Answer the following question given this paragraph: Consider the ramp in Figure below . It's easier to push the heavy piece of furniture up the ramp to the truck than to lift it straight up off the ground. However, pushing the furniture over the surface of the ramp creates a lot of friction. Some of the force applied to moving the furniture must be used to overcome the friction. It would be more efficient to use a dolly on wheels to roll the furniture up the ramp. That's because rolling friction is much less than sliding friction. As a result, the efficiency of the ramp would be greater with a dolly. Q: What does pushing an object over the surface of a ramp cause? A:
****
A: friction

Answer the following question given this paragraph: Genes that are located on the same chromosome are called linked genes . Alleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-over occurs when two homologous chromosomes exchange genetic material during meiosis I. The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over. At the following link, you can watch an animation showing how genes on the same chromosome may be separated by crossing-over: http://www. biostudio. com/d_%20Meiotic%20Recombination%20Between%20Linked%20Genes. htm . Q: Linked genes are located on the same what? A:
OPTIONS:
- genome
- nucleolus
- bacterium
- chromosome
chromosome

Answer the following question given this paragraph: Many enzymes are simple proteins consisting entirely of one or more amino acid chains. Other enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme's proper functioning. There are two types of cofactors: inorganic ions [e. , zinc or Cu(I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. Q: Many enzymes are simple proteins consisting entirely of one or more of these? A:
OPTIONS:
- alkali acid chains
- interaction acid chains
- proteins acid chains
- amino acid chains

Answer: amino acid chains
