Answer:
b. complementary proteins
Explanation:
Complementary proteins are proteins that contain all adequate amounts of the essential amino acids when two or more protein sources that are deficient or low in some amino acids are combined together to compensate for the deficiency of the other. The protein sources can be eaten together in a meal or consumed the same day to get a complete protein.
For example, grains are deficient in lysine, while legumes are usually deficient in methionine. Combination of rice which is a grain, together with beans which is a legume, would give us complementary protein diet, making it a complete protein source with all adequate essential amino acids available.
Answer:
Chick with in the egg depend for all its energy and food requirement on the egg yolk , therefore egg yolk is rich in fat, protein, and cholesterol.
Explanation:
Before the egg breaks and the chick comes out, few days nourishment for chicks is required. Hence, the egg yolk needs to be nutritious as new developing chick (with in the egg) rely for essential nutrients (required for growth) on the egg yolk. Chick require energy from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers
Answer: neutral
Explanation: The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
The advantages of sexual reproduction:
•Produces genetic variation in the offspring
•The species can adapt to new environments due to variation, which gives them a survival advantage
•A disease is less likely to affect all the individuals in a population
