Describe the mathematical challenges of counting the “ticks” of a molecular clock.

Molecular clock is a process described to be a way of measuring time depending on the random changes or mutations in DNA of an organism. It is somehow mathematically challenging because we will be having a hard time to identify the certain changes and take note of the time elapsed. 

The speed of  sound:   sound travels  at different speeds depending on what it istraveling through. of the three mediums (gas, liquid, and solid)  sound waves travel the slowest through  gases, faster  through  liquids, and fastest  through  solids.

Yes yes yes very good
