Answer the following question given this paragraph: When was the last time you enjoyed yogurt on your breakfast cereal, or had a tetanus shot? These experiences may appear unconnected, but both relate to bacteria which do not use oxygen to make ATP. In fact, tetanus bacteria cannot survive if oxygen is present. However, Lactobacillus acidophilus (bacteria which make yogurt) and Clostridium tetani (bacteria which cause tetanus or lockjaw) share with nearly all organisms the first stage of cellular respiration, glycolysis ( Figure below ). Because glycolysis is universal, whereas aerobic (oxygen-requiring) cellular respiration is not, most biologists consider it to be the most fundamental and primitive pathway for making ATP. Q: What is the first stage of cellular respiration called? Choices: - appetite - reproduction - photosynthesis - glycolysis A:
glycolysis

Answer the following question given this paragraph: The chapter describes thermal energy, radiant energy, electrical energy, nuclear energy, and chemical energy. Which form(s) of energy are represented by each of the following?. Q: Thermal, radiant, electrical, nuclear, and chemical are all types of what? Choices: - fuel - fuel - heating - energy A:
(Answer)
energy
Ques: Answer the following question given this paragraph: In eukaryotic cells, most of the intracellular proteins that are activated by a ligand binding to a receptor protein are enzymes. Receptor proteins are named after the type of enzyme that they interact with inside the cell. These enzymes include G proteins and protein kinases, likewise there are G-protein-linked receptors and tyrosine kinase receptors. A kinase is a protein involved in phosphorylation. Tyrosine kinase receptors bind many polypeptide growth factors, cytokines, and hormones. Once the ligand is bound, these receptors specifically phosphorylate tyrosine amino acids, activating the signal transduction process inside the cell. Q: What is named after the type of enzyme they interact with in the cell? Choices: - oxygen proteins - function proteins - nitrogen proteins - receptor proteins A:
Ans: receptor proteins

half
Ques:Answer the following question given this paragraph: Gamma rays can destroy living cells, produce mutations, and cause cancer. They can be used to treat cancer by focusing the deadly rays on cancer cells. Q: What can destroy living cells, produce mutations and cause cancer? Choices: - plasma rays - stingrays - prismatic rays - gamma rays A:

Ans:gamma rays
Answer the following question given this paragraph: Refraction is responsible for dispersion in rainbows and many other situations. The angle of refraction depends on the index of refraction, as we saw in The Law of Refraction. We know that the index of refraction n depends on the medium. But for a given medium, n also depends on wavelength. (See Table 25.2. Note that, for a given medium, n increases as wavelength decreases and is greatest for violet light. Thus violet light is bent more than red light, as shown for a prism in Figure 25.23(b), and the light is dispersed into the same sequence of wavelengths as seen in Figure 25.21 and Figure 25.22. Making Connections: Dispersion Any type of wave can exhibit dispersion. Sound waves, all types of electromagnetic waves, and water waves can be dispersed according to wavelength. Dispersion occurs whenever the speed of propagation depends on wavelength, thus separating and spreading out various wavelengths. Dispersion may require special circumstances and can result in spectacular displays such as in the production of a rainbow. This is also true for sound, since all frequencies ordinarily travel at the same speed. If you listen to sound through a long tube, such as a vacuum cleaner hose, you can easily hear it is dispersed by interaction with the tube. Dispersion, in fact, can reveal a great deal about what the wave has encountered that disperses its wavelengths. The dispersion of electromagnetic radiation from outer space, for example, has revealed much about what exists between the starsthe so-called empty space. Q: The angle of refraction depends on the index of what? Choices: - frequency - vibration - reflection - refraction A:
refraction
