Newton's law of gravity helped to change the initial view that the Universe was supported by some mystical force or object.
<h3>What did Newton say held the Solar system together?</h3>
Newton's explanation that the Solar system was held together by the force of gravity helped to explain so many observation which were not explained before.
Newton's explanation that objects were attracted to one another by the force of gravity helped to change the view that the Universe was held together by some mystical or magical force or that the earth and other planets were supported on something.
Therefore, Newton's law of gravity helped to change the initial view that the Universe was supported by some mystical force or object.

Answer:
d) The enzyme changes shape and can no longer speed up the reaction
Explanation:
Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
Answer:
Lower gravitational force due to lower mass.
Explanation:
Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.
In humans, the medulla region of the brain is mainly responsible for the regulation process of respiration. It is also called the respiratory rhythm centre. The chemosensitive area located near the respiratory centre sends signals across nerve impulses to alter the rate of expiration to eliminate compounds.
