Answer: D

Explanation: The atmosphere in Venus is primarily composed by carbon dioxide (CO₂), about 2% of nitrogen (N₂) and less than 1% of Oxygen (O₂), while in Mars, besides having almost the same amount of carbon dioxide and nitrogen, it also has argonium (Ar) in its composition. Having this in mind, it's easy to notice that Earth's atmosphere and the other two planets <u>differ in its chemical compositions</u>, as we can see in alternative D.

Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop

Answer: Option D

<u>Explanation:</u>

Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.

Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat  is removed and as the product is not that stable it is liable to stop the reaction.

How does biodiversity support healthy ecosystems
pav-90 [236]

ANSWER: Biological biodiversity refers to all the different kinds of life that are obtainable in a particular ecosystem, this include all the plants and animal populations that are found in a particular geographical area.

Biodiversity supports healthy ecosystem because it enhances the productivity and the survival of the ecosystem. For instance, in a situation where there are large number of different plant population in an ecosystem, such population will present variability in genetic make up. If a negative event occur in the ecosystem, it will be possible for some plants to survive. But, in a situation where it is only one type of plant that is obtainable in the ecosystem, it will be quite easy to wipe all of them out at once. For instance, a disease outbreak can easily destroy all the plants.

<span>I believe it is light, but this is kind of a confusing question. Technically there is a independent and dependent variable in the question. The variable being manipulated is light, and the earthwork activity depends on the light. </span>
