Answer:
True
Explanation:
I'd say its true due to the fact Lichens are very sensitive to pollutants in general.
Answer:
The question is incomplete.
However, I notice that your question is mainly dealing with
"Nucleotides with a single ring structure"
I tackled that part, also providing explanation to the point you focused on.
Explanation:
Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.
Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.
The correct answer is Alcoholic dementia.
Alcohol-related dementia (ARD) is a type of dementia brought on by prolonged, excessive alcohol use, which damages the brain and impairs cognitive function.
Wet brain, sometimes referred to as Wernicke-Korsakoff syndrome, is another type of ARD that is characterized by short-term memory loss and thiamine (vitamin B1) deficiency.
Patients with ARD frequently exhibit both type's symptoms, such as memory loss, apathy, and impaired planning. ARD may coexist with different types of dementia (mixed dementia). Despite being widely accepted, the diagnosis of ARD is only occasionally used because there aren't any clear diagnostic criteria.
Hence, the patients with generalized loss of brain tissue due to direct consumption of alcohol suffers from alcoholic dementia which causes memory loss and many other problems.
