Answer:
The given blank can be filled with direct.
Explanation:
A battery refers to a chemical apparatus that is used to store electrical energy. A battery generates a direct current that is a current, which flows in only one direction. DC means direct current and it should exhibit fixed terminals, that is, negative and positive terminals, which cannot be altered.
As the batteries have fixed content, they possess fixed terminals, thus, they can store only direct current. Thus, the batteries produce direct current and produce a voltage in only one direction, and they exhibit a polarity of negative and positive.

Answer: Carbon Hydrogen and water
1:2:1
Explanation:
Carbohydrates are made of Carbon Hydrogen and water. Hence, they are represented by a general formula Cx(H2O)y.
Carbohydrates have carbon, hydrogen and oxygen in ratio 1:2:1, as is found in glucose (C6H12O6), Glycerose (C3H6O3), Ribose (C5H10O5).
Thus, in all sugars carbon, hydrogen and oxygen are found in ratio 1:2:1
The oxidation number of Mn is 0. Details about oxidation number can be found below.
<h3>What is oxidation number?</h3>
Oxidation number is the hypothetical charge of an atom within a molecule.
However, when an atom exists independently as an element, the oxidation number of such element is 0.
The oxidation number is assigned to an atom in a element/compound. It can either be +, -, or 0 and it tells us if electrons are lost or gained.
Therefore, according to this question, the oxidation number of Mn is 0.
