- Use process of elimination
- Budget your time!
1. By discharging electric sparks into a laboratory chamber
atmosphere that consisted of water vapor, hydrogen gas,
methane, and ammonia, Stanley Miller obtained data that
showed that a number of organic molecules, including many
amino acids, could be synthesized. Miller was attempting to
model early Earth conditions as understood in the 1950s. The
results of Miller’s experiments best support which of the
following hypotheses?
(A) The molecules essential to life today did not exist at the
time Earth was first formed.
(B) The molecules essential to life today could not have been
carried to the primordial Earth by a comet or meteorite.
(C) The molecules essential to life today could have formed
under early Earth conditions.
(D) The molecules essential to life today were initially selfreplicating proteins that were synthesized approximately four billion
years ago.

GRID IN
- 4 function calculator
- Grid in your answer, as we
have been doing in class
- Will be given a formula sheet.
Four function scientific calculators
with a square root function are
required
In a certain species of flowering plant, the purple
allele P is dominant to the yellow allele p. A
student performed a cross between a purpleflowered plant and a yellow-flowered plant. When
planted, the 146 seeds that were produced from
the cross matured into 87 plants with purple
flowers and 59 plants with yellow flowers.
Calculate the chi-squared value for the null
hypothesis that the purple-flowered parent was
heterozygous for the flower-color gene. Give your
answer to the nearest tenth.
