For lunch, you eat french fries at a new restaurant. later that day you get the stomach flu and are vomiting all night. the next day, your friend offers you some french fries and you immediate feel nauseous. what component of classical conditioning does feeling nauseous represent?
a. conditioned response
b. conditioned stimulus
c. unconditioned response
d. unconditioned stimulus

A.conditioned response

Explanation:

A classical conditioning reflex occurs when an association is established between normal response or normal body function and a new stimulus. In the given example, the physiologically meaningful stimulus is eating French fries at a new restaurant and represents the unconditioned stimulus. French fries offered by friends was conditioned stimulus that replaced the unconditioned stimulus. Vomiting at new restaurant as it occurred in response to unconditioned stimulus was an unconditioned response. However, feeling nauseous in response to conditioned stimulus represents the conditioned response.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
