<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

For the given options:

<u>Option A:</u> Plus sign is written in a chemical equation to show the number of chemical species reacting or getting produced.

Option B: Subscript numbers are defined as the number of atoms of each element present in a compound.

For Example: In H_2O, 2 atoms of hydrogen element is there and 1 atom of oxygen element is there.

<u>Option C:</u> Coefficients are defined as the numbers which are written in front of the atoms or molecules in a chemical reaction. They represent the number of moles of substance in a chemical reaction.

<u>Option D:</u> Chemical symbols are used to write the short form of the elements.

Hence, the correct answer is Option B.

Answer:

First start with the ones we know

Explanation:

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3.dna- is all the chromosomes (genetic material)

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell

a pair - so must be bigger than one chromosome

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3. homologus pair

4.dna- is all the chromosomes (genetic material)

now 5.

A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes.

Using the periodic table, choose the more reactive nonmetal.<br> Br or As
raketka [301]

Reactivity of non-metals depend on their ability to gain electrons. So, smaller is the size of a non-metal more readily it will attract electrons because then nucleus will be more closer to valence shell. ... Hence, Br is the non-metal which will be more reactive than At.

Alenkasestr [34]

Answer:

A

Explanation:

Nitrogen is an atom made up of 7 electrons.

To draw the orbital energy level diagram, let us write the orbital notation of the atom;

  7 electrons of Nitrogen:

        1s² 2s² 2p³

So,

 The orbital notation diagram is :

            1s²         2s²          2p³
