Answer the following question given this paragraph: Q: Scientists often classify or organize different objects based on their what? Choices: - experimental properties - behavioral traits - independent variables - physical properties A:
physical properties
Answer the following question given this paragraph: Segmented worms have a well-developed body cavity filled with fluid. This fluid-filled cavity serves as a hydroskeleton , a supportive structure that helps move the worm's muscles. Only the most primitive worms (the flatworms) lack a body cavity. Q: What is the name of the supportive structed that helps move a worm's muscles? Choices: - spongin - exoskeleton - pollenation - hydroskeleton A:
hydroskeleton
Q: Answer the following question given this paragraph: Figure 3.7 Sucrose is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond. In the process, a water molecule is lost. By convention, the carbon atoms in a monosaccharide are numbered from the terminal carbon closest to the carbonyl group. In sucrose, a glycosidic linkage is formed between carbon 1 in glucose and carbon 2 in fructose. Q: What is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond? Choices: - fructose - sulfate - chloride - sucrose A:
A: sucrose
Question: Answer the following question given this paragraph: Bond lengths are intermediate between covalent single bonds and covalent double bonds. Q: Bond lengths are intermediate between covalent single bonds and what? Choices: - trivalent bonds - wavefunction double bonds - gravitational double bonds - covalent double bonds A:
Answer: covalent double bonds

Answer the following question given this paragraph: Extracellular Matrix of Animal Cells Most animal cells release materials into the extracellular space. The primary components of these materials are proteins, and the most abundant protein is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. Collectively, these materials are called the extracellular matrix (Figure 4.27). Not only does the extracellular matrix hold the cells together to form a tissue, but it also allows the cells within the tissue to communicate with each other. How can this happen?. Q: The extracellular matrix of most animal cells contains abundant amounts of what protein, which helps hold things together? Choices: - actin - elastin - keratin - collagen A:
**Answer**
collagen
Q: Answer the following question given this paragraph: In alcoholic fermentation, glycolysis is followed by a step that produces alcohol and carbon dioxide. This step also forms additional molecules of ATP. It occurs in yeast, such as the yeast in bread. Carbon dioxide from alcoholic fermentation creates gas bubbles in bread dough. The bubbles leave little holes in the bread after it bakes. You can see them in the bread in Figure below . The holes make the bread light and fluffy. Q: Bubbles in bread dough are created by what gas produced during alcoholic fermentation? Choices: - acid dioxide - combustion dioxide - yeast dioxide - carbon dioxide A:
A: carbon dioxide
