How does crossing over increase diversity?

1 answer:

7 0

Crossing over does helps in genetic diversity as it provides with new genes combinations. In crossing over, chromatids exchange genetic information during the meiosis. This mixing of genetic information provides the offspring with its own unique genetic makeup with some similarities with the parent’s genetic system. Crossing over is very beneficial in terms of giving the offspring more variability that helps in becoming more resistant to a disease and be a better version than parents.

Which step can occur even more rapidly by PCR?a. target DNA removed from cells and isolated b. cloning host treated with calcium

lisabon 2012 [21]

Answer:

E. Gene is amplified by multiplication of cloning host

Explanation:

PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.

As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.

As humans grow, their bodies change.” Which statement best explains how humans grow?

Nata [24]

Answer: Cells undergo cell division

Explanation:

"As humans grow, their bodies change.” The statement that best explains how humans grow is that cells undergo cell division.

When cells divide, thus brings about the making of new cells. This is referred to as cell division or cell reproduction. In this case, a single cell divides and then brings about two cells, then these two cells later make four cells .... This is unique and vital for every living organisms.

During volume changes in the thoracic cavity, what is primarily responsible for changes in length?.

rusak2 [61]

During volume changes in the thoracic cavity, <u>Diaphragm</u> is primarily responsible for changes in length.

The main components of the respiratory system are the two lungs. They are located in the thoracic cavity, which is the area to the left and right of the heart. The rib cage safeguards the cavity. Other components of the respiratory system are supported by a muscular sheet known as the diaphragm.

The diaphragm contracts and pulls downward upon inspiration, or when the lungs inhale. The muscles between the ribcage tighten and pull upward at the same time. As a result, the pressure inside the thoracic cavity lowers and its size grows. Air rushes in as a result, filling the lungs.

Thus, diaphragm is responsible for the increase in length of the thoracic cavity.
