Arlecino [84]

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

If a man and a woman, each with sickle-cell trait, were planning to marry, what information could you provide them regarding the
kiruha [24]

Answer:

I'll inform them that the possibility of all their future children/offspring being phenotypically sickle-celled is very high.

Explanation:

Sickle cell is an inherited disease condition in which the red blood cells of the blood loses its shape and hence, dies or gets broken down. It has to do with the blood genotype of an individual. There are three major types of blood genotypes in humans namely: AA, AS, and SS. SS is the recessive genotype that codes for the sickle cell trait.

Hence, a human with the sickle cell trait has a genotype- SS. Therefore, according to this question, a man and a woman, each with sickle-cell trait (SS), were planning to marry, This will mean that both the man and the woman will always produce a gamete with S allele, which will combine to form an SS offspring. In other words, all of the offsprings of this man and woman will be sickle-celled.

Archy [21]
If you check the barometric pressure and find that [sic] it is reading only 920 millibars ... two effects possibly responsible for this lower than average reading are 1) elevation (~2500' MSL) or 2) a LOW pressure weather system such as a mid-latitude or tropical cyclone. Also <span>A storm is approaching or barometer is read over a mountain</span>
