Question

1. You discovered a new organism unknown to science. As you are dissecting it, you notice that the digestive track is relatively short with very small or reduced additional chambers. What diet do you hypothesize this organism has? (pick one)

a. Onmivore

b. Carnivore

c. Herbivore

d. Cannot determine

---------------------------

2. What are the two main functions of keeping the stomach highly aciidc? (choose TWO)

a. Increasing the absorption of carbohydrates

b. Help breakdown complex lipids mlecules

c. Denature proteins to ease their breakdown

d. Kill bacteria to prevent food borne disease.

e. Assist in the brekadown of starch

Answer 1

Long digestive tracts are often found in herbivore organisms. Omnivore have a relatively short digestive tract.

Carnivires have the shortest digestive tract with small or reduced additional chambers.

So the newly discovered organisms is having a diet as of carnivore.

2. The stomach maintains a high acidic environment inside it to kill away the bacterias and to denature proteins to ease in their digestion.

Lipid molecules are emulsified by bile salts. Starch breakdown is assisted by action of salivary amylase and enzymes present in duodenum. Absorption of carbohydrates is assisted by sodium/ potassium channels present in small intestine.
