Answer:
Yes, It is theoretically possible seeing that one or both of them have the gene for white eyes.
Explanation:
For the Hydrosphere, drag Pond and lake.
For the Atmosphere, drag gaseous nitrogen.
For biosphere, drag Mountain Range, micrograms, and coastal vegetation.
I don’t know about the Geosphere (sorry)
In classical conditioning, the response is elicited by a stimulus that comes before it.
Classical conditioning is an instance of automatic or unconscious learning. This learning process results in a conditioned response by creating associations between an unconditioned stimulus and a neutral stimulus.
In order to expose a naturally occurring reaction to a neutral stimulus initially, we can say that classical conditioning is doing that. Salivation in response to food functioned as both the neutral signal and the naturally occurring reflex in Pavlov's well-known dog experiment. By connecting the neutral stimulus (sound) with the unconditioned stimulus, the tone's sound alone could cause salivation (food).
The first step in the classical conditioning procedure calls for a naturally occurring stimulus that will prompt a response without any further instruction. An example of a naturally occurring stimulus is salivating in reaction to the smell of food.

Answer:
c) happened by chance
Explanation:
d and e answers are not correct:
mutations won't happen because of an environmental necessity, like being more efficient at eating grass, nor because a specific diet requirement, like eating seeds or grass. Mutations could happen if the organisms have the genetic pool to express a specific mutation dealing with a phenoypic character like longer teeth. If the organism doesn't have the genetic pool for developing longer teeth it will never have this feature, even if it keeps eating grass all its life.
A is not correct:
The mutation allowed the teeth to grow longer and to pass this feature to the next generation, but there is nothing that can predict an optimal length for eating grass to make them stop growing. Mutations are not a synonym of optimal features or benefit.
B is not correct:
It could happen that longer teeth arose in many members of the population, but we cannot say that it arose at the same time.
