C- Arctic foxes and Arctic hares grow white coats as camouflage in winter.
D- Protozoans can enter the bloodstream and multiply in the liver, causing malaria.

A

Explanation:

Bcs it’s common sense the duck and platypus looks alike same

1. antibodies

2. hormones

3. kidney stones

4. transport proteins

5. protein-energy malnutrition

6. coenzymes

7. buffer

8. kwashiorkor

Explanation:

1. ANTIBODIES are proteins that aid the immune system in its fight against bacteria, viruses, and other foreign substance by binding to them and helping to inactivate or destroy them.

2. HORMONES are substances made of protein or lipid released into the bloodstream in order to direct physiological activity in the body.

3. A high-protein diet can increase the risk of KIDNEY STONES because the body will have an increased acid level.

4. TRANSPORT PROTEINS carry many substances through the blood or allow movement of substances in and out of cells.

5. PROTEIN-ENERGY MALNUTRITION is the phenomenon used to describe an inadequate intake of proteins and/or calorie content.

6. COENZYMES are molecules that play vital roles in the function of an enzyme. Coenzyme in form of vitamins are utilized by enzymes to catalyze chemical reactions.

7. Proteins can act like BUFFER (a substance with a stable pH) in order to regulate the acid-base balance in the body.

8. KWASHIORKOR is a malnutrition deficiency that result from the insufficiency of dietary protein, resulting in swelling in the feet, legs, and stomach among other symptoms.
