The prevalence rate of a disease refers to the number of people in a population that are affected by a particular disease. The only two reasons why the number of this set of people will decrease is if a cure is found for the disease or if those affected are dying.
Cure or death will reduce the prevalence rate.<span />

Genes a, b, and c are known to be in that linear order in an organism. A testcross is done that yields 20 double crossover proge
larisa [96]

Answer:

Explanation:

The observed frequency of the double crossovers (DCOs) is 20/1000, or 0.02. If there is no interference then this will be the same as the expected, which is just the product of the single crossover frequencies, that is, SCO frequency (a-b) x SCO freq. (b-c) = 0.02.

(a) Any combination of map distances whose product (a-b) x (b-c) = 0.02 is possible. However, three are most likely:

a 20 mu b 10 mu c

a 10 mu b 20 mu c

a 14.14 mu b 14.14 mu c

(b) The distances would be exactly the same.

(c) The expected number of DCO progeny would be 17.

TRUE or FALSE. | There is a gravitational attraction force between you and this computer.
kolbaska11 [484]

Answer:

true

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
