Answer:

(Choice B) 5 homologous pairs of chromosomes comprising a total of 20 chromatids.

Explanation:

Homologous chromosome are those two chromosomes which have same gene but different in shape and appearance.

Chromatids are the identical copies of chromosome. Single chromosome splits into double number of chromatids. In 5 pairs, 10 chromosomes are present so 10 chromosomes splits into 20 chromatids.

CC AC AC AC TC TC TC

Explanation:

Haplotype research served to discover the origin of genetic mutations that today manifest as pathologies.

It is very important to know that there are no equal haplotypes in two or more different humans.

They are the allelic constitution of multiple loci for the same chromosome.

Furthermore, haplotypes are very good for studying population genetics.

I leave you a table that will help you for this exercise or many more, where the haplotype system is outlined.

Alina [70]
<span>Body fat directly influences total body water. The influence of age, gender and fitness is also relative. Women and older persons tend to be lower on total boy water because they have lower fat free masses. Athletes tend to have higher total body water, therefore a younger athletic male would have the highest.</span>

Cystic fibrosis is an inherited respiratory disorder in which the mucociliary escalator no longer functions because of the prese
lakkis [162]

Answer:

C. lungs

Explanation:

Cystic fibrosis is a genetic disease caused by the mutation in the CF gene located on chromosome 7 which codes for the CFTR protein.

Cystic fibrosis transmembrane regulator protein or CFTR encoded protein regulates the movement of the water and chloride and sodium ions in and out of the cell.

The mutated gene forms abnormal protein which disrupts the movement of the ions and water in and out of the cell.

As a result of thick, the person develops thick and sticky mucus in the respiratory organs, especially in the lungs. Other organs of the body are also affected.

Thus, the lungs are the correct answer.

Answer:

Enzymes are proteins that assist as natural reactants to promote up the standard of chemical responses inside of cells.

Explanation:

Enzymes are proteins that assist as natural reactants to promote up the standard of chemical responses inside of cells. Substrate(s) bind to an enzyme at the enzyme's current (or catalytic) site. Products are published, and the enzyme is reusable.
