Lyndon is investigating whether putting plastic on her windows will help seal out cold winter drafts. She covers a window on the south side of her house with plastic and measures the inside temperature near the window. She also measures the inside temperature near a window without plastic on the north side of her house. The windows are the same size and design. Why is this not an ideal controlled investigation?
A.
The windows should be different sizes to introduce variation.
B.
The drafts at each window may be different because the windows aren’t near each other.
C.
Temperature isn’t a good indicator of cold winter drafts.
D.
Outside temperature is a better indicator of cold winter drafts than inside temperature.
E.
The type of plastic used in the investigation isn’t mentioned.

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
