Question: Answer the following question given this paragraph: We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed. Q: As per the kinetic-molecular theory, in what direction do the molecules and ions of liquids move? Choices: - alter directions - opposite direction - same direction - random directions A:
Answer: random directions

Question: Answer the following question given this paragraph: Seedless vascular plants evolved to have vascular tissue after the nonvascular plants but do not have seeds. Examples include the ferns, whisk ferns, club mosses, and horsetails. Vascular tissue allowed these plants to grow taller. Q: Vascular tissue allowed these plants to do what? Choices: - grow smaller - have more flowers - live shorter - grow taller A:
Answer: grow taller

Question: Answer the following question given this paragraph: Following the discovery of the electron, J. J. Thomson developed what became known as the " plum pudding " model in 1904. Plum pudding is an English dessert similar to a blueberry muffin. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge like blueberries stuck into a muffin. The positive matter was thought to be jelly- like or a thick soup. The electrons were somewhat mobile. As they got closer to the outer portion of the atom, the positive charge in the region was greater than the neighboring negative charges and the electron would be pulled back more toward the center region of the atom. Q: Thomson's plum pudding model shows the structure of what? Choices: - nucleus - cell - DNA - atom A:
Answer:
atom
