Simplifying things greatly (as this guide aims to do, mostly), quantum dots are incredibly small particles. They range between 2 to 10 nanometers in diameter, which is equivalent to 50 atoms. Yes, atoms. You can't measure these things using your old school shatter proof ruler. It's this small size that gives quantum dots the unique properties to improve our tech.
A zygote is formed when the male gamete (sperm) fuses with the female gamete (ova). Each gamete (regardless of the sex) is marked with an n; indicating it to be a haploid. Therefore; sperm (n) + ova (n) = zygote (2n) [A zygote is a diploid; 2n]. n = 23 chromosomes.
Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome.Sex Chromosomes: In human sexual reproduction, two distinct gametes fuse to form a zygote.Gametes are reproductive cells produced by a type of cell division called meiosis.he sex chromosomes are the X chromosome and the Y chromosome.
