Answer:
Because the gametes implemented in fertilisation are haploid in nature, in the case of humans, mature gametes contain 23 chromosomes instead of 46 which will then combine with another parents' 23 chromosomes during fertilisation, i.e: 23 (dad) + 23 (mom) = 46 (zygote)
Explanation:
A regular somatic cell has 46 chromosomes, 2n, 2 alleles but the gametes have 23 chromomes, n, 1 allele. The usual significance of this is so that there is diversity in the offspring and the offspring can gain characteristics (bad or good) from both parents.
Answer:
Explanation:
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending to the relevant chemical formula.
Answer:
Air Pressure
Explanation:
The weight of the air that pushes down on us is air pressure, and air pressure changes depending on where you are.
These are similar because they both included desired characteristics. They are different because artificial selection has to do with humans being involved. where natural selection is with out humans being involved and is life or death.
