Vitamin d - resistant rickets is an x-linked dominant bone disorder. a man with this form of rickets marries a normal woman. what proportion of the couple's daughters is expected to have vitamin d - resistant rickets? a. 50%b. 100%c. 25%d. 0%

b. 100%

Explanation:

Since, Vitamin D - resistant rickets is an X-linked dominant bone disorder, it is possible that the dominant bone disorder mask the expression of the other traits.

Given that,  A man with this form of rickets ; lets say X°X° marries a normal woman; (XX). The cross can be shown as:

         X°          X°

X       X°X       X°X

X       X°X       X°X

From the punnet square, it shows that all the offspring have an allele in each of their copy carrying a vitamin D - resistant rickets disorder.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.
