Will mark brainliest jimmy and jenny have designed an experiment to test how termites react to the chemicals in ink pens. they use one termite in their experiment. jenny draws four circles, using four different brands of black ink. jimmy places the termite on each circle of ink and they watch the termite's behavior as it is placed on each circle, one try per circle. in all four cases, the termite veers off the ink circle. jimmy and jenny conclude that termites are not attracted to ink at all. what suggestion would you give jimmy and jenny concerning their experimental design? a) run repeated trails with the one termite. b) use more than one termite and run many trials. c) use more than one termite and the same brand of ink pen each time. d) compare the termite's behavior on ink circles to the behavior on pencil circles.

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.
