Answer 1

Answer:

a.) Small intestine

b.) Pseudopodia

c.) Villi

d.) Food vacuole

e.) Simpler and absorbable food molecules

f.) Mouth (buccal cavity)

g.) Saliva (and pancreatic juice, but in small amounts)

h.) Defecation (This is the name for excretion of feces. I don't know name for formation of feces.)

i.) Stomach

j.) Egestion/excretion

Explanation:

a.) Complete digestion of food takes in small intestine. (In large intestine, only water and nutrients are absorbed from leftover food/chyme.)

b.) In amoeba and paramecium, simple engulfing or catching occurs with the help of pseudopodia. (They have false feet/pseudopodia, which when extended turn into "arms" which can grab food to engulf.)

c.) The inner wall of the small intestine has many finger-like outgrowths called villi. (Villi are tiny, finger-like projections made up of cells that line the entire length of your small intestine. They absorb nutrients from the food you eat and then shuttle those nutrients into your bloodstream so they can travel where they're needed.)

d.) Amoeba digests its food in the food vacuole. (After engulfing the food, it transfers it to its food vacuole where food is digested with the help of enzymes.)

e.) Digestion is the breakdown of complex food materials into simpler and absorbable food molecules. (It breakdowns large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.)

f.) Digestion of starch starts in mouth (buccal cavity). (Salivary glands in the mouth secrete saliva, which helps to moisten the food. The food is then chewed while the salivary glands also release the enzyme salivary amylase, which begins the process of breaking down the carbohydrate food.)

g.) The enzyme amylase is present in saliva (and pancreatic juice, but in small amounts). (Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands. It comprises a small portion of the total amylase excreted, which is mostly made by the pancreas.)

h.) EXCRETION of feces is called defecation. (I really don't think there is a name for formation of feces.)

i.) Killing of bacteria is done in stomach. (In stomach, HCl (hydrochloric acid) is present which is highly acidic (ph = 2-4). It kills the bacteria which come with food.)

j.) The main steps of digestion in humans are ingestion, digestion, absorption, assimilation and egestion/excretion. (Ingestion: Intake of food.

Digestion: Breaking down of food so that it can be absorbed by the body.

Absorption: The process of absorbing food in the form of nutrients into the blood stream of the body.

Assimilation: The process of nutrients being absorbed by each cell of the body in the form of energy.

Egestion/excretion: Process of voiding or discharging undigested food as feces. To egest means to discharge undigested material or food.)
