Answer:
Half of the gametes carry one allele of a chromosome, and the other half carry the other allele.Then, fertilization of an egg by a sperm creates a new individual that now possesses two factors for each trait, just like the parents.
Explanation:
The female gamete is called ova which bear 'XX' chromosome and the male gamete is called as sperm that contain 'XY' chromosome.
Fertilization means the fusion of male gamete with the female gamete, which occurs at the ampulla of fallopian tube.This causes formation of zygote which bear haploid cells.
During fertilization, the sperm is capacitated and is attracted towards progesterone which contain CatSper receptor and helps in increase intracellular calcium level.
The tail of sperm disintegrates after the entry of sperm towards the cytoplasm and cortical reaction takes place.Zygote formation takes place after fusion of perm with the ova.
The sperm undergo capacitation that increase the motility and membrane destabilization occurs.
There are some basic characteristics which are used to determine if a thing is living or non living, the characteristics are 7 in all, they are: movement, nutrition, respiration, excretion, growth reproduction and sensitivity. Also, all living things are made up of cells, they have different level of organisation, they use energy and they adapt to their environment. Every thing that possess these features are considered to be living things.
Anorexic individuals have trouble maintaining normal body temperature because of the loss of body fat as insulation and lack of appropriate weight-loss strategy.
Anorexia nervosa patients (ANs) have significantly lower core temperatures (T-core) compared to healthy controls (HCs). This reduced temperature represents a reset T-core that needs to be maintained.
The development of anorexia nervosa (AN) is attributed to psycho-social causes. Anorexic individuals have night sweats because the low body weight interrupts the body's normal hormonal functions, which may halt ovulation. Excessive exercise and stress can cause similar problems.
It also effects the body if a person with anorexia becomes severely malnourished, every organ in the body can be damaged, including the brain, heart and kidneys. This damage may not be fully reversible, even when the anorexia is under control.

Answer:
Genes on chromosomes
Explanation:
It has been conclusively established that chromosomes contain the hereditary material or factors that are transmitted from parent to offspring. These factors are called genes. A gene is a short portion of a DNA molecule and is chemical in nature. A gene codes for a specific protein by specifying the order in which the amino acids are linked together.
