THE ANSWER IS LETTER D.no, because the virus is only contained in certain bodily fluids and survives for a limited time outside of the body

HIV is a kind of sexually transmitted disease which transmits with body fluids and infects host cell . The type of virus an HIV has is a cellular microscopic organism which is comprised of genetic material and a protein coat. To remain alive it needs a host cell.

In guinea pigs hair straightness or curliness is thought to be governed by a single pair of alleles showing incomplete dominance

Nimfa-mama [501]

Answer:

Frequency of allele S is p $= 0.4939$

Frequency of allele C is q $= 0.666$

The population is not in Hardy-Weinberg equilibrium

Explanation:

Given -

Number of individuals with straight hair $= 244$

Number of individuals with curly hair $= 444$

Number of individuals with Wavy hair $= 312$

Let "p" represents the frequency for allele for straight hair and "q" represents the frequency for allele for curly hair

$p^2$ represents the frequency of genotype "SS"

$p^{2} = \frac{244}{1000} \\= 0.244$

$q^2$ represents the frequency of genotype "CC"

$p^{2} = \frac{444}{1000} \\= 0.444$

$2pq$ represents the frequency of genotype "SC"

$2pq = \frac{312}{1000} \\= 0.312$

Frequency of allele S is p

$= \sqrt{0.244} \\= 0.4939$

Frequency of allele C is q

tex]= \sqrt{0.444} \\= 0.666[/tex]

For being in Hardy Weinberg's equation-

$p+q=1\\$

Substituting the values in above equation, we get -

$0.4939+0.666\neq 1$

hence, the population is not in Hardy-Weinberg equilibrium

Which of these statements best sums up evolution?

Ksenya-84 [330]

Evolution can be defined as the process of the change occurring in a population over a period of time through genetic variation. This genetic variation and the process of natural selection help a species to evolve by selecting the traits that helps it to better adapt to the environment. These genetic variations are inherited over time as the species continue to evolve.

Hence, the correct answer is 'change in population through genetic variation over time'.
