devlian [24]
The answer is: from mother

In a human diploid somatic cell (2n), there are<span> in total 46 chromosomes</span> - 22 autosomal chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes. In males, there is one X and one Y chromosome (XY) while in females, there are two XX chromosomes (XY).
During the formation of gametes, a female could give only X chromosomes, so gametes from the mother contain one X chromosome. But, a male could give X or Y chromosome, so gametes from the father contain either X or Y chromosome.
Female gamete and male gamete fuse to form a zygote. Male zygote must contain both X and Y chromosome. It inherits Y chromosome only from the father, so X chromosome must be inherited from the mother.

Which of the following species is diamagnetic? View Available Hint(s) Hint 1. How to determine magnetism Which of the following
m_a_m_a [10]

Answer:

Explanation:

Cl = 1s2 2s2 2p6 3s2 3p5

Al = 1s2 2s2 2p6 3s2 3p1

Fe2+ = 1s2 2s2 2p6 3s2 3p6 4s2 3d4

S2- = 1s2 2s2 2p6 3s2 3p6

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. If all electrons in the particle are paired, then the substance made of this particle is diamagnetic.

S2- is diamagnetic because of its paired electrons in the outermost shell.
