To maintain a line of pure-breeding peas, selective breeders would use a technique called artificial cross-pollination. This is a technique were breeders transfer pollen from the anthers of one pea plant (male parent) to a stigma of a flower (female parent).
This technique was developed by Gregor Mendel, the founder of the science of genetics. He was a monk who dedicated his time in research about how genes of plants are carried over through specific species. In his controlled experiment he used the pea plant because they are cheap and readily available from merchants who sold them in different classifications. He also used pea plants because they have the capacity to self-pollinate or cross-pollinate.
Deletion because it worse then a substitution since your deleting something
Ok, so the Answer is D. Wind because wind can be transformed into mechanical energy in the wind tube and the wind tube makes electricity.
The key function of classical conditioning is to allow an organism to <span>learn new species-typical behaviors.
Classical conditioning refers to when two or more different stimuli are joined in order for an organism to learn something it didn't know before. The more you repeat the conditioning, the faster the organism will learn. For example, Pavlov experimented with dogs - each time they were presented with food, they would also hear a bell. So each time dogs heard the bell, they knew that they would be getting food soon.

If a bacterium cannot use citrate agar will not change its color (stays green). On the other hand, if bacteria have the ability to use citrate, the medium will change its color from green to blue.
This happens because citrate agar contains pH indicator such as bromothymol blue which transforms from green to blue in alkaline conditions.
