Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred
I believe it’s true, correct me if i’m wrong
Answer:
I think the answer would be lichens, because lichens are formed during primary succession as a pioneer species. During secondary succession, grasses are usually the pioneer species.
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 .
The answer is Catecholamine. It is any of a class of aromatic amines that includes a number of neurotransmitters such as epinephrine and dopamine. The adrenergic receptors are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine (noradrenaline) and epinephrine (adrenaline). These three - catecholamine, peptide hormones and eicosanoids acts as extracellular membrane receptors which means that these receptors are embedded in the membranes of cells. They act in cell signaling by receiving (binding to) extracellular molecules.
