Let's calculate the difference in nucleotides. The number of difference multiplied by rate of mutations will help to determine how long ago these two species shared a common ancestor.
Species A: GTACCTAAGTTCACCGAATT
Species B: GAACCTAAGGGCACCGAACT
These species differ in 4 nucleotides.
This number should be multiplied <span>by </span>the rate of mutations
Answer:

Sensation
detection of physical energy by sense organs, which then send info to the brain
- Detection of stimuli by sense organs
- how info gets to our brain = detecting stimuli
- allows us to pick up the signals in our environment
- ex. vision- going through eye to visual cortex and smell - going through nose.
