This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. calculate the estimated time period it takes for 1 base pair to mutate.

17.1/.76 = 90/x   x=4  90/4=22.5m

Explanation: i think

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.

the  different  of  these  two  are  that  they  differently  handle  their  team.
