Answer the following question given this paragraph: Cancer treatments vary depending on the disease's type and stage. Traditional approaches, including surgery, radiation, chemotherapy, and hormonal therapy, aim to remove or kill rapidly dividing cancer cells, but these strategies have their limitations. Depending on a tumor's location, for example, cancer surgeons may be unable to remove it. Radiation and chemotherapy are difficult, and it is often impossible to target only the cancer cells. The treatments inevitably destroy healthy tissue as well. To address this, researchers are working on pharmaceuticals that can target specific proteins implicated in cancer-associated molecular pathways. Q: Depending on a tumor's location, for example, cancer surgeons may be unable to remove it. radiation and chemotherapy are difficult, and it is often impossible to target only the cancer cells. the treatments inevitably destroy this? Choices: - carcinogens - fertility - host cells - healthy cells A:
healthy cells

Answer the following question given this paragraph: Liquid water is formed when water vapor condenses (i. e. , H 2 O(g) H 2 O(l) or when ice melts (i. e. , H 2 O(s) H 2 O(l)). Because water is a molecular substance, it is a poor conductor of electricity in its pure form. However, as we will see later, its conductivity can be improved by the addition of certain substances. Water molecules are polar, and this overall polarity gives rise to many of the properties of water. For example, an interesting effect is seen when water is placed in a static electric field, as shown in the Figure below and the video below. This phenomenon can be explained in terms of the polarity of water molecules. Q: What is type of substance is formed when water vapor condenses or when ice melts? Choices: - toxic water - chemical water - gaseous water - liquid water A:
(Answer)
liquid water

Answer the following question given this paragraph: Enzymes Enzymes, catalysts that occur naturally in living organisms, are almost all protein molecules with typical molecular masses of 20,000100,000 amu. Some are homogeneous catalysts that react in aqueous solution within a cellular compartment of an organism. Others are heterogeneous catalysts embedded within the membranes that separate cells and cellular compartments from their surroundings. The reactant in an enzyme-catalyzed reaction is called a substrate. Because enzymes can increase reaction rates by enormous factors (up to 10 17 times the uncatalyzed rate) and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research. At the same time, enzymes are usually expensive to obtain, they often cease functioning at temperatures greater than 37C, have limited stability in solution, and have such high specificity that they are confined to turning one particular set of reactants into one particular product. This means that separate processes using different enzymes must be developed for chemically similar reactions, which is time-consuming and expensive. Thus far, enzymes have found only limited industrial applications, although they are used as ingredients in laundry detergents, contact lens cleaners, and meat tenderizers. The enzymes in these applications tend to be proteases, which are able to cleave the amide bonds that hold amino acids together in proteins. Meat tenderizers, for example, contain a protease called papain, which is isolated from papaya juice. It cleaves some of the long, fibrous protein molecules that make inexpensive cuts of beef tough, producing a piece of meat that is more tender. Some insects, like the bombadier beetle, carry an enzyme capable of catalyzing the decomposition of hydrogen peroxide to water (Figure 14.28 "A Catalytic Defense Mechanism"). Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a... Q: What are the catalysts that occur naturally in living organisms and are primarily protein molecules? Choices: - carbohydrates - hormones - acids - enzymes A:
(A).
enzymes
Ques:Answer the following question given this paragraph: Photosynthesis occurs in two stages, called the light reactions and the Calvin cycle. Figure below sums up what happens in these two stages. Both stages are described below. Q: The calvin cycle and light reactions are the two stages of what process? Choices: - condensation - evaporation - cell growth - photosynthesis A:

Ans:photosynthesis
Question: Answer the following question given this paragraph: Visible light is light that has wavelengths that can be detected by the human eye. The wavelength of visible light determines the color that the light appears. As you can see in the Figure below , light with the longest wavelength appears red, and light with the shortest wavelength appears violet. In between are all the other colors of light that we can see. Only seven main colors of light are actually represented in the diagram. Q: Visible light has what that can be detected by the human eye? Choices: - patterns - dimensions - colors - wavelengths A:
Answer:
wavelengths
