The following table represents the number
of bacteria, algae, viruses, and fungi in a
pond at different temperatures. All values
represent the number of millions of
bacteria, algae, fungi, and viruses in a
single liter of water.
1. According to the information
provided in the table, the number of
which of the following substances is
constant after a pond reaches a
temperature of about 20 degrees?
A. Bacteria
B. Fungi C. Algae
D. Virus
2. If the number of bacteria continued
to increase at the same rate as the
pond continued to warm, what would
the measurement be at 30 degrees?
A. 400 B. 640 C. 860 D. 1270
3. Based on the information
presented, the number of which of the
following substances is not
determined by the pond's
temperature?
A. Bacteria B. Fungi C. Algae D.
Viruses

SNORK ACTIVITY
You will make your own SNORK based on the genetic code
given
1. Transcribe the sequence into RNA
2. Translate the sequence into an amino-acid chain
3. Find what A.A. sequence codes for what trait
