A prospective groom, who is healthy, has a sister with cystic fibrosis (CF), an autosomal recessive disease. Their parents are n

son4ous [18]

Answer:

Explanation:

From the given information:

Since the parent are normal; Let assume that their trait is Pp

The affected sister will be recessive in nature, so the trait will be pp

Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.

Also, the wife will be carrying a heterozygous trait since she is normal as well.

However, using Hardy-Weinberg assumption:

$q^2 = \dfrac{1}{2500}= 0.0004$

$q = \sqrt{0.0004}$

q = 0.02

Recall that:

$p+q =1 \\ p = 1 - q \\p = 1 - 0.02 \\p = 0.98\\$

Thus, $p^2 = (0.98)^2$

$p^2 = 0.9604$

$2pq = 2 \times 0.98 \times 0.022$

2pq = 0.0392

Finally, the required probability that there will be an affected offspring amongst the family is:

$= \dfrac{1}{4} \times \dfrac{2}{3} \times 0.0392$

$= \dfrac{1}{153}$

If a particular cell is known to be round and incapable of producing its own food, which one of these organelles would you assum

UNO [17]

If a particular cell is known to be round and incapable of producing its own food, such a cell would not be a plant cell. As such, from the options below:

CENTRAL VACUOLE
plasma membrane
cell wall
chloroplast

The correct answer as to which of the organelles the cell must have would be the plasma membrane.

central vacuole, cell wall, and chloroplast are all characteristic of plant cells.
All cell types have plasma membrane.

Hence, since it has been established that the cell is not a plant cell, the only organelle left that the cell cannot do without is the plasma membrane.

What are important functions of fiber in the body?

uysha [10]

Answer:

Fiber helps to prevent constipation in the human digestive system.

Explanation:

According to nutritionists fiber is very important in digestion as it increases the amount of stool , hence prompting for deification which generally reduces the amount of time waste stays in the small intestines .

Another reason is that it gets in touch with the schist that has been rejected or is of no value to the system and binds it to make it compact waste hence it is easier to move along the small intestine and the colon .

Finally it facilitates movement and exercise of the bowel , by prompting regular movement .
