The surface area of a sphere can be approximated as follows:
surface area = 4112;
where ris the radius of the sphere;
it is a constant that is roughly equal to 3.
using the simple approximation above, calculate the surface area of a sphere
with a radius of 2 meters.
o a. 24 m2
o b. 16 m2
o c. 48 m2
o d. 9 m2

What is the term for the two sets of chromatids formed in the parent cell a. haploid b. diploid c. gamete d. tetrad

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.

Error analysis: what might be the reason that some of your percentages didn't exactly match your predicted results? gametes aren't responsible for inheritance. mice don't have large litters, so the sample size was not large enough. the wrong type of mice were used.
