Answer:
CH3OH and NADH
Explanation:
The given chemical reaction is an redox reaction in which reduction and oxidation take place.
In the process of oxidation: electrons are loss while in the process of reduction: electrons are gained.
In the given redox reaction: CH3OH + NAD --> CH2O + NADH
NAD is reduced to NADH as NADH gains one hydrogen electron while CH3OH (methanol) is oxidized to CH2O (methanal) by losing electrons.
So, CH3OH (methanol) and NADH are the reduced forms while NAD and CH2O (methanal) are oxidized forms.
Elements that are unreactive can be useful for 'isolating' other volatile elements. For example, an element may be highly reactive with oxygen, so keeping it in air is not a safe option. In such cases, it may be useful to have a noble gas to store the element safely and ensure its stability. It may also have a purpose in experiments where it may act as a controlling agent or a container for the other reactions.

Answer and Explanation:
In Chemistry, the quantity or amount of a pure substance is given by:
- <em>mass</em><em> (in grams)</em>
- <em>Volume </em><em>(in millilitres or litres)</em>
- <em>Moles </em><em>(mol) </em>
Inter-conversion of units is allowed based on defined units and constituent of the substance.
I believe this explanation would be helpful and easy to follow.
Answer:
A tick living on a dog and drinking it's blood = Parasitism
Birds that live among cattle too eat insects stirred up by grazing = Mutualism
A clownfish living on the tentacles of an anemone provides nutrients too the anemone, and the clownfish is protected from predators = commensalism
A bear catching and eating a salmon from the river = predation
A bobcat catching and eating a rabbit = predation
A tapeworm living on the digestion system of a horse = parasitism
A Egyptian plover eating bugs off a giraffe or rhino = Mutualism
Bees gathering nectar and then spreading pollen too a flower = commensalism
