For every one NADH molecule oxidized at complex I, 10 HYDROGEN IONS are pumped across all of the complexes from the mitochondrial matrix to the inner membrane space
Cellular respiration has three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation.
<h3>
What is Oxidative phosphorylation ?</h3>
During oxidative phosphorylation, the reduced form of nicotinamide adenine dinucleotide (NADH) helps to carry electrons from one reaction to another across a series of molecular complexes.
- The electron transport chain of oxidative phosphorylation is coupled to the generation of an electrochemical proton (H+) gradient across the mitochondrial inner membrane.
- Subsequently, this proton H+ gradient is then used to produce ATP by an ATP synthetase.

Answer:
Secondary
Explanation:
There are several levels of prevention. You might confuse this with primary prevention. Primary prevention is preventing infection, so it has to be done before the patient caught the disease.
The needle-exchange program aims to reduce the spread of blood-borne disease(HIV, hepatitis, etc) from the multiple usages of the same needle. Since the disease already exists, this will be secondary prevention.
The answer is D ( Hypodermis )
Hope this helps !! :)
The best answer is A.
As soon as the blood vessel wall is broken or damaged, a series of reactions activate platelets so that they stick to the site of injury. The platelets are able to hold to the blood vessel wall by means of a protein substance called von Willebrand's factor.
Collagen and thrombin then act at the site of injury and induce platelets to clump or stick together, forming a mesh that plugs the broken part. Special clotting protein help sequester more platelets to the plug which finally becomes a blood clot.
Considering that the population of white flowers in which the frequency of red allele CR is p= 0.7, then the frequency of the white allele (CW) in the population will be p=0.3. This is because the population contains white allele and the red allele therefore the two should add up to 1. Allele is the alternative form of a gene that codes for a specific trait.
