1.Organisms pass on their genes to the next generation.
2.Giraffe offspring have different spots than their parents.
3.Fish have more offspring than can survive with limited resources
4.Individuals with the highest level of fitness survive to reproduce.

Correct answers are:

b - 2.

c - 4.

d - 3.

a is 1, b is 2, c is 4, and d is 3.

Explanation:

organisms passing on genes to their offspring (the next generation) is what we call hereditory genes.

giraffe offsprings having different spots than their parents is variation. each giraffe has a variety of different spots.

fish having more offspring and having limited resources means competition for the limited resources.

lastly, individuals who are stronger/faster strive to survive so the can reproduce.
