Answer:

c. Glycolysis evolved in an oxygen-rich environment.

Explanation:

Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.

Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twin

lidiya [134]

Answer:

81/256

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

mary (type o blood) and sam (type b- blood) have a daughter persephone whose blood type is b . mary can receive blood from:

den301095 [7]

Mary can only receive blood from O+ & O- blood group but not from her husband (B-) or daughter (B+).

<h2>Description of Mary's blood group</h2>

Mary's blood group is O+ as her husband is B- and her daughter is B+.So, it can be said that the daughter's positive(+) antigen should come from her mother (Mary).

AS O blood groups lack A and B antigens, it can donate blood to all other groups and cannot receive from all groups as it has A and B antibodies in the serum.

<h3>Universal Donor</h3>

Blood donors with type O- (O negative) red blood cells are known as universal donors, because their red blood cells may be used by people of any blood type.
