Ques: Q: What type of mammals are characterized by detailed development of the hands and feet, a shortened snout, and a large brain? Read this paragraph and choose the correct option from the provided answers: Primates include monkeys, apes and humans. These mammals are characterized by detailed development of the hands and feet, a shortened snout, and a large brain. Choices: - apes - amphibians - mammles - primates A:
Ans: primates

Ques: Q: What oily substance prevents the hair and skin of living things from drying out? Read this paragraph and choose the correct option from the provided answers: Sebaceous glands are commonly called oil glands. They produce an oily substance called sebum. Sebum is secreted into hair follicles. Then it makes its way along the hair shaft to the surface of the skin. Sebum waterproofs the hair and skin and helps prevent them from drying out. Choices: - pus - progesterone - pancreatic enzymes - sebum A:
Ans: sebum

Ques: Q: What type of blood cells transport oxygen to the tissues so they can function? Read this paragraph and choose the correct option from the provided answers: Red blood cells transport oxygen to the tissues so they can function. In the absence of oxygen, cells cannot carry out their biochemical responsibilities. Oxygen moves to the cells attached to hemoglobin, a protein found in the red cells. In cases of carbon monoxide poisoning, CO binds much more strongly to the hemoglobin, blocking oxygen attachment and lowering the amount of oxygen reaching the cells. Treatment involves the patient breathing pure oxygen to displace the carbon monoxide. The equilibrium reaction shown below illustrates the shift toward the right when excess oxygen is added to the system:. Choices: - white blood cells - mutated blood cells - depleted blood cells - red blood cells A:
Ans: red blood cells

Ques: Q: The two smallest carboxylic acids are formic acid and what else? Read this paragraph and choose the correct option from the provided answers: The two smallest carboxylic acids are formic acid (found in the stingers of ants) and acetic acid (found in vinegar). Many organic compounds are considerably more complex than the examples described here. Many compounds, such as cholesterol discussed in the chapter-opening essay, contain more than one functional group. The formal names can also be quite complex. In http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gobch12through http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch15, we will examine the characteristics and chemistry of other important organic compounds and functional groups. Choices: - carbonates acid - ethylene acid - ascorbic acid - acetic acid A:
Ans:
acetic acid
