Answer:
b. 2N meiosis 1N fertilization 2N
Explanation:
In eukaryotic organisms, gamete mother cells are diploid (2N) and have two complete sets of chromosomes. Meiosis in male and female gamete mother cells form haploid male and female gametes (N) respectively. This occurs since meiosis reduces the number of the chromosome to half in the daughter cells. The fusion of haploid male and female gametes during fertilization restores the diploid chromosome number of the species and forms diploid zygote (2N). Repeated mitotic divisions in the diploid zygote form the diploid organism.
Answer:
The correct answer is BB genotype and BO genotype.
Explanation:
The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).
If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.
Thus, the correct answer is the BB genotype and BO genotype.

Answer:
What is the chemical that helps in providing the ideal PH for pancreatic amylase to function in the human body?
Explanation:
This allows the protein lipase to break down and digest the fat in the small intestine much more quickly. The pancreas secretes bicarbonate to neutralize the acidity of chyme and pancreatic amylase to aid in the digestion of carbohydrates.
