Nitrogen (78%) and Oxygen (21%)
Answer:
The following punnet square would be constructed from the above mentioned cross:
b b
B Bb Bb
B Bb Bb
A punnet square can be described as a diagram which is made to illustrate the outcomes of a cross.
The results from the above punnet square show that the offsprings produced from a cross between homozygous blue and brown parent, will all have blue feathers but they all will be heterozygous for the trait.
The respiratory structure that comprises a cartilage as well as the ligaments would be the trachea which is the answer. The trachea which is known as windpipe is a tube connecting pharynx and larynx into the lungs allowing the air to pass through.

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.
