Answer:
a. Salivary amylase
b. Mouth
c. Stomach
d. S cells of the small intestinal crypts of Lieberkhün
Explanation:
Carbohydrate digestion begins with salivary amylase in the mouth.
This enzyme hydrolyzes to produce maltose, oligosaccharides, and glucose for around 1–2 hours before it is deactivated in the stomach. When chyme reaches the duodenum, the S cells of the small intestinal crypts of Lieberkhün is stimulated to produce even larger quantities of this enzyme to continue digestion.
Answer:
dynamic equilibrium is the answer.
Dynamic - motion
Equilibrium - no net change
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
Answer:
autosomal dominant, affected
Explanation:
Neurofibromatosis is an autosomal (non-sex chromosome) dominant disease, which means that a <u>single mutant gene from the parents can cause the disease in the next generation</u>. And there is a 50% chance of passing the affected genes to the children.
In this case, since we know the mother does not carry the mutant allele, and just one copy of the affected allele is enough for the children to have neurofibromatosis. We can conclude that the father carries the mutant allele and 3 of the 5 children, inherited the afected allele and have the disease.
