ahrayia [7]

Answer:

Soil condition directly affects crop growth.

Explanation:

Soil condition affects the crop growth directly. If a soil is in fertile condition then the growth of crop which is growing in such soil will be good but if the soil is infertile then the crop will not grow to its fullest. A fertile soil is the one which has optimum condition for growth of a crop like suitable pH, moisture retention capacity, good amount of nutrients & minerals like nitrogen, phosphorus, sodium, potassium, magnesium etc. If a soil is rich in all these constituents then the crop which is growing in this soil will be healthy. But, if a soil is infertile then the crop which is growing on that soil will be under stress and will not be able to grow completely.

How can we figure out the number of electons
sweet [91]

Answer:

Subtraction of the number of protons from the mass number.

Explanation:

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is similar to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

To determine the number of neutrons in an atom, we only have to subtract the number of protons from the mass number. Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred to as mass number (Also called atomic mass).
