Compartmentalization of the cell means that there are structures inside the cell (within the cytosol) called organelles (nucleus, Golgi apparatus, endoplasmatic reticulum..) which are usually membrane-enclosed regions. Compartmentalization increases the efficiency of many subcellular processes by concentrating the molecules to a specific space within the cell. Each membrane-enclosed organelle has the characteristic position in the cytosol and specialized function in the cell.
<span>Introns are segments of DNA that do not code of any specific amino acid they stay in the nucleus.
Exons are segments of DNA that do code for amino acids(protein) & leave the nucleus to be translated.</span>
The reticular layer is composed of dense irregular connective tissue whose strength and toughness results from abundant collagen fibers.
The reticular dermis of the skin has many collagen fibers to support it because it provides strength and acts as a cushion. It also has elastin fiber that makes it elasticity.
Answer:
75%
Explanation:
The autosomal gene for baldness has two possible alleles: Hb (baldness) and Hn (nonbaldness).
A man and a woman, both heterozygous <em>HnHb,</em> have a son. Each parent produces gametes <em>Hn</em> or <em>Hb</em>.
The possible genotypes of their children, resulting from the combinations of those gametes, are:
In males, the Hb allele is dominant. Therefore, their son has a chance of 3/4 = 0.75 = 75% of having the Hb allele which determines baldness.
