Answer the following question given this paragraph: Proteins are formed when hundreds or even thousands of amino acids form amide bonds to make polymers. Proteins play a crucial role in living organisms. A carbohydrate is a compound that has the general formula Cn(H2O)n. Many carbohydrates are relatively small molecules, such as glucose:. Q: What are proteins made up of? Choices: - lewis acids - detected acids - atoms acids - amino acids A:
amino acids

Answer the following question given this paragraph: material, and is intimately related to the polarizability of the material. Things Great and Small The Submicroscopic Origin of Polarization Polarization is a separation of charge within an atom or molecule. As has been noted, the planetary model of the atom pictures it as having a positive nucleus orbited by negative electrons, analogous to the planets orbiting the Sun. Although this model is not completely accurate, it is very helpful in explaining a vast range of phenomena and will be refined elsewhere, such as in Atomic Physics. The submicroscopic origin of polarization can be modeled as shown in Figure 19.18. Q: What process refers to a separation of charge within an atom or molecule? Choices: - diffusion - convection - rotation - polarization A:
(Answer)
polarization
Ques: Answer the following question given this paragraph: Most chromosomal disorders involve the sex chromosomes. Can you guess why? The X and Y chromosomes are very different in size. The X is much larger than the Y. This difference in size creates problems. It increases the chances that the two chromosomes will fail to separate properly during meiosis. Q: Most chromosomal disorders involve which chromosomes? Choices: - autosomes - ribosomes - protosomes - sex chromosomes A:
Ans: sex chromosomes
(Q).
Answer the following question given this paragraph: Figure 5.17 A uniporter carries one molecule or ion. A symporter carries two different molecules or ions, both in the same direction. An antiporter also carries two different molecules or ions, but in different directions. (credit: modification of work by "Lupask"/Wikimedia Commons). Q: A symporter carries how many different molecules or ions in the same direction? Choices: - one - three - four - two A:
(A).
two
Ques:Answer the following question given this paragraph: Vinegar is an acid that can be produced from the aerobic fermentation of wine. In fact, vinegar is most likely the oldest known acid. It is commonly used as a food additive (to give things an acidic or sour taste) and as a mild cleaning agent. Q: What is an acid that can be produced from the aerobic fermentation of wine? Choices: - soda - orange juice - grape juice - vinegar A:

Ans:vinegar
Answer the following question given this paragraph: Matter is all the "stuff" that exists in the universe. Everything you can see and touch is made of matter, including you! The only things that aren't matter are forms of energy, such as light and sound. In science, matter is defined as anything that has mass and volume. Mass and volume measure different aspects of matter. Q: In science, anything that has mass and volume is considered what? Choices: - renewable - visible - an element - matter A:
matter
