2. Scientists have found a gene that makes a protſein called PKG that controls certain behaviors in many
types of ants. The soldier ant will help collect food
when it has a low level of PKG. When it has a high
level of PKG, the soldier ant will protect and defend
its colony. Soldier ants that are given PKG are more
likely to ignore food sources and attack intruders.
Which conclusion can best be made from this
information?
A) PKG protein is synthesized only by the soldier
ants.
B) Genes control which type of amino acids a cell
can make
C) Eating too much protein makes some organisms
very aggressive
D) The behavior of soldier ants is controlled in part
by the PKG protein.
