Answer:

Direct relationship.

Explanation:

There is direct relationship between growth rates and time which means growth rate of organism increases with the passage of time. Direct relationship means if one increases the other automatically increases and if one decreases, the other also decreases. The growth of bacteria becomes double when more time passes and vice versa. After every 20 minutes, the population of bacteria becomes double.

Name two substances in the body that will move based on the principles of diffusion
Nina [5.8K]
Hello there!

The principle of diffusion consists in the movement of substances through a membrane from a zone with high concentration, to a zone with low concentration, until the concentration is equal on both sides of the membrane. 

An example of diffusion is the process that happens when we breathe. Two substances in the body that will move based on the principles of diffusion are Carbon Dioxide and Oxygen. Carbon Dioxide will move from the bloodstream to the alveoli, and Oxygen will move from the alveoli to the bloodstream.

It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.

So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.
