Answer:
c. Fungi
d. Yeast
Explanation:
Both fungi and yeast will be effectively removed by a 0.22 micron pore size filter.
<em>The size of microscopic fungi ranges from 2 to 10 microns while the size of yeast ranges from 3 to 4 microns in diameter. Hence, both organisms will be effectively filtered off by a 0.22 micron filter paper.</em>
The size of bacteria ranges from 0.2 to 2 microns while that of virus is in nanometer. Hence both cannot be effectively removed by a 0.22 micron pore size filter paper.
The correct options are c and d.

Answer:
<u><em>DNA is made of repeating units called nucleotides.</em></u>
Explanation:
DNA can be described as a double helix molecule made up of long polymer chains of nucleotides. The nucleotides which are present in a DNA are:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T)
The hydrogen bonds which occur in the pairing of nucleotides makes the double helix structure of DNA.
Adenine forms hydrogen bonds with Thymine.
Guanine forms hydrogen bonds with Cytosine.
The backbone of the DNA is made up of sugars and phosphates
