Answer:
13
Explanation:
At the end of mitosis there would be half the amount of cells. Therefore, 13 daughter cells.
The structural components of the mammalian nephron where the transcytosis of water increases due to the action of anti-diuretic hormone is/are the collecting duct. ADH is a hormone made by the hypothalamus in the brain and stored in the posterior pituitary gland. It acts on renal collecting ducts via V2 receptors to increase water permeability, which leads to decreased urine formation. This increases blood volume, cardiac output and arterial pressure.
If a fragment of a
chromosome breaks off and then reattaches to the original chromosome at the
same place but in the reverse direction, what happens would result to
inversion.
I hope I was able to answer your question. Have a good day.
Hi,
I browsed through internet about the enzymes and found that there is an exercise with a list of three enzymes and probably you want to know, which are the enzymes that came from the stomach of Mondoni-a little mammal organism.
Please see the graphs i found, they contain the pH and temperature of the enzymes. So, we need to find the enzymes of Mondoni on the basis of these pH and temperature values.
The enzymes that came from Mondoni's stomach are A and B. These enzymes performed well at low pH and this indicates that they are probably digestive enzymes and have acidic nature.
Moreover, enzyme A and B perform better in low temperature and performed worst in extreme temperature like 80 degree Celsius. Their temperature range also matches with the temperature of mammals, therefore enzyme A and B came from Mandoni.
Hope it helps! :)
Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
