Answer:

Digestive enzymes are the natural substances our body needs to help break down and digest food

We have three main digestive enzymes :

Proteases: These enzymes break down protein into small peptides and amino acids.

Lipases: break down fat into three fatty acids plus a glycerol molecule.

Amylases: Are responsible for breaking down carbs like starch into simple sugars.

Digestive enzymes are proteins that catalyze mainly hydrolysis reactions that make nutrients absorbable in the digestive tract. Pepsin is a gastric enzyme that turns proteins into albumoses and peptones which are shorter peptide chains that are then hydrolyzed to even shorter chains until amino acids by intestinal enzymes. Pancreatic amylase is an enzyme that turns starch(a polysaccharide) into maltose(a disaccharide). Lipase is present in the gastric juice, the pancreatic juice, and the intestinal juice. This enzyme catalyzes the hydrolysis of lipids(mainly triglycerides) into fatty acids and glycerol. When incomplete hydrolysis occurs triglycerides can become monoglycerides.

Serous membranes line certain cavities within the anterior body cavity. a. true b. false

crimeas [40]

Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.

Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.

An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.

1 Pterodactyl (reptile)

goldfiish [28.3K]

Answer:

Analogous structures are structures which serve similar function in different organisms and evolved independently in two living organisms while homologous structures are the structures which are similar in related orgnanism due to inheritance.

The wings of Pterodactyl, bats and birds are conisdered as analogous structure. they are similar in structure and same in function and evolved independently in the two groups of animals.

Bones in forelimbs of pterodactyl, bats and birds are considered homologous structures as they inherited the pattern from a common ancestor and have different functions.
