Explanation:

The subatomic particles in any atom are made up of protons, neutrons and electrons in it.

Protons are the positively charged particles.

Neutrons do not carry any charges.

Together with protons, they occupy the nucleus.

Electrons are negatively charged particles.

In an atom of B - 11;

11 is the mass number

mass number = number of protons + number of neutrons.

Total subatomic particles = proton + neutrons + electrons

TSP = mass number + electrons

In B, the atomic number = 5 = number of electrons

TSP = 11 + 5 = 16

Characteristics of pea plants are determined by genes inherited from both the parents.

Option 4.

<h3>Explanation:</h3>

Gregor Johann Mendel is also called as the father of Genetics. Mendel experimented on the pea plants to determine what happens when different types of pea plants are crossed between themselves and what actually determines the characteristics of the pea plants. After two types of experiments, he came to a conclusion that there are certain substances which he named as '' factors'' which are actually inherited from the parents. He also told that there are certain type of factors which are dominant over the others which he termed as recessive factors. So, the characteristics of the progenies depend on both the factors inherited from both the parents.
