11Alexandr11 [23.1K]

Answer:

Cystic fibrosis (CF) is more common in Caucasian individuals and is inherited with an autosomal recessive inheritance pattern.

Explanation:

Cystic fibrosis (CF) is a condition of genetic origin, which affects organs such as the lungs, pancreas, intestine and liver. CF is characterized by the production of very thick and viscous mucus, and promotes the formation of cysts and fibrosis of the affected organs.

CF is an inherited disease that is transmitted in an autosomal recessive pattern, that is, the altered gene is required to be on both chromosomes of the allelic pair, in order to be expressed.

It is a very common disease in Caucasian individuals, especially those of European descent.

Determine whether the statement is true or false. Suppose P(t) represents the population of bacteria at time t and suppose P'(t)
Lorico [155]

Answer:

TRUE

Explanation:

If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.

The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.

The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.

When t < 3, P'' > 0.  

When t = 3, P'' = 0.

When t > 3, P'' < 0, because the rate of population growth is slowing down.

Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..
