I think is # 1 looking at the surface features of a virus. Isbecause #2 can see better than the naked eye, #3 because TEM microscope would kill them and #4 because is too small for the microscope.
<u><em>Electron microscopes are types of microscopes that uses a beam of electrons instead of light to magnify objects up to 500,000 times the actual size. These microscopes have a higher resolving power than the light microscopes since they use electrons.</em></u>
<em><u>There are two types of electron microscopes ; that is Scanning Electron Microscope and Transmission Electron Microscope. </u></em>
<em><u>Transmission electron microscope are used for studying internal structures of cells. In these microscopes electromagnets are used to magnify the image by passing a beam of electrons through a thin specimen.</u></em>
An organism has 28 pairs of chromosomes in its diploid somatic cells. How many chromosomes are in its gametes? diploid = 2n, haploid = n 2n = 28 pairs = 28×2 = 56, n = 28 gametes are haploid = n = 28 total chromosomes
