1. which statement describes a species that is at carrying capacity?
a the number of births equals the number of deaths.
b the number of births is greater than the number of deaths.
c the number of births in one species exceeds the number of deaths in
another.
d the number of births is less than the number of deaths.

A. The number of births equals the number of deaths.

Explanation: The carrying capacity of a specific species within a particular environment, is the maximum population of the species that can be sustained by the environment without harming the environment. The population will fluctuate about this line or point. A greater number of births than deaths will increase the population. A greater number of deaths than births will decrease the population.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
