The red blood corpuscles have a pigment called hemoglobin that binds to the oxygen and carries it to the whole body in both the conditions, when the body is at rest or when the body is exercising. The oxygenated blood from the heart is carried to the various parts of the body and the de-oxygenated blood from various parts of the body is carried to the lungs where the exchange of gases takes place.

In humans, brown eyes are dominant to blue eyes. If a blue-eyed man has children with a brown-eyed woman whose mother has blue e
nlexa [21]

Answer:

50%

Explanation:

This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.

According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).

Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.

Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.

Answer:

Prokaryotic cell-- no organelles, no membrane.

Eukaryotic cell -- Have organelles and membrane.

Explanation:

For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.
