Explain using the term semi-conservation replication why we still

Biology
1 answer:
Basile [38]3 years ago
3 0

Answer:

Semi-conservation replication describes the mechanism of DNA replication in all known cells. This process is known as semi-conservation because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.

DNA is passed down to the next generation in big chunks called: Chromosomes.

Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around a 1 in 8 change that you would get no DNA from a great, great, great, great grandparent.

What most people forget, through, is that our chromosomes get mixed and matched before they are passed on. It is because of this "recombination" that your great, great, great grandparent's DNA is almost cetainly still lurking in yours.

The sodium - potassium pump usually pumps
ololo11 [35]

<u>Answer</u>:

Potassium inside the cell and sodium out of the cell

<u>Explanation</u>:

The presence of the pump can be seen in plasma membrane of the animal cell. Which can be followed by the ATP, this pump pushes sodium and potassium in completely opposite direction that can be said as against the concentration gradient. In one cycle of this pump, two potassium are ingested inside the cell and three sodium are taken out from the cell. Due to  more number of negatively charged proteins inside the cell, potassium ion contains more positive charge so pushed inside the cell. The potassium  is pumped through the channels.

A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these
-Dominant- [34]

Answer:

the frequency of the resistant allele after one generation is 0.989

Explanation:

Given that :

A farmer plants Bt cotton that is genetically modified to produce its own insecticide.

Of the cotton bollworms feeding on these Bt plants, only 5% survive

i.e the survival rate s  = 5% =0.05

unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide

Frequency of R allele = 0.01

In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.

According to Hardy-Weinberg Equilibrium ;

p+q = 1

Let p = R and q = r

R + r = 1

0.01 + r = 1

r = 1 - 0.01

r = 0.99

Now; the  frequency of the resistance allele after one generation can be calculated as :

q' = \dfrac{q(1-sq)}{1-(sq^2)}

where ;

q' = R

q = r

q' = \dfrac{0.99(1-(0.05 \times 0.99))}{1-(0.05 \times 0.99^2)}

q' = \dfrac{0.99(0.9505)}{1-(0.049005)}

q' = \dfrac{0.940995}{0.950995}

q' = 0.989

Thus; the frequency of the resistant allele after one generation is 0.989

Explain how natural selection helps the survival of a species.
Artyom0805 [142]

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
