Students observed bubbles of gas rising from a
photosynthesizing underwater plant. They made
several observations using a light at different
distances from the plant. They took turns
recording their observations in the table.
Which statement MOST likely explains why the
fourth observations does not seem to agree with
the other observations?
The heat from the light caused bubble formation
to slow down.
An error was made by the student who observed
and recorded this rate of bubble formation.
The rate that bubbles formed was not depended
on distance from the light source.
The student used a different meter stick to
measure the distance between the plant and the
light.

How is DNA able to control the synthesis of a
protein in an eukaryotic cell?
DNA condenses into single strands, which are
able to leave the nucleus to synthesize proteins.
The information in DNA is transcribed into
RNA, which can leave the nucleus to synthesize
proteins.
Amino acids enter the nucleus and attach to
DNA, which forms them into proteins.
Ribosomes enter the nucleus, where they can
make proteins while attached to the DNA.
