A "stimulus" is basically an event that happens in the outside environment that triggers a response. So, when you touched the dog's ear, that's a stimulus. The twitch is a response! So, A is correct. But just to be sure, let's look at the rest.
Artificial selection (B) is basically breeding: when humans breed organisms in order to obtain desired traits, like breeding dog species--this is not what our example is talking about.
Natural selection (C) is a similar process. When an organism mutates, but it actually helps it survive, it is more likely than the others to survive long enough to have babies. These babies are likely to have the helpful mutation, and so are their babies, and theirs, until a good portion of them have the mutation. This is NOT the example above!
And D, reproduction--well, let's just say it would involve a female dog and lots of babies, but that's not related to our example, so that isn't right either. The answer is A: a response to a stimulus.
Answer: A
<span>Preconventional stage - people think of their own needs and desires and obey rules in fear of punishment or in hope of reward.
Conventional stage - people respond based on their duty to others and decide what is acceptable or unacceptable based on other’s influence on them.

Answer:
Several studies show a relationship between academic achievement and self-esteem.
Explanation:
Pseudopsychology claims are psychological claims which are false, unfounded and not based on scientific/research results. These claims may sound persuasive and even true but they are indeed false. For example, people sometimes claim that white men are smarter and more intelligent than black men, this is a pseudo claim with no scientific backing.
Back to the question, the only option with a scientific/research claim is "Several studies show a relationship between academic achievement and self-esteem". The rest are just claims without scientific proofs, however persuasive they sound, they are at best pseudo claims.
Answer:
Most of the population of South America lives in the middle latitudes because the southernmost part of the continent, which belongs to Argentina and Chile, is one of the coldest places on Earth. This place, called Patagonia, is a mountainous region, with lots of rivers and lakes, and some valleys in which small cities are located (for example Bariloche, Neuquen, Comodoro Rivadavia, Rio Gallegos and Ushuaia in Argentina, and Punta Arenas in Chile). There are only a few more than 2,400,000 people living in this region, while the total population of South America rises to 440,000,000 inhabitants.
Hope this helps!!
