Answer the following question given this paragraph: Starches are complex carbohydrates. They are polymers of glucose. They consist of hundreds of glucose monomers bonded together. Plants make starch to store extra sugars. Consumers get starch from plants. Common sources of starch in the human diet are pictured in Figure below . Our digestive system breaks down starch to simple sugars, which our cells use for energy. Q: Our digestive system breaks down starch to what? Choices: - Salts - Waste - pattern sugars - simple sugars A:
simple sugars

Answer the following question given this paragraph: The Prokaryotic Cell Recall that prokaryotes (Figure 22.10) are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus but instead generally have a single chromosomea piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane. Q: Prokaryotic cells do not have a nucleus but instead generally have a single chromosome, a piece of double-stranded dna located in an area of the cell called the what? Choices: - lysosome - cytoplasm - spicule - nucleoid A:
(Answer)
nucleoid
Ques: Answer the following question given this paragraph: Sperm cells are the only human cell with flagella . This is because of their need to "swim" long distances to reach an egg for fertilization. Q: What is the only human cell with flagella? Choices: - egg - saliva - Feces - sperm A:
Ans: sperm
(Q).
Answer the following question given this paragraph: Use an electron microscope. This instrument has a resolution many times greater than a light microscope, and can be used to see the details on the outside of a cell. Some electron microscopes can also be used to see the details inside a cell. Q: What instrument has a resolution many times greater than a light microscope, and can be used to see the details on the outside of a cell? Choices: - complex microscope - element microscope - molecular microscope - electron microscope A:
(A).
electron microscope
Ques:Answer the following question given this paragraph: Because the heat is absorbed by the system, the 177.8 kJ is written as a reactant. The heat of reaction is positive for an endothermic reaction. Q: Is the heat of reaction positive or negative for an endothermic reaction? Choices: - Neither - Both - Negative - positive A:

Ans:positive
Ques:Answer the following question given this paragraph: Mass spectrometry today is used extensively in chemistry and biology laboratories to identify chemical and biological substances according to their mass-to-charge ratios. In medicine, mass spectrometers are used to measure the concentration of isotopes used as tracers. Usually, biological molecules such as proteins are very large, so they are broken down into smaller fragments before analyzing. Recently, large virus particles have been analyzed as a whole on mass spectrometers. Sometimes a gas chromatograph or high-performance liquid chromatograph provides an initial separation of the large molecules, which are then input into the mass spectrometer. Q: Mass spectrometry today is used extensively in chemistry and biology laboratories to identify chemical and biological substances according to their ratios of what? Choices: - ph to charge - volume to charge - mass to volume - mass-to-charge A:

Ans:
mass-to-charge
