Answer:

A)7

Explanation:

Birth rate = 8 turtles / year

Immigration = 10 turtles / year

Emigration = 2 turtles

Population growth = 9 turtles.

Lets suppose that the death rate for the given population is X.

By placing all the values in formula:

population growth = (birth rate + immigration) – (death rate + emigration)

9 = (8 +  10) - (X + 2)

9= 18 -( X+ 2)

or X= 7.

Answer:

C) Mass

Explanation:

Mass is made up by the amount of protons, neutrons, and electrons in an object. Mass is essentially the capacity of an object, which many times is mistaken for weight.

Shape, color, and size are all common ways to determine the species of the bird, when only looking at the egg.

Hope this helps! :)
