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.
Answer:
To increase the chance of finding this species, what is suggested is to increase the number of samples evaluated in the person's microbiome. On the one hand we can increase the sample size or the number of samples of the experiment. Another possibility is to take samples from different parts of the body.
The answer is B hope it helps pls mark branliest
Answer:
Anthropogenic (human-caused) GHG emissions are modifying the Earth's energy balance between incoming solar radiation and the heat released back into space, amplifying the greenhouse effect and resulting in climate change.
Explanation:
While the natural greenhouse effect makes life possible on Earth, human activity can cause increased amounts of greenhouses gases to be produced in our atmosphere, resulting in a greenhouse effect.
