During chemical digestion
a. foods are chopped and ground up and then mixed by segmentation
b. mastication, deglutition and segmentation of foods occurs
c. digestive products of macromolecular substances are transported through the mucosal into the blood/lymph
d. glycolysis, the krebs cycle and oxidative phosphorylation produce atp
e. large macromolecules are hydrolyzed into small subunits

The correct answer is option E.

Explanation:

Digestions refers to the breaking down of food (larger molecules) into smaller absorb-able units.

Chemical digestion refers to digestion of food with the help of chemicals such enzymes, acid, and bile.

Enzymes are the main type of chemicals which hydrolysis (breaking down of compound with the help of water) the macro-molecules such as polysaccharides, polypeptides, et cetera into smaller and simpler units.

For example, amylase hydrolyse polysaccharides into smaller units such as maltose and glucose; trypsin, chymotrypsin, pepsin are enzymes which hydrolyze polypeptides into amino acids, nucleases are the enzymes which help in hydrolysis of nucleic acids, et cetera.

Bile and lipases help in emulsification of fats.

Thus, the correct answer is option E.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
