Scale is a proportion between two sets of measurements. For example, 1 centimeter on a map might represent 1 kilometer in actual distance. The diagram above on this page is a model of chromosomes,
DNA, and genes. Are all components of the model shown at the same scale? Explain your answer.

Each trait of a plant is determined a. an allele b. one gene c. a pair of genes d. one dominant gene

The theories on the expansion of galaxies maybe re-examined to strengthen science should not be tested to strengthen science will weaken scientific knowledge if they change will become laws if they don't change

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
