Incomplete dominant should be the answer

I believe the answer is incomplete dominance. Incomplete dominance creates a mix of the two phenotype(white and dark purple flowers) to create a third phenotype (lavender). Lavender is a mix.

Whereas, co-dominance would not be a mix but both traits would exist within the organism. In your question, it would be codominance if the dark purple flower and the white flower created a flower with white and dark flower pedals. This would not be a mix of the phenotype, but a co-existance of both phenotype.

I hope that helps! :D

Briefly outline the steps involved in glycogen synthesis and breakdown and explain the regulatory mechanism involved in glycogen
Elenna [48]

Answer:

Glycogen is synthesized and degraded by different pathways, which provide greater flexibility for energy production through its degradation or for storage in its synthesis and thus maintain control of both metabolic pathways.

Explanation:

Synthesis and degradation pathways:

1º.- activation of glucose units at UDP-glucose.

UDP-glucose is an activated form of glucose, which is formed in a reaction catalyzed by UDP-glucose, which is formed in a reaction catalyzed by UDP-glucose pyrophosphorylase. This reaction is an example of biosynthetic reactions that are directed by the hydrolysis of pyrophosphate (PPi-2Pi).

Many biosynthetic reactions are directed by the hydrolysis of pyrophosphate, which catalyzes pyrophosphate hydrolase or pyrophosphatase, and is very favorable thermodynamically.

2nd.- polymerization or addition of glucose units to glycogen. Two steps: addition and branching.

 UDP-glucose acts as the giver of glucose units for glycogen synthesis. Glucose transfer

from the UDP-glucose to a growing glycogen chain is catalyzed by glycogen synthase.

A branching enzyme [amyl (1,4 -> 1,6) -transglucosidase], moves a chain of about seven glucose residues, to form

bonds (α1-> 6) at the branching points.

To start glycogen synthesis, glycogen synthase is only effective when it is linked to glycogenin. Glycogenin is

an oligosaccharide carrier protein formed by glucose units with linkages (α1-> 4).

mars1129 [50]

Answer:

Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.

Explanation:

Options for the question are

A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.

B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.

C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.

D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.

Solution

Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.  

Hence, option B is correct
