NOTE some key features of theories that are important to understand from this description:

B.  Theories aren't likely to change. They have so much support and are able to explain satisfactorily so many observations, that they are not likely to change. Theories can, indeed, be facts. Theories can change, but it is a long and difficult process. In order for a theory to change, there must be many observations or evidence that the theory cannot explain.

Explanation:

From the passage or description of the word scientific theory, it was concluded that:

1. Theory is a scientific explanations, well defined or established that now new evidence will change them

2. Theory may change or their interpretation may change, but not the facts that are well determined in the theory.

3. Theory can be used to predict unobserved situation or phenomenon based on the facts well established by the theory.

4. Theory in scientific terms is different from general usage of the term.

As theory in science explaexplainsin well defined facts, while the general usage are often times mean hunch or speculation.

Dr. Jekyll is in distress and believes that he is at Dr Lanyon's mercy for help.

Explanation:

We see from his letter that Dr. Jekyll is very distress. He uses a phrase like "I am lost" and says his whole life and honor depend on Lanyon, words that very clearly paint the picture of the agony and worry.

We see that he thinks all his life depends on Lanyon's mercy and his help, even though there is a hint the request might be dishonorable for some.

The other options for answering are wrong because

we don't see if Jekyll and Lanyon are as close as beforewe still don't know if Lanyon will help Jekyll or not, therefore, Jekyll is not upset because of that

Explanation:

These are the answers that best express the ideas of the text. In this text, we learn about how the brain operates. We learn that memories are created in various different ways in the brain. However, it seems like memories are not particularly reliable, as the brain tends to add or modify information that tells a story better. Therefore, it is difficult for someone to be sure whether the details he remembers from his childhood are indeed accurate.
