A) True Mitochondria makes ATP from carbs and sugar.
Answer:
Firstly, they are all biogeochemical cycles. They cycle substances through the different systems. So this means that these substances like elements, compounds, and the like go through the hydrosphere, atmosphere, geosphere, and biosphere. It involves both the living and non-living things on Earth, all playing a role in transforming substances into something that can be used, only to be recycled again to provide for the other in a cyclic manner.
For example the oxygen cycle involves how oxygen is produced and used over and over. As we exhale Carbon Dioxide, it gets absorbed by plants which use it, along with water and light, to produce their own food in a process called photosynthesis. A by-product of this process is oxygen which we take in and use and we exhale Carbon dioxide again.
Answer:
Yes, it is a reasonable conclusion.
Explanation:
The long lasting gas that kept sunlight from penetrating the atmosphere was the key factor that promote a disturbance on the chain food. Without sunlight, plants could not produce their own energy, therefore they could not resist to this environment condition and die. That way, the herbivores could not feed and die as well. Also the carnivore could not survive because their supply of food of herbivores are not alive anymore. This scenario would promote a mass extinction of every dinosaur.
