Answer:

A - 3:1

Explanation:

In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.

| P | p

——————-

P | PP | Pp |

——————-

p | Pp | pp |

As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

Which is not a result of increased flexibility
jek_recluse [69]

The answer is: decreased circulation


Increased flexibility tend to be achieved by implementing stretching exercise. When we stretch, we would improve our blood circulation because the movement help the blood to flow in different type of direction. In the long run, exercises to increase flexibility would have positive benefit for our cardiovascular system.

Explain how prokaryotes can reproduce sexually and asexually.  In this discussion be sure to explain how the genetic material fr
Alexxx [7]

Answer:

During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.

Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.

In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.

In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.
