Answer the following question given this paragraph: The dipeptide has a free amino group on one end of the molecule and a free carboxyl group on the other end. Each is capable of extending the chain through the formation of another peptide bond. The particular sequence of amino acids in a longer chain is called an amino acid sequence. By convention, the amino acid sequence is listed in the order such that the free amino group is on the left end of the molecule and the free carboxyl group is on the right end of the molecule. For example, suppose that a sequence of the amino acids glycine, tryptophan, and alanine is formed with the free amino group as part of the glycine and the free carboxyl group as part of the alanine. The amino acid sequence can be easily written using the abbreviations as Gly-Trp-Ala. This is a different sequence from Ala-Trp-Gly because the free amino and carboxyl groups would be on different amino acids in that case. Q: What is the particular sequence of amino acids in a longer chain called? Choices: - atomic sequence - molecular sequence - carbon sequence - amino acid sequence A:
amino acid sequence
Answer the following question given this paragraph: acid will form a homogeneous solution with water. (In fact, the solubility of both butanol and pentanoic acid in water is quite low, only about 3 g per 100 g water at 25C. ) 10. An electrolyte is any compound that can form ions when it dissolves in water. When a strong electrolyte dissolves in water, it dissociates completely to give the constituent ions. In contrast, when a weak electrolyte dissolves in water, it produces relatively few ions in solution. Q: What is a compound that can form ions when it dissolves in water called? Choices: - sulfate - compound - isolate - electrolyte A:
electrolyte
Q: Answer the following question given this paragraph: The canister on the left contains a gas at a certain pressure. The attached air pump is then used to double the amount of gas in the canister. Since the canister cannot expand, the increased number of air molecules will strike the inside walls of the canister twice as frequently as they did before. The result is that the pressure inside the canister doubles. As you might imagine, if more and more air is continually added to a rigid container, it may eventually burst. Reducing the number of molecules in a rigid container has the opposite effect and the pressure decreases. Q: Reducing the number of molecules in a rigid container causes what to decrease? Choices: - velocity - demand - energy - pressure A:
A: pressure
Question: Answer the following question given this paragraph: Experiments are sometimes hard or even impossible to do. For example, a scientist who is studying an extinct animal cannot experiment with the animal because it no longer exists. The scientist must rely instead on evidence in the natural world, such as fossils that the extinct animal left behind. Q: What can be hard or even impossible to perform in a scientific sense? Choices: - hypothesises - idea - theorys - experiments A:
Answer: experiments

Answer the following question given this paragraph: Look at the skateboarders in Figure below . When they push against each other, it causes them to move apart. The harder they push together, the farther apart they move. This is an example of Newton's third law of motion. Q: When two skateboarders push against each other what happens? Choices: - they stick together - they rise - they magnetize - they move apart A:
**Answer**
they move apart
(Q).
Answer the following question given this paragraph: Gain-of-function mutations result in the gene product or protein having a new and abnormal function and usually result in a dominant phenotype. Examples of gain of function mutations occur in the thyroid hormone receptor gene. Q: What phenotype do gain-of-function mutations usually result in? Choices: - submissive - internal - external - dominant A:
(A).
dominant
