It is just s. It is for second.
Answer: This is an extremely drug resistant bacteria that must have inherited genes against this drug resistant from a parent bacteria that was exposed to the drug or substance. The parent bacteria went through a mutation to survive this environmental pressure and transferred that gene or mutation to its offspring.
Through natural selection and horizontal gene transfer this bacteria is able to survive in the presence of a molecule that is supposed to kill it and has developed extreme resistance against.
Speciation is the creation of a new species distinct from the original due to evolution.
I will walk through how this will work for you.
1. Animals of the same species living on either side of a stream can move from one side to another.
2. The stream changes into a river
3. Animals are now separated and must live apart
4. Environments on either side of the river change over time.
5. Animals due to natural selection, undergo change
6. After a thousands of years, two different of species form.
Hope this helps.
Oil-immersion objectives are limited to use with coverslip-prepared samples, since they don't have enough working distance to focus through the 1 mm or thicker plastic wall of a typical cell culture vessel.
