In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by?

dedylja [7]

Answer:

A water molecule consists of two hydrogen atoms attached to one of oxygen and its general structure is angular. This is because the oxygen atom, in addition to forming bonds with hydrogen atoms, has two pairs of non-shared electrons.

An autosomal recessive disease has an incidence of 1/10,000. What is the approximate frequency of heterozygote carriers for this

goblinko [34]

Answer:

Option B

Explanation:

Given

Number of incidences or frequency of an autosomal recessive disease $= \frac{1}{10000}$

As per Hardy Weinberg's equation, frequency of a recessive genotype is $q^{2}$

$q = \sqrt{\frac{1}{10000} }\\ q = \frac{1}{100}$

As per first equation of Hardy Weinberg's -

$p+q=1$

so ,

$p = 1-q\\p = 1-\frac{1}{100}\\p = \frac{99}{100}$

$p^2 = (\frac{99}{100})^2\\p^2 =\frac{9801}{1000}$

As per second equation of Hardy Weinberg's -

$p^{2} + q^{2} + 2pq=1$

Substituting the given values in above equation, we get -

$\frac{9801}{10000} + \frac{1}{100} + 2pq=1\\2pq = 1-(\frac{9801}{10000} + \frac{1}{100})\\2pq = 0.99%\\OR[tex]2pq=1$ %

$2pq = \frac{1}{100}$

Hence, option B is correct.
