Aresearcher is involved in the investigation of an individual's genetic abnormally. which situation could the researcher most likely rule out as the genetic cause of a mutation?

Answer;

Formation of an adenine-uracil base pair

Explanation;

-Mutations are sudden spontaneous changes that occur randomly in the genome or genetic make up of an organism. These changes occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.

-Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

-Mutations happen for several reasons which includes; failure of DNA to copy accurately, external influences or factors such as specific chemicals and radiations.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
