A transparent metric ruler is placed on the stage of a microscope and observed under low power. The diameter of the field of vision was found to be 2 millimeters. This is the number of micrometers in the diameter.
What is 2000 micrometers?

A student formulated a hypothesis that cotton will grow larger bolls (pods) if magnesium is added to the soil. The student has two experimental fields of cotton, one with magnesium and one without. This is the data that should be collected to support this hypothesis.
A) height of the cotton plants in both fields
B) diameter of the cotton bolls in both fields
C) length of the growing season in both fields
D) color of the cotton bolls in both fields

The graph below provides information about the reproductive rates of four species of bacteria, A, B, C, and D, at different temperatures.
This statement is a valid conclusion based on the information in the graph.
a) Changes in temperature cause bacteria to adapt to form new species.
b) Increasing temperatures speed up bacteria. reproduction.
c) Bacteria can survive only at temperatures between C and
C.
d) Individual species reproduce within a specific range of temperatures.
What is 'D'?
('a' is wrong b/c there is nothing about adaptation in the graph.)
('b' is wrong b/c increasing temperature speeds up reproduction for SOME bacteria and kills other bacteria.)
('c' is wrong b/c the graph doesn't show below or above that range.)

A student conducted an original, well-designed experiment, carefully following proper scientific procedure. In order for the conclusions to become generally accepted, this must be done.
What is the experiment must be repeated and replicated?

This sentence represents a hypothesis.
a) Environmental conditions affect the pollination of plants.
b) Boil 100 milliliters of water, let it cool, and then add 10 seeds to the water.
c) Is water depth in a lake related to available light in the water?
d) A lamp, two beakers, and elodea plants are selected for the investigation.

The graph below represents the growth in length and mass of a fetus up to week 32. The length is measured in millimeters (mm) and the mass in grams (g).
This statement best describes human fetal growth between weeks 26 and 32.
a) There is a faster rate of increase in mass than in length.
b) The rate of increase in mass levels off, while the increase in length constantly increases.
c) The fetal mass increases by 750 g and the fetal length increases by about 100 mm.
d) There are slight decreases in both length and mass.
What is 'A'?

The current knowledge concerning cells is the result of the investigations and observations of many scientists. The work of these scientists forms a well-accepted body of knowledge about cells. This body of knowledge is an example of this.
What is a theory? (Specifically Cell Theory)

The diagram below represents the measurement of a biological specimen.
The approximate length of the specimen in millimeters is this.
What is 25 mm?

A student needs 20 milliliters of water for an experiment. This is the amount of water that the must add to the graduated cylinder.
What is 7 ml?

To test the effect of hormones on plant growth, six potted plant seedlings of the same species were measured and then sprayed with auxin (a growth hormone). After four weeks of growth under ideal conditions, the plants were measured again. To set up a proper control for this experiment, the investigator should do this.
What is 'grow six plants under normal conditions and spray them with only water'?

This must be done for the results of an experiment to be considered valid.
The results must be reproducible many times in many different experiments.
