Yes! You're right. It is evaporation. Since evaporation is a cooling process, it takes the heat of a surface away. - releasing heat
Answer:
A) The catalyst makes lower energy pathways available.
Explanation:
A catalyst is a substance which speeds up a chemical reaction without itself being used in the reaction. Activation energy is the thresh hold energy which is required to initiate a chemical reaction. In the absence of catalyst, the activation energy is high therefore reactions are slower. But, presence of catalyst lowers the activation energy required to initiate the reaction as a result of which the reaction gets an alternate energy pathway to proceed which is responsible for speeding up the reaction.
Answer:
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Answer:
Option B
Explanation:
In the book The Descent of Man published in 1871, Charles Darwin mentioned that the two recent most ancestor of present day human being live in Africa. These two recent ancestors of human beings are—chimpanzees and gorillas
