Answer the following question given this paragraph: The last step in a scientific investigation is communicating what you have learned with others. This is a very important step because it allows others to test your hypothesis. If other researchers get the same results as yours, they add support to the hypothesis. However, if they get different results, they may disprove the hypothesis. When scientists share their results, they should describe their methods and point out any possible problems with the investigation. Results can be communicated in various ways. A scientist usually contributes material through publication in a peer-reviewed scientific journal. Peer-review ensures the material is of an acceptable quality for the scientific community. Scientists also write review articles, book chapters, and even whole books. They also regularly participate in scientific meetings, presenting their material in front of large audiences of their peers. Q: What is the last step in a scientific investigation? Choices: - documenting findings - verifying findings - retesting findings - communicating findings A:
communicating findings
Answer the following question given this paragraph: Figure 29.17 The tails of the Hale-Bopp comet point away from the Sun, evidence that light has momentum. Dust emanating from the body of the comet forms this tail. Particles of dust are pushed away from the Sun by light reflecting from them. The blue ionized gas tail is also produced by photons interacting with atoms in the comet material. (credit: Geoff Chester, U. Navy, via Wikimedia Commons). Q: The tails of the hale-bopp comet point away from the sun, evidence that light has what property of motion? Choices: - inertia - velocity - acceleration - momentum A:
momentum
Q: Answer the following question given this paragraph: perpendicular to the surface at the point where the ray strikes the surface. Q: Desert plants have evolved processes to conserve water and deal with harsh conditions. a more efficient use of co2 allows plants to adapt to living with what? Choices: - less competition - more water - more sunlight - less water A:
A: less water
Question: Answer the following question given this paragraph: Q: Each nitrogenous base has one or two rings that include which atoms? Choices: - oxygen - hydrogen - carbon - nitrogen A:
Answer: nitrogen

Answer the following question given this paragraph: Epistasis is when a gene at one location (locus) alters the phenotypic expression of a gene at another locus. Epistasis takes place when the action of one gene is modified by one or several other genes. These genes are sometimes called modifier genes . The gene whose phenotype is expressed is said to be epistatic , while the phenotype that is altered is said to be hypostatic . Sometimes hypostatic phenotypes are completely suppressed. Epistatic genes are not dominant over the genes they alter or suppress. Dominance refers to an interaction between alleles of the same gene, not different genes. Q: What is it called when a gene at one location (locus) alters the phenotypic expression of a gene at another locus? Choices: - exogenous - epigenesis - spontaneous mutation - epistasis A:
**Answer**
epistasis

Answer the following question given this paragraph: Digestion and Absorption Digestion is the mechanical and chemical break down of food into small organic fragments. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across the digestive epithelium. Large, complex molecules of proteins, polysaccharides, and lipids must be reduced to simpler particles such as simple sugar before they can be absorbed by the digestive epithelial cells. Different organs play specific roles in the digestive process. Q: What process is used to chemically and mechanically break down the food you eat into smaller parts? Choices: - absorption - regression - filtration - digestion A:
(Answer)
digestion
