Answer:
Stomach mucus protects the gastrointestinal cells from the damage that gastric juices can cause. Gastric juices are very acidic and without the mucus, the acid can destroy the cells and tissues inside the stomach.
Answer:
q = 0.2, p = 0.8
Explanation:
According to Hardy-Weinberg equilibrium,
p + q = 1
p² + 2pq + q² = 1 where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of homozygous dominant genotype
2pq = frequency of heterozygous genotype
q² = frequency of homozygous recessive genotype
Here,
q² = aa = 0.04
q = √0.04 = 0.2
p = 1 - q
= 1 - 0.2
= 0.8
