Answer:
(A). Energy is lost when machines don't work right.
Explanation:
The false statement from the choices is that energy is lost when machines do not work right.
The law of conservation of energy states that "energy can neither be created nor destroyed , they can only be converted from one form to another. "
- Option B is clearly covered by the statement of the law. All the energy of the universe is already created.
- Energy cannot be destroyed tallies with the Option C.
- Energy is transformed from one form to another validates the fourth choice. We can covert from thermal to mechanical energy and vice versa.
The only odd choice is that energy is lost when a machine doesn't work right.
Answer: Option C.
Enzymes lowers activation energy required for a given reaction.
Explanation:
Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.
Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
Answer:
selective breeding
Explanation:
Artificial selection is also known as selective breeding
<span>Studying the gross anatomy of a cadaver can show an individual the total physiology of a human. By dissecting a cadaver or deceased human, you can study the nervous and cardiovascular system as well as the organs and other internal tissues. For example, muscle origin and insertions on bone, blood supply to the muscle and nervous stimulation of the muscle can be studied. Other areas that can be seen are the location of major organs in the thorax and the blood supply to each of them. The discovery of how the cadaver died can also bee seen during the dissection in many cases.</span>
