An environmental microbiologist collects a water sample that contains bacteria that have not contacted the outside world for thousands of years. He uses sterile technique while transporting then back to the lab for testing. To his surprise, they are resistant to ampicillin. Based on your knowledge of bacterial evolution, which of the following statements provides the most reasonable explanation for this discovery? a. The bacteria are a result of contamination on the way to the lab.
b. The bacteria do not contain 50S ribosomal subunits.
c. Vancomycin is a naturally occurring mineral occuring in the cave water.
d. The bacteria randomly acquired a mutation in their cell wall building machinery.

The answer is "Option d".

Explanation:

These genetic mutations in heritage in the genome of the bacterium were referred to as biofilm formation. All those other changes are attributable to some genetic changes during replication. The short term of bacteria and vast quantities of the colony can develop rapidly.

The type of environmental choice then transfers into another generation. Some translations benefit human people and enhance their fitness.

The most logical cause for this finding is Option "D", and although types of bacteria have not been in contact with the outside world for hundreds of years, certain random changes resist penicillin.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
