Are humans more similar to trees or bacteria? How do you know?(1 point) A
Humans are more similar to bacteria because trees cannot move around their environment.
B
Humans are more similar to trees because bacteria are too small to see.
C
Humans are not similar to trees or bacteria. Humans are a special species that is not related to any other species on Earth.
D
Humans are more similar to trees because all plants and animals are part of the same domain.

Humans and trees are interdependent - we breathe in oxygen and breathe out carbon dioxide, while trees take in carbon dioxide and release oxygen.

Humans have about a thousand genes similar to those of bacteria, presumably because the genes are so vital that their DNA structure has remained much the same over millions of years of descent from a common ancestor.

Explanation:

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
