It technically does affected because if your skin were to be rock hard than you would not be able to move at all so since our skin allows us to be more flexible than yes, I do think that it assists at moving.

Ket [755]

Answer:

The correct answer is option E. "DNA in both daughter cells would be radioactive".

Explanation:

Radioactive thymidine incorporation has irremediable effects in thymine and cytosine in bacteria such as E. coli. Although there are some reports of recovery of E. coli from UV-irradiation DNA damage, the presence of radioactive bases such as thymine is often irremediable. Therefore, after a dividing culture of E. coli exposed to radioactive thymine divides, DNA in both daughter cells would be radioactive.

A scientist samples a population of butterflies and finds that 56% are heterozygous at a particular locus. If the population is
d1i1m1o1n [39]

0.44  the frequency of the homozygous individuals in this population.

What is Hardy-Weinberg principle ?

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

From the Hardy Weinberg Law of Population and Genetics,

We have

x²+2xy+y²=1 and

x+y=1

where

x = frequency of the dominant allele in the population

y = frequency of the recessive allele in the population

x2 = percentage of homozygous dominant individuals

y2 = percentage of homozygous recessive individuals

2xy = percentage of heterozygous individuals

Given 2xy = 0.56

from here, y=0.28/x, (the frequency of the recessive allele ) can be obtained

we need to find 'x'

recall, x+y=1, x=1-y

substituting this gives us

y=0.28/(1-y), which becomes,

y(1-y)=0.28

y²- y + 0.28 (quadratic equation)

Solving this to find 'y' gives two imaginary values of y = 0.44 but ,

There is no imaginary solution  .

What happens to a virus involved in the lysogenic cycle?
-Dominant- [34]

Answer:

The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
