Think about a carbon atom that is released into the atmosphere from burning wood in a campfire. If it were to go through the who
Anna35 [415]

The correct order would be:

1. A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis;

2. A caterpillar gets the carbon by eating the tree's leaves.

3. A bird gets the carbon by eating the caterpillar.

4. The bird flies into a building and dies instantly. It falls to the ground.

5. The bird decomposes and the carbon returns to the atmosphere.

The carbon cycle is very similar to the water cycle, though it has its own unique ways. Once the carbon is released into the atmosphere, it will either be absorbed by the vegetation, or go up into the higher parts of the atmosphere. If it is absorbed by the vegetation, the organisms that eat the vegetation will get it in them. When the predators eat those organism they get the carbon into their organisms. When the predators die, they start to decompose. When they decompose, the carbon is released from them and it returns to the atmosphere, and the whole process goes all over again.

explain how the rate at which fossil fuels are transferred into the atmosphere, as shown in the diagram, has altered the carbon
oee [108]

Answer:

Explanation:

Over the past 250 year or two and a half centuries fossil fuels have been burnt at a very fast rate to meet the various human needs. These fossil fuels contains huge amount of carbon dioxide. And when these fossil fuels are burnt in power factories, power plants, cars etc. carbon moves from the fossil to the atmosphere. And since carbon dioxide is a greenhouse gas it traps more heat and hence there is a global temperature rise.

It is estimated that every year almost five and a half billion tons of carbon is released by burning fossil fuels. And since this amount of carbon dioxide is very huge for plants to convert all of them into oxygen via photosynthesis it leads to disbalancing in the carbon cycle that is more carbon dioxide is produced than the amount can be utilized which finally leads to rise in Earth's temperature as all of the extra carbondioxide ends up in Trapping more sun light.

Energy conservation in thioesters, acetyl-CoA and succinyl-CoA:
enot [183]

Answer:

B. ensure the production of GTP in the case of succinyl-CoA

Explanation:

Succinyl CoA like acetyl-CoA has a thioester bond with very negative free energy of hydrolysis. In this reaction, hydrolysis of the thioester bond leads to the formation of phosphoester bond with inorganic phosphate. This phosphate is transferred to histidine residue of the enzyme and this high energy unstable phosphate is finall transferred to GDP resulting in generation of GTP.

Hence the answer is B. ensure the production of GTP in the case of succinyl-CoA.

Stoping
Kay [80]

Answer:

As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
