Answer: Mutations DUH it keeps saying Mutations over and over
Explanation:
Our bodies sweat to cool us off and to avoid overheating. Therefore, I think the answer would be "liquid (sweat) sitting on the skin's surface" because sweat has been produced and is sitting to cool the skin. The other options seem to be either after the sweating occurs or interrupts the process of cooling. The third option is my best, process-of-elimination guess. Hope this helps.
Catalyst is a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence a catalyst can be recovered chemically unchanged at the end of the reaction it has been used to speed up, or catalyze.
Answer: In direct effect, the person is directly affected by the source. For example, if a volcanic eruption occurs and lava flows outward, the area surrounding the volcano - including human establishments and organisms that reside there - would be affected (DIRECTLY); however, we observe that acid rain forms after this. This is because the sulfurous gases from the eruption mix with water vapor in the atmosphere. Another indirect effect of this is actually positive - radiation reflection. When a volcano eruptions, it releases gases like sulfur dioxide. Sulfur dioxide would react with other substances and produce aerosol particles. Aerosols can have huge impacts on our climate as they reflect light. This is evident when Mount Pinatubo erupted in 1991, and as a consequent, the aerosols that were produced from its gases cooled the area for 4 years.
Answer:
That would be A. Covalent bond!
Explanation:
Since the bond formed is an ester bond, these bonds are covalent in nature and so the answer is A.!
