Ques: Answer the following question given this paragraph: Figure 3.19 A phospholipid is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone. The phosphate may be modified by the addition of charged or polar chemical groups. Two chemical groups that may modify the phosphate, choline and serine, are shown here. Both choline and serine attach to the phosphate group at the position labeled R via the hydroxyl group indicated in green. Q: What is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone? Choices: - carbohydrate - polymer - amino acid - phospholipid A:
Ans: phospholipid
(Q).
Answer the following question given this paragraph: Although neon has just one more electron than fluorine in its outer energy level, that one electron makes a huge difference. Fluorine needs one more electron to fill its outer energy level in order to have the most stable arrangement of electrons. Therefore, fluorine readily accepts an electron from any element that is equally "eager" to give one up, such as the metal lithium or sodium. As a result, fluorine is highly reactive. In fact, reactions with fluorine are often explosive, as you can see in the URL below. Neon, on the other hand, already has a full outer energy level. It is already very stable and never reacts with other elements. It neither accepts nor gives up electrons. Neon doesn't even react with fluorine, which reacts with all other elements except helium. Q: Which has more electrons, neon or fluorine? Choices: - the same - fluorine - neither - neon A:
(A).
neon
Ques:Answer the following question given this paragraph: Q: What are the outpocketings of the digestive tract that remove nitrogenous wastes and function in osmoregulation? Choices: - olivary tubules - integumentary tubules - intestinal tubules - malpighian tubules A:

Ans:malpighian tubules
Ques:Answer the following question given this paragraph: The atmosphere is a thin layer of gas that surrounds Earth. Climatologists study the atmosphere. These scientists work to understand the climate as it is now. They also study how climate will change in response to global warming. Q: What is a thin layer of gas that surrounds earth called? Choices: - the cloud cover - the dioxide - the wind cycle - the atmosphere A:

Ans:
the atmosphere
