3 multiple choice 1 point which of the following terms represents the smallest part of an element that still has the properties of that element? atom cell 4 multiple choice 1 point select the correct hypothesis for the following relationship between the following independent variable (iv), and dependent variable (dv): iv - amount of caffeine dv - breathing rate of goldfish if the goldfish is given tylenol then the breathing rate of the goldfish will increase. if the goldfish is given caffeine then the goldfish will swim faster. if the goldfish receives caffeine then the breathing rate of the goldfish will increase. 5 hot spot 1 point on the item that would not be used for measurement.

Explanation:

For question 3, an atom is the smallest part of an element that retains its properties. A cell is the basic unit of life and not related to elements. For question 4, a hypothesis should relate the independent variable (amount of caffeine) to the dependent variable (breathing rate of goldfish). The first option has the wrong independent - variable (Tylenol), and the second option has the wrong dependent - variable (swimming speed instead of breathing rate).

Answer:

1. A. Atom
2. C. If the goldfish receives caffeine then the breathing rate of the goldfish will increase.
