Answer from: snowprincess99447

Patau syndrome is the result of unique distribution of chromosomal pair of three in place of two.

Explanation:

A chromosomal disorder resulting in physical and intellectual disabilities of a child is widely known as Trisomy 13 or Patau syndrome. The symptoms include- defect in heart, abnor-mality in brain and spine, poor development of eyes, unusual number of fingers, a cleft lip or cleft palate and hypotonic or weakness in muscle.

The extra pair of chromosome, the pair of three, either in every cell or in few cells of the body is the main cause of this disease. However, it can also occur if the chromosomes are translocated.

Answer from: mia13290

Patau syndrome cause:

In some rare instances, a single cell in the body has triple copies of chromosome 13 when it's supposed to be only two copies. This results in Trisomy 13 and the Patau syndrome slowly follows. Patau syndrome can also occur when a small section of chromosome 13 gets attached to another chromosome.

Patau syndrome is similar to Edwards's syndrome or Down syndrome. This syndrome affects around 1 in 10,000 live births. Out of those affected, around 90 percent of the infants die in their first year of life. Those who survive are usually disabled severely either mentally or physically.

Answer from: Quest

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
