3 0

Answer:

Ratio = 9 : 2

Explanation:

We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.

First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:

Resistance (Equivalent) = R₁ + R₂ = 6 ohms

When these are connected in parallel, equivalent resistance becomes:

1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4

1 / Resistance (Equivalent) = 3/4

Resistance (Equivalent) = 4/3

Ratio = R(Series)/ R(Parallel)

Ratio = 6 : 4/3

Ratio = 18 : 4

Ratio = 9:2

A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that
n200080 [17]

Answer: D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.

Explanation:

When an organism is able to reproduce asexually as opposed to sexually, it means that they do not require a mate to make offspring. Offspring of such organisms will therefore receive all their genes from one source.

Such organisms are able to reproduce very fast when they are presented with adequate conditions especially because they do not need another organism to do so. They will neither have to waste much energy nor have to go through the whole sexual process so they will be able to produce lots of offspring.
