Answer:
B) g = 0.5 h, v = 2 h^-1
Explanation:
Generation time is the time taken for a bacterial cell to divide and produce an offspring. Bacterial cells divide exponentially.
The total number of cells is given as =2n x initial number
[n = number of generations]
So if the total is 8 cells:
8=2n x 2
2n=4
n=2
That means 2 generations have arose
Generation time is given as 
where t=the time taken
if t=1hour and n=2
Generation time = 
= 0.5hour
Generation time, g =0.5h, and the rate of generation (growth rate), v is 2 per hour

Answer:
C. Darwin's explanation of natural selection
Explanation:
<em>According to Darwin, natural selection selects for traits that are more adaptable to an environment and individuals with such traits tend to reproduce and contribute more offspring to successive generations.</em>
As the environment keeps changing, organisms keep trying to adapt to the changes. Those who are able to adapt flourish more within the environment while the weak ones gradually get replaced in the population.
In the case of sickle cell heterozygosity and malaria; individuals that are heterozygous for the sickle cell trait are generally known to be less prone to malaria. Hence, this becomes a selection advantage over individuals with other genotype forms. Heterozygous individuals thus contribute more offspring into the population than other genotype forms according to natural selection law.
The correct answer is C.
3. is oxygen the others i would have to double check my book, so give me a minute and I'll try to put the rest in the comments
