Why don’t recessive traits always eventually disappear from populations?

1 answer:

5 0

Because the recessive trait might not show, but its there, lets say B is brown eyes and b is blue eyes, BB is brown, Bb is brown, and bb is blue, if B is present, brown will always show, but as long as the little b is there, there is a chance of the kids having blue eyes, sure most people would have brown eyes, but a lot of the people with brown eyes would be Bb

How does penicillin kill bacteria? Penicillin augments the body's natural ability to enzymatically degrade bacterial peptidoglyc

Liono4ka [1.6K]

Answer:

The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.

Explanation:

Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.

These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.

Assuming a typical monohybrid cross in which one allele is completely dominant to the other, what phenotypic ratio is expected i

IgorC [24]

Answer:

Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1

This shows the dominance of allele A.

However if two of the F1 generation are crossed then:

The F2 is AA,Aa,Aa,aa the phenotypic ratio is

3 ; 1

While the Genotypic ratio is ratio;

1AA : 2Aa Aa; 1aa(1 ;2;1)

just olya [345]

Answer: Option b

Explanation:In chemistry,

before any reaction would occurs, reactat must be able to overcome some certain amount of energy which is called the activation. The activation energy is usually the heat that is suppled.it is also refered to as the minimum energy needed before any reaction can take place. For reaction to take place, there must be an equilibrium( at constant temperature and pressure.

What happens to an animal cell in a hypertonic solution?

jarptica [38.1K]

The answer is that cell will shrink.

If you put an animal cell in a hypertonic solution means that concentration of the solutes is greater outside the cell, in the solution, than in the cell. Consequently, the water concentration of the cell's cytoplasm is higher than that of the hypertonic solution. Since the aim is to balance water concentration on the inside and outside of the cell, the water will exit the cell. The cell will lose water and, consequently, will shrink in size.
