Answer:
Fertilizing an egg
Explanation:
it is a type of sexual reproduction
Answer:
The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange. If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.
An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population
Explanation:
That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.
Anyway, goodluck.

Explanation: Sudden Increase Factors:
- Since there are no predators, there are no ways they could be eaten, with this case, it significantly increases the population.
- Since there are a lot of females, and some males, the males could find mates, and have some baby reindeer, which also increase the population.
Sudden Decrease Factors:
- One decreasing factor is starvation. With there being so many reindeers, all the food is going away quickly. After a few years after the growth spurt, most of them probably died because of there not being a lot of food.
- Another decreasing factor is Old Age. Since there are 21 females, they are older than the babies, and they couldn't have lived much longer, and probably died.
- Another factor; sickness. With there being starvation, their immune system is degrading, and meaning sicknesses could come, so maybe a huge sickness // disease came, and wiped out quite a bit of the population.
