Answer and explanation:
<u>The main difference between the economy in the southern United States from the economy in the northern United States in the nineteenth century was the fact that the southern states' economies relied upon agriculture and not manufacturing.</u> After 1800, southern plantations' chief crop was cotton, which was also the country's chief export. Forty years later, industrialization opened up a lucrative domestic market. Northern states were the ones to quickly shift from agricultural to industrial. Power-driven machines were used and, by 1860, the United States was behind only France and Great Britain in manufacturing.
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
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Austin wants to start budgeting so he first identifies his needs and his wants. This will help him create a solid budget because he is going to know what his priorities are. Knowing the things that he needs would make him allocate the proper money to get them. Then, after this is accomplished he would see if he has the money to spend on the things he wants such as entertainment and other fun things.
So Austin has to prepare a good budget so he stays out of trouble. He has to identify his income, see what kind of expenses he can afford, and determine his financial goals.
