70% Answer Correctly

ground level

high-altitude

low-altitude

mid-altitude
Solution

Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.

57% Answer Correctly

blood type

postive or negative

universal recipient status

universal donor status
Solution

Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.

4

Which of the following substances gives up positively charged hydrogen ions (H+) when dissolved in water?

55% Answer Correctly

base

alkaline

solution

acid
Solution

An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.

5

Generally, an atom has __________ negative electrons orbiting the nucleus as it does positive protons inside.

67% Answer Correctly

more

double the number of

fewer

equal numbers of
Solution

An electron is a subatomic particle that orbits the nucleus of an atom. It carries a negative electric charge. Generally, an atom has the same number of negative electrons orbiting the nucleus as it does positive protons inside.
