Q: What term is used to describe the transfer of thermal energy by particles moving through a fluid? Read this paragraph and choose the correct option from the provided answers: Convection is the transfer of thermal energy by particles moving through a fluid. Thermal energy is always transferred from an area with a higher temperature to an area with a lower temperature. Choices: - condensation - diffusion - evaporation - convection A:
convection

Q: What happens to an animal's telomeres as it ages? Read this paragraph and choose the correct option from the provided answers: As cells divide, their chromosomes get shorter. This is because the telomeres, the DNA sequences at both ends of a chromosome, lose material every time the DNA is replicated. The older the animal is, the shorter its telomeres will be, because of the number of cell cycles the cells have been through This is a natural part of aging. So, what happens to the clone if its transferred nucleus is already fairly old? Will the shortened telomeres affect its development or lifespan? The answer is still unclear. But starting a new organisms with "old" DNA with shortened telomeres is bound to have some effects, at least in some clones. Some cloned animals may be affected, others may not. Dolly the sheep's chromosomes did have shorter telomere lengths than normal. This means that Dolly's cells were aging faster than the cells from a normal sheep. Choices: - divide - lengthen - multiply - shorten A:
shorten

Q: Red-green colorblindness is an example of what kind of trait? Read this paragraph and choose the correct option from the provided answers: One example of a sex-linked trait is red-green colorblindness. People with this type of colorblindness cannot tell the difference between red and green. They often see these colors as shades of brown ( Figure below ). Boys are much more likely to be colorblind than girls ( Table below ). This is because colorblindness is a sex-linked, recessive trait. Choices: - dominant - fatal - adaptive - sex-linked A:
sex-linked
