While analyzing a karyotype, geneticists identify a missing chromosome. Which term describes this chromosomal abnormality? aneuploidy
polyploidy
triploidy
tetraploidy

Aneuploidy

Explanation:

Aneuploidy is the presence of abnormal normal of chromosomes in a cell. Example: The chromosomes number 45 or 47 chromosomes which is not common in case of human beings.

The normal number of chromosomes in human beings is 46. This results in different syndromes which can cause deformities in the body of the individual.

It leads to miscarriage in most of the cases the survival is very less.

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.
