Ques:Answer the following question given this paragraph: Figure 42.10 An antigen is a macromolecule that reacts with components of the immune system. A given antigen may contain several motifs that are recognized by immune cells. Each motif is an epitope. In this figure, the entire structure is an antigen, and the orange, salmon and green components projecting from it represent potential epitopes. Q: An antigen is a macromolecule that reacts with components of what? Choices: - circulatory system - pulmonary system - digestion system - immune system A:

Ans:immune system
Ques:Answer the following question given this paragraph: Dermal tissue covers the outside of a plant in a single layer of cells called the epidermis. You can think of the epidermis as the plant's skin. It mediates most of the interactions between a plant and its environment. Epidermal cells secrete a waxy substance called cuticle , which coats, waterproofs, and protects the above-ground parts of plants. Cuticle helps prevent water loss, abrasions, infections, and damage from toxins. Q: What is the waxy substance that epidermal cells secrete? Choices: - cellulose - bile - saliva - cuticle A:

Ans:
cuticle
