Answer: <u>Option B; photosynthesis</u>
Explanation: Carbon is present in the atmosphere in gaseous form as carbon dioxide majorly. And, only plants can take up CO2 and use it to make glucose. This reaction takes place through photosynthesis, taking place in the leaves of the plants. Rest activities mentioned in option A, C and D, these all release CO2 into the atmosphere.
Humans can exhibit both aerobic and anaerobic cellular respiration.
One of the main source of sediment in flowing water is soil erosion.
Explanation:
Soil erosion is the washing away of top most layer of soil due to various reasons.
Agents of soil erosion are: wind, water, animals, ice or gravity.
Water is one of the biggest agent or cause of soil erosion. Water carry lots of energy in its motion. When water moves from any area it carries away topmost layer of soil with it. The soil that is being carried away by water is sediment.
When this water reach river, lake or any other water source, sediments carried by them enters that source of water. Sediment results in water pollution.
What we know about shark and ray fossils comes from bones in rocks from the Cretaceous period in Mexico that left behind, their only hard parts.
<h3>Shark fossils</h3>
The idea of a stingray-like shark may seem like something out of a B-movie. But paleontologists have just reported the discovery of such a creature in Cretaceous rocks in Mexico. This strange shark combines a streamlined body with large, wing-shaped fins, an ancient animal unlike any seen in the fossil record.
<h3>Whose are the fossils?</h3>
Fossils are the remains or traces of living beings that inhabited the Earth in previous geological periods. Fossil remains are parts of animals or plants, such as a bone or some limb or organic remains that have been preserved in some way.
With this information, we can conclude that Fossils are remains or traces of animals and plants preserved in rocks.
