2. What happened to the green active site of the protein in the mutated CFTR protein

Biology
1 answer:
Anestetic [448]3 years ago
8 0
The cystic fibrosis transmembrane conductance regulator (CFTR) protein helps to maintain the balance of salt and water on many surfaces in the body, such as the surface of the lung. When the protein is not working correctly, chloride -- a component of salt -- becomes trapped in cells. Without the proper movement of chloride, water cannot hydrate the cellular surface. This leads the mucus covering the cells to become thick and sticky, causing many of the symptoms associated with cystic fibrosis.

What is the primary energy system to fuel cycling at 70% of VO2 Max for 15 minuets?
ANEK [815]
The primary energy system to fuel cycling for 15 minutes is THE AEROBIC GLYCOLYSIS SYSTEM.
There are different energy systems for fueling different types of physical exercise, the type of system that is used depend on the duration of the physical exercise. The energy system that exist are anaerobic glycolysis, aerobic glycolysis, phosphagem system and fatty acid oxidation. The aerobic glycolysis energy system relies on the complete breakdown of glucose. The pyruvate which is the end product of glucose oxidation is further broken down to acetyl coA, which then enters into the citric acid cycle. The aerobic glycolysis energy system is used for physical exercises that last between three to twenty minutes.

Bear pigmentation is subject to epistasis of the B alleles by the d alleles. B (black) is dominant over b (brown). D is dominant
White raven [17]

Answer:

9/16 black, 3/16 brown, 4/16 white

Explanation:

             BD         Bd          bD         bd

BD     BBDD      BBDd     BbDD     BbDd

Bd      BBDd      BBdd     BbDd      Bbdd

bD      BbDD     BbDd      bbDD     bbDd

bd       BbDd    Bbdd       bbDd     bbdd

A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.

To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.

The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.
