Which foods would not make a complement of 20 amino acids, to make a complete protein?
a. corn and beans
b. brown rice and peas
c. peanut butter and white bread
d. yogurt and walnuts

Yogurt and walnut

Explanation:

Yogurt and walnut combined cannot be used as a source of 20 amino acids as yogurt is rich in protein but walnut is rich in fat. It does not contain any amino acid and is rich in vitamins and minerals.

A complete protein rich diet is a diet which includes all the 20 amino acids in it. The amino acid lacking in one food is compensated by another food.

But here, in a combination of yogurt and amino acids the yogurt is a rich source of protein but walnut is a rich source of fat only.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
