<u>Answer:</u>

The series dilution method is the step wise dilution technique where the dilution factors remain constant in each step.  

The advantages of using the series of dilution method over simple dilution are stated below:

<em>a)        Aids in reduction of a dense culture of cells to a more usable concentration.</em>

<em>b)        In every step of dilution the specific amount of bacteria is removed. </em>

<em>c)        Helps in the estimation of concentration of an unknown sample.</em>

<em>This sums up the advantage of using the series dilution technique.</em>

I need help on this Asap. i also need an explanation to go with the answer.
Anna35 [415]

Answer:

For question 20. I believe the answer is C. There would be more iguanas with webbed feet.

Explanation:

It states the iguanas have adapted to different habitats on the island. The iguanas that have webbed feet will be better at getting food in water, but slower on land. So if the land starts to disappear and turns into more water, the iguanas with webbed feet will have a higher chance of survival. Meaning the iguanas with out webbed feet will die out as a population.

For Mendel to have postulated the law of independent assortment which of the following reasons had to be valid?
Jobisdone [24]

Answer:

Option (A).

Explanation:

Mendel is known as the father of genetics. He explains the concept of dominance and introduces the law of segregation and law of independent assortment.

The law of independent assortment explains that the segregation of one pair of character is independent on the other character. The law of independent assortment is valid because the trait used by the Mendel are located on different chromosome and does not show the linkage.
