1. a vitamin c deficiency is characterized by:

a. easy bruising and pinpoint hemorrhages
b. cracked and bleeding lips
c. fevers and infections
d. neurological disorders

1. which of the following lunches are good sources of vitamin c?

a. tuna sandwich, tomato soup and strawberries
b. hamburger, fries and coke
c. hot dog, milk shake and cookies
d. roast beef, mashed potato, and tossed salad

Explanation:

• For question 19: Vitamin C is crucial for collagen synthesis. Collagen is important for blood vessel integrity. A deficiency leads to fragile blood vessels, causing easy bruising and pinpoint hemorrhages. Cracked and bleeding lips are more related to B - vitamin deficiencies (like riboflavin). Fevers and infections are a general sign of immune system issues (not specific to vitamin C deficiency in isolation). Neurological disorders are not a primary symptom of vitamin C deficiency.
• For question 20: Tomatoes and strawberries are rich in vitamin C. Tuna is a good source of protein. In option b, hamburger, fries, and coke are high in fat, salt, and sugar with little vitamin C. Option c (hot dog, milk - shake, cookies) is also low in vitamin C. Option d (roast beef, mashed potato, tossed salad) has some nutrients but less vitamin C compared to option a (tomato soup and strawberries are significant vitamin C sources).

Answer:

1. A. easy bruising and pinpoint hemorrhages
2. A. tuna sandwich, tomato soup and strawberries
