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 and Explanation:
Darwin observed that members of a species in a population especially those that reproduce sexually show certain variations. Some of these variations are caused by genes hence can be inherited. Some of the inherited characteristics make the individuals possessing them better suited to the prevailing environmental conditions. This enables such individuals to stand a better chance to survive in the struggle for existence. Accumulation of this gradual changes in a populations due to natural selection leads to formation of new species that are better suited to the environment.
