction.

Answer:

The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"

Explanation:

Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.

Below are the choices that can be found elsewhere:

A) dimensional B) categorical
C) diathesis D) sociological

The answer is B categorical.

One criticism of the DSM noted by your author is that it adheres to a categorical model, which means that a person is seen as either having a mental disorder, or not having a mental disorder. There is little or no allowance for “degrees” of a disorder.
