Answer: Possible life in non earthlike environments.
Explanation: As per the information provided in the question, the microbe located in California's Lake Mono has a variation in the shape of its DNA as they use arsenic ( if phosphorous was once no longer available) to comprise in the nucleotides of their DNA.
This shows the possibility of life structure in the non-earth-like environment because existence types that originated on earth like environment possess carbon, nitrogen, oxygen, and phosphorous ( that is composed of four fundamental elements).
But existence can additionally be shaped in an environment that lacks phosphorous ( for instance, DNA shaped in microbes utilized arsenic in absence of phosphorous, indicating version in their structure).
The answer is C, hope I helped (:
Destruction of myelin will affect the nerve and there will be the less conduction of electrical impulses from the brain to other parts of the body and the nerve signal sent to the brain are delayed. These damaged nerve areas form sclerosis which disrupts the signalling capacity of the nerve. This may occur due to genetic defects, infectious agents, auto immune reactions and trauma.
