Traveling in herds helps fight off predators, since there is strength in numbers. It's only when a deer is separated from the herd is when that animal is in trouble, and has a higher chance of getting eaten.

Males fighting for females is an example of survival of the fittest, so to speak. The female deer decides which male is the strongest which in turn helps pass on strong genes to the next generation.

Both of these traits help lead to successful reproduction and helps the species overall.

Pick the correct relationship between magnetic poles

A North poles attract both like and opposite poles


B South poles attract both like and opposite poles


C Opposite poles repel while like poles attract


D Like poles repel while opposite poles attract

Answers

Answer:

D
