Answer:
Pavlov was studying salivation in dogs as part of a research program on digestion.
Explanation:
Ivan Pavlov discovered the concept of conditioning of reflex actions in dog when he was conducting a study on salvation in dogs.
He noticed that the dog (he was experimenting) start salivating as it hears the footstep of assistant that brings food. This made Pavlov to discover conditional stimulus.
Here the conditional stimulus was the sound of foot steps of assistant (as this was associated with the food) and the conditional response was salvation.
In normal cases, food is an unconditioned stimulus that produces unconditional response i.e salvation in dogs.
Hence, the correct statement is
"Pavlov was studying salivation in dogs as part of a research program on digestion."

that is the answer, I'm pretty sure
Yes, the the moth species Stigmella heteromelis is alive due to the presence of desired or favourable environment for their survival.
<h3>Factors affecting the presence of a specie</h3>
The moth species Stigmella will be considered alive if the environment that species of Stigmella needs for their survival is present because if the environment exist on the earth then it is possible that the moth specie Stigmella is present on this planet but if the there is no suitable environment.
Then we make the opinion that the specie of Stigmella heteromelis is not present on this planet so we can conclude that the presence of species on the basis of desired or favourable environment for their survival.
