Explanation:

In the majority of cases, the extra copy of chromosome 21 comes from the mother in the egg.

In a small percentage (less than 5%) of cases, the extra copy of chromosome 21 comes from the father through the sperm.

In the remaining cases, the error occurs after fertilization, as the embryo grows.

Serum cystatin C in mouse models: a reliable and precise marker for renal function and superior to serum creatinine
Novosadov [1.4K]

In cases of acute renal failure, serum creatinine (SCR) and blood urea nitrogen (BUN) incorrectly predict the glomerular filtration rate (GFR). The possibility exists for serum cystatin C (CYS) to be a more accurate GFR marker. In order to examine the sensitivity of SCR, BUN, and CYS in identifying acute renal failure in mice, this study was conducted.

The conclusion of the study was that In mouse models, CYS can be utilized as an accurate and dependable marker for renal function. In comparison to SCR and BUN, CYS is more sensitive and detects kidney impairment early.

<h3>What is  glomerular filtration rate (GFR)?</h3>

A blood test called a glomerular filtration rate (GFR) measures how well your kidneys are functioning. Glomeruli are little filters found in your kidneys. These filters aid in clearing the blood of waste and extra fluid. How much blood flows through these filters each minute is determined by a GFR test.

Breeding livestock is graded "superior," "average," and "inferior" on the same traits as slaughter animals. In a 50-word paragra
BaLLatris [955]

Livestock producers and  breeders rank livestock on their ability  to produce high quality, efficient breeding  animals and market-worthy <u>offspring</u>.

To be able to effectively evaluate breeding  and market animals is of vital economic importance for the animal markets. The same traits  used to evaluate <u>high-grade slaughter  animals</u> are also important in the <u>grading </u>of  <u>breeding stock</u>.

When we judge livestock we  classify them as:

  • Superior livestock
  • Average livestock
  • Inferior livestock

We are looking for  the most desirable traits to fit our  particular market and genetic needs. The "Livestock Judging Manual" indicates that some of the most prevalent traits necessary to score a better rating are:

  • <em>Live weight</em>
  • <em>Fat depth</em>
  • Muscling

and many more. The most important of which is muscling given that an animal with more muscle will produce more desirable meat for the average consumer, and therefore can be sold at higher prices.

Does epinephrine trigger a direct or indirect signal transduction pathway? How do you know?
lys-0071 [83]

Epinephrine triggers a direct signal transduction pathway.

I know this because when epinephrine binds to it's receptor example on a muscle cell,this is known as a type of G protein -coupled receptor,signal transduction cascade is triggered and this involves the production of a second messenger molecule cyclic AMP(cAMP).

Epinephrine also know as Adrenaline or sus-phrine.

It is a vasoconstrictor,broncho dilator and a sympathetic stimulant.

It constricts the peripheral abdominal organs as well as a stimulating the heart beat thereby raising the blood pressure,it also relaxes the spasms of the bronchial muscles thereby promoting ventilation of the lungs.
