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? A:

OPTIONS:
- exogenous
- epigenesis
- spontaneous mutation
- epistasis

Answer: epistasis

Answer the following question given this paragraph: Figure 7.2 Axial and Appendicular Skeleton The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. It consists of the skull, vertebral column (including the sacrum and coccyx), and the thoracic cage, formed by the ribs and sternum. The appendicular skeleton is made up of all bones of the upper and lower limbs. Q: The appendicular skeleton is made up of all bones of the upper and lower what? A:
****
A: limbs

Problem:OPTIONS:
- length
- diameter
- width
- height

Answer the following question given this paragraph: Seismograms contain a lot of information about an earthquake: its strength, length, and distance. Wave height is used to determine the magnitude of the earthquake. The seismogram shows the different arrival times of the seismic waves ( Figure below ). The first waves are P-waves since they are the fastest. S-waves come in next and are usually larger than P-waves. The surface waves arrive just after the S-waves. If the earthquake has a shallow focus, the surface waves are the largest ones recorded. Q: What measurement of the wave is used to determine the magnitude of an earthquake? A:
****
A:
height
