option-A if there is a change in the oxidation states of atoms from reactants to products, the reaction in an oxidation reduction reaction describes the oxidation-reduction .

We know that oxidation is a process that increases the oxidation number, whereas reduction is a process that decreases the oxidation number. An oxidation-reduction (redox) is a type of chemical reaction wherein the electrons are exchanged among distinct strains Any chain reaction that occurs when the oxidation number of the a molecule, atom, or ion modifications by acquiring or losing an electron is an oxidation-reduction reaction. Reduction-oxidation reaction any chemical reaction in which one species oxidizes (loses electrons) while another species reduces (gains electrons) Oxidized. defines an element that has lost electrons and increased its oxidation number

A museum curator collects fossils from two different periods. He has 400 from one period and 204 from a later period. He plans t

matrenka [14]

Answer:

4

Explanation:

Number of fossils collected over period 1:

400

Number of fossils collected at a later period :

204

For each display case to have the same number of fossils ; the greatest number of fossils possible per case:

Obtain the greatest common factor of both 400 and 204

400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102

Hence, the greatest common factor (400 and 204) is 4

Hence, the greatest Number of Fossil possible per case = 4

Oduvanchick [21]

Answer:

Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.

Explanation:

To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
