Answer:

isometric contraction

Explanation:

Isometric contraction is a class of contraction where the muscle maintains a constant length as tension is produced, thereby the length of the muscles does not change during this process. Isometric contractions are performed without joint motion. They are appropriate for the rehabilitation of musculotendinous traumas due the muscle maintains a static position and contraction intensity can be controlled. This type of contraction is common for the muscles in the hands and arms.

lapo4ka [179]

Answer:

Yes, I think this scheme can work. The chippings will provide enough ethanol to power the mower. The mover requires up to 15% ethanol. As he is distilling it to 95% ethanol, it would be more than enough for the mower to work. And also he can use the remaining ethanol for other purposes like powering Joe’s car or to create alcoholic beverages to drink when Joe’s friends come over to watch UCLA football games on Saturday afternoons.

(This is about DNA)
n200080 [17]

Answer:

B. 20%

Explanation:

The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).

Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.

This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.

Since they are equal in amount, there must be 20% of each.

Therefore the answer is B. 20%

There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.

Hope this helped!

Why did classical astronomers conclude the heavens were made up of sphere?
Natalija [7]
The classical astronomers concluded that heavens were made up of a sphere, because heavens were thought to be perfect and spheres (circles) are a perfect shape. It was Plato who argued that geometrical figures were spheres and everyone agreed to him. It was also believed that the perfect motion of spheres was a uniform circular rotation.
