Looking at the graph attached to this question, the correct option is this: THE MUSCLE WILL INCREASE IN TENSION TO A LEVEL GREATER THAN THAT MEASURED AT THE BEGINNING OF PHASE C.
Adding more load to a muscle increases the amount of work that a muscle is doing and increased work done by the muscles also results in increased muscle tension.

What did darwin believe was the primary cause of evolution?

lesya692 [45]

→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.

The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.

And how would that ↑ explain Evolution?

Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.

→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.

Muscles in animals are often found in pairs, because

babunello [35]

I'm not sure how exactly you wanted this question to be answered. You're either talking about the symmetry where animals would have two legs or two arms for example and thus producing a pair of each muscle on both sides of the body, or you're refering to the development of agonistic and antaonistic muscles where each of them served a different purpose; either extending or contracting.
