What is different about normal cell division and cancer cell division?

Answers

Answer 1
They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells.
Answer 2
Cancer cells are cells gone wrong — in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy. Over time, these cells become increasingly resistant to the controls that maintain normal tissue — and as a result, they divide more rapidly than their progenitors and become less dependent on signals from other cells. Cancer cells even evade programmed cell death, despite the fact that their multiple abnormalities would normally make them prime targets for apoptosis. In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body.

In normal cells, hundreds of genes intricately control the process of cell division. Normal growth requires a balance between the activity of those genes that promote cell proliferation and those that suppress it. It also relies on the activities of genes that signal when damaged cells should undergo apoptosis.

A client is being prepared for intrauterine (artificial) insemination. Which finding is the most suggestive to determine if the client is ovulating

Answers

Given what we know about uterine changes during ovulation, we can confirm that the most suggestive option to determine if the client is ovulating is the change in the cervical mucus.

During ovulation, many changes occur in the uterine in preparation for the possible fertilization of the egg and its subsequent implantations into the uterine wall. Of these changes, the most useful is the change to the mucus of the endometrium.

The endometrium is the outermost layer of the uterine wall, therefore, it is where the glands that will secrete hormones are located. During ovulation, the changes to this layer are clear and can provide unmistakable evidence of ovulation. One such evidence is the secretion of hormones specific to this stage in the menstrual cycle.

This was answered based on the complete question found online which states:

A client is being prepared for artificial insemination. Which finding is the most suggestive to determine if the client is ovulating?

A) slight weight gain

B) change in the cervical mucus

C) abdominal cramps

D) fall in body temperature

Answers

The statement that shows further instruction is needed is This shunt is the only surgery my baby will need.

Hydrocephalus occurs as liquid accumulates in the ventricles of the brain. This condition is considered serious because the build-up of fluid causes pressure on the brain.

One way to treat hydrocephalus is with a ventriculoperitoneal shunt. This is a device that is placed on the skull to decrease the liquid accumulated and the pressure.

This treatment is quite efficient but it often requires to be replaced by a new shunt after some years. This implies the kid will need more than one surgery if hydrocephalus continues.

Refers to the transfer of genes from donor to recipient microorganisms, where the recipient strain shows a change in genetic makeup at the end.

Answers

The mechanism by which genes are transferred from a donor to a recipient microorganism is called TRANSDUCTION. After transduction, the genetic makeup of the recipient cell is different.

Transduction refers to the genetic recombination mechanism by which bacteria can transfer fragments of DNA by using bacteria-infecting viruses called bacteriophages.

During transduction, a bacterial cell interacts by a conjugal bridge through which fragments of DNA are transferred to a suitable (host) recipient cell.

This mechanism (transduction) changes the genome of the host cells by generating genetic recombinants when the bacteriophages initiate a new cycle of infection.
