Answer;

Electron microscope

Explanation;

Electron microscopy (EM) has long been used in the discovery and description of viruses. Viruses have a size of roughly 1/100 of bacteria (or smaller), so they are too small to be seen in light microscopy.

Viruses are considerably smaller, as they are merely nucleic acid surrounded by a protein shell as opposed to an entire living cell. Viruses typically range from 20-400 nm, which means an electron microscope is needed to see them.

Answer:

d. Monosomy X is the only viable monosomy known to occur in humans.

Explanation:

Human have 22 pair of homologous chromosomoses and an extra pair of sex chromosomes. While in males  the sex  chromosomes  are X and  Y , females have two chromosomes X . Anyway, in normal conditions the total number of chromosomomes that humans have in their cells is 46 (23 pair of chromosomes).  

Aneuploidy is a biological condition where an individual have an abnormal number of chromosomes in their cells.  In humans for examples, this would be a human having more or less than 46 chromosomes.

The Turner syndrome also called  monosomy X is an aneuploidy  where  one of the X chromosomes is missing in a female.  Although under constant supervision, people with Turner syndrome have viable healthy lives. However this is the only monosomy that occur in humans that is compatible with life.
