Put the steps of Cellular Respiration in order.

NNADVOKAT [17]

Answer:

The steps will be in order in the sequence 12,13,11,4 and 15

Explanation:

12. In glycolysis, glucose is converted into pyruvate. ATP and NADH ARE MADE.

13. Pyruvate is oxidized and converted into acetyl CoA in the mitochondria. Carbon dioxide and NADH are also made.

11. The acetyl CoA undergoes a series of changes and ATP, FADH2, NADH, and carbon dioxide are released.

4. NADH and FADH2 lose their electrons and get converted back into NAD+ and FAD.

15. Oxygen takes electrons and water is produced. 34 ATP molecules are released.

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%.
