Answer to Question 1

Familial association studies involve an analysis of shared traits or disorders among family members based on their degree of kinship, or relation. For example, in examining a family tree, one might discover that the more closely related people are, the more likely they are to have a particular trait. These studies provide supportive evidence of genetic contributions to traits or disorders. Twin studies involve the analysis of difference in the rates of overlap (or concordance) for a given trait or disorder between identical and fraternal twins. These studies provide strong evidence of genetic factors when concordance rates are higher among identical than fraternal twins. Adoptee studies involve the analysis of similarity in traits or disorders between adoptees and their biological and adoptive parents or between identical twins raised apart versus together. This is the clearest way to establish the role of heredity versus environment. If concordance is greater with traits or disorders exhibited by the adoptive parents, environmental influences are indicated. If concordance is greater with traits or disorders exhibited by the biological parents, genetic factors are indicated. These studies may not control for the effects of common environmental factors, such as shared environments shortly after birth or ongoing relationships between the twins.

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
