Answer the following question given this paragraph: Gram-negative bacteria have a cell wall made of peptidoglycan, whereas Gram-positive bacteria have a cell wall made of lipoteichoic acid. Figure 22.19 Which of the following statements about the nitrogen cycle is false? a. Nitrogen fixing bacteria exist on the root nodules of legumes and in the soil. Denitrifying bacteria convert nitrates (NO3-) into nitrogen gas (N2). Ammonification is the process by which ammonium ion (NH4+) is released from decomposing organic compounds. Nitrification is the process by which nitrites (NO2-) are converted to ammonium ion (NH4+). Q: Gram-negative bacteria have a cell wall made of peptidoglycan, whereas gram-positive bacteria have a cell wall made of what? Choices: - choanocyte acid - solmization acid - hydrolic acid - lipoteichoic acid A:
lipoteichoic acid

Answer the following question given this paragraph: There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic. One occurs in the presence of oxygen ( aerobic ), and one occurs in the absence of oxygen ( anaerobic ). Both begin with glycolysis - the splitting of glucose. Q: What type of cellular respiration occurs in the presence of oxygen? Choices: - hyperbaric - anaerobic - extracellular - aerobic A:
aerobic

Answer the following question given this paragraph: What if you want a different approach? Let's say you don't want to wrap a flat piece of paper around a round object. You could put a flat piece of paper right on the area that you want to map. This type of map is called a gnomonic map projection ( Figure below ). The paper only touches Earth at one point. The sizes and shapes of countries near that point are good. The poles are often mapped this way to avoid distortion. A gnomic projection is best for use over a small area. Q: What type of map projection is used for small areas to avoid distortion? Choices: - unmeasured projection - mercator projection - equatorial projection - gnomic projection A:
gnomic projection

Answer the following question given this paragraph: Q: What type of tissue runs the length of a stem in vascular bundles? Choices: - thermal tissue - muscle tissue - cardiac tissue - vascular tissue A:
vascular tissue
