After meiosis 2 there are 4 haploid gametes

Meiosis is responsible for making sex cells only

Final answer:

After meiosis, there are four haploid cells which can develop into gametes. This process is crucial for sexual reproduction in eukaryotic organisms.

Explanation:

After meiosis, the correct answer is that there are four haploid cells. During this process, one diploid cell (which has two sets of chromosomes) undergoes two rounds of cell division to create four haploid cells (each with one set of chromosomes). These cells can then develop into gametes, or sex cells, which can join together during fertilization to form a new diploid organism. This is a fundamental aspect of sexual reproduction in eukaryotic organisms.

In scientific notation, the number 39,940,000,000 becomes

Answers

Answer:

In scientific notation, the number 39,940,000,000 becomes $3.994 * 10^(10)$

Explanation:

Scientific notation is a way to represent a long numerical value in a short form.

The standard way to represent a number in scientific notation form includes -

Some power of 10 multiplied by the initial number between 0 to 10

The given number is 39,940,000,000

This can be written as

$= 3.994 * 10^(10)\n= 3.99 * 10^(10)$

3.994 x 10^10 since you move the decimal place 10 points

What will happen to a population of predators if there is a sudden increased in food for the prey

Answers

At first, the population of predators would spike and increase quickly, but then over time, gradually decrease.

(This is because at first there's more food, so the predators population increases. But overtime it begins to level out and the predators' population catches up with the prey, and in result, doesn't continue increasing.)

A sudden increase in food would result in prey eating and breeding which would mean more the predators could do the same. The predator population would increase with the population of its prey.
