Question: Answer the following question given this paragraph: Steroid Hormones The primary hormones derived from lipids are steroids. Steroid hormones are derived from the lipid cholesterol. For example, the reproductive hormones testosterone and the estrogenswhich are produced by the gonads (testes and ovaries)are steroid hormones. The adrenal glands produce the steroid hormone aldosterone, which is involved in osmoregulation, and cortisol, which plays a role in metabolism. Like cholesterol, steroid hormones are not soluble in water (they are hydrophobic). Because blood is water-based, lipidderived hormones must travel to their target cell bound to a transport protein. This more complex structure extends the half-life of steroid hormones much longer than that of hormones derived from amino acids. A hormone's half-life is the time required for half the concentration of the hormone to be degraded. For example, the lipid-derived hormone cortisol has a half-life of approximately 60 to 90 minutes. In contrast, the amino acidderived hormone epinephrine has a half-life of approximately one minute. Q: The primary hormones derived from lipids are what? Choices: - amino acids - melatonins - antibiotics - steroids A:
Answer: steroids

Question: Answer the following question given this paragraph: Polymers are a pervasive part of modern life. It is very likely that at least some part of your clothing is made of nylon, rayon, or polyester. The milk or juice that you have for breakfast often comes in a polyethylene container. If you don't have breakfast at home, you might get coffee from a fast food establishment, where your order is delivered to you in a Styrofoam®️ container. While getting out of your car, you bang the door on another vehicle. One reason you may not have dented the door is the fact that it could be made out of a polymeric plastic material that resists deformation more than simple metallic structures. Elsewhere on your car, both synthetic and natural rubber are probably present in the tires. All these materials are examples of organic polymers. Q: Synthetic and natural rubber, styrofoam and plastic are examples of organic what? Choices: - solutions - microbes - metals - polymers A:
Answer: polymers

Question: Answer the following question given this paragraph: Crocodilia Reptiles in the Crocodilia Order are called crocodilians. They include crocodiles, alligators, caimans, and gharils. They have four sprawling legs that allow them to run surprisingly fast. They have strong jaws and replace their teeth throughout life. Crocodilians have relatively complex brains and greater intelligence than other reptiles. crocodile. Q: The crocodilia order, which includes crocodiles, alligators, caimans, and gharils, is part of what class of animals? Choices: - aquatic - mammals - parasites - reptiles A:
Answer:
reptiles
