Answer:
competitive exclusion.
Explanation:
When species from the same biological community explore very similar ecological niches, competition among them for less available resources in the environment is instituted. It is common, for example, that plant species whose roots use the same portion of the soil compete for water, minerals and other resources.
Knowing this, Russian biologist Georgyi Frantsevich Gause formulated the Gause principle, or competitive exclusion principle, the theory that ecological niches are unique to each species, and for two or more of them to coexist in the same habitat, it is necessary that their niches have different and sufficient characteristics.
Gause proposed this theory based on several observations that led him to conclude that if two or more species explore exactly the same ecological niche, the competition established between them is so sharp that coexistence becomes impossible. This can cause a loss in species diversity, and that is exactly what Robert Paine observed in his studies.

This question is missing the options. I've found the complete question online. It is a follows:
While watching television, Jason comes across an advertisement on a new soft drink brand. This advertisement reminds him that he is thirsty and wants to buy a beverage. In the context of reinforcement theory, the advertisement
serves as a(n) _____.
a. orienting reflex
b. stimulus
c. heuristic
d. cognitive map
Answer:
In the context of reinforcement theory, the advertisement serves as a(n) b. stimulus
.
Explanation:
In reinforcement theory, a stimulus is any external event that leads to a change in behavior, a response. Stimuli can actually be used to condition certain desired behaviors in animals and people by being paired up in ways that lead to specific responses. In the case described in the passage, Jason was led to feel the urge to buy a beverage because of the ad. Jason's behavior was a response to the ad, which means the ad itself is a stimulus.
Answer:
Neuron
Explanation:
Dopaminergic activity means "working on dopamine", related to dopamine. It increases the level of dopamine in brain in reaction to a stimulus. The adrenaline rush in the blood excites the pleasure received by the cells.
Various brain imaging studies show that an increased dopamine in the neuron when a heterosexual man looks at a picture of attractive women is due to the signals sent into the brain that increases the level of dopamine. It is a reaction of body to pleasure and a comfort received by the neuro-cells. It is also noted when they receive money as it also excites a stimulus reaction in the body. Thus, increasing the level of dopamine in the brain.
