ANSWERS:-
11.option = d,
That viruses are not made up of cell.according to cell theory, this means that VIRUSES ARE NOT LIVING.
12.option=C
USING OF HIS EYES randy needs to distinguish two points that are 0.5mm apart. So it is the easiest way to do this.
13.option= C
SACNNING ELECTRON MICROSCOPE is a microscope provides a three dimensional viem of the surface of an object.
14.option=B
Biologist classify cell into two broad categories animals and plants is is FALSE BECAUSE TWO CATEGORIES ARE PROKARYOTES AND EUKARYOTES.
15.option= B
CYTOPLSAM is the name of the semisemi fluid medium inside the cell. Because the actual liquid itself is a fluid matrix called the cytosol. Which is a solution containing ions and smaller molecules such as simple sugar and amino acids.
16.option=B
"A Phospholipid Bilayer. The plasma membrane is composed of two phospholipids. Which consist of fatty acids and alcohol.the phospholipids in the plasma membrane are arranged in TWO LAYERS.
17.option=C
paleontologist have discovered ancient prokaryotic fossils dated at over 3.5 billion years old. These fossils resemble prokaryotes that are capable of living in extreme conditions such as high temperature and salinity. And these are belongs to ARCHAEA.
