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:
C: Lowering activation energy
Explanation:
A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction.
I'll choose Commensalism.
Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. It works when one species typically uses the other for a purpose other than food. For example, mites attach themselves to larger flying insects to get a “free ride.” Hermit crabs use the shells of dead snails for homes.

presence of cyclins and cyclin-dependent kinases are the main regulators of
cell cycle. Therefore, the excess of cyclin, due to a mutation in the genes for these proteins, that pushes the cycle forward cause the <span>proliferation of cells. Also, a mutation in the tumor suppressor
gene would cause a repression of tumor suppressor proteins which are significant
in inhibiting progression of the cell cycle.</span></span>
