Answer: Amino acids are organic compounds (molecules) that contain amine (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid.
Explanation: The variation seen in naturally occurring amino acids arises from differences in this side chain.
1.Fossils
2.Location
Scientist use fossils to study body structures and compare them.
Scientist use location to study location to see how organisms used their features to cross water or survive in different temperatures.
Answer:
12 molecules of ATP can be made from one molecule of acetyl CoA.
Explanation:
If one molecule of acetyl CoA enter TCA cycle then it result in the formation of 3 molecules of NADH,1 molecule of FADH2 and 1 molecule of GTP that is equivalent to 1 molecule of ATP.
Now the reducing equivalent such as NADH and FADH2 enters electron transport chain and get oxidized to regenerate NAD+ and FAD along with ATP. 1 molecule of NADH produces 3 molecules of ATP whereas 1 molecule of FADH2 produces 2 molecules of ATP.
So that net gain of ATP is given below
3 molecules of NADH = 9 molecules of ATP
1 molecule of FADH2 =2 molecules of ATP
1 molecule of GTP = 1 molecule of ATP
As a result total 12 molecules of ATP is by the oxidation of 1 Acetyl CoA by TCA cycle .
Answer:
Mineral crystals that form when magma cools slowly are larger than crystals that form when lava cools rapidly. Minerals form when rocks are heated enough that atoms of different elements can move around and join into different molecules.
Answer:
Explanation:
The central nervous system (CNS) does not have capacity to repair itself but, the PNS or the peripheral nervous system can repair and regenerate itself. The PNS can regenerate its damaged axon only when its cell body or cyton and its neurilemma are intact. The proximal end of the cyton has growth cones. The axon grows from the cones.
