Answer to Question 1

A direct relationship will slope upward; it will have a positive slope. An inverse relationship will slope downward; it will have a negative slope. A change in some relevant variable other than those listed on the vertical or horizontal axis must change in order to shift a line or curve expressing a relationship between two variables.

Answer to Question 2

A direct relationship between two variables means an increase in the value of the independent variable will cause an increase in the value of the dependent variable; and vice versa. An example would be the relationship between the selling price of a good and the amount of the good put up for sale by producers. An inverse relationship between two variables means an increase in the value of the independent variable will cause a decrease in the value of the dependent variable; and vice versa. An example would be the relationship between the price of a good and the amount purchased.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
