Answer:
<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
Answer:
Answer of the question is explaine dbelow.
Explanation:
Rho GTPases interact with a variety of effectors to control actin cytoskeleton
reorganization, cell shape, and cell polarity. RhoA regulates cell shape and adhesion by
the assembly of contractile actin microfilaments into stress fibres. Rho GTPases also
regulate proliferation and cell-cycle progression, especially GuS transition.
All the cells are about to enter mitosis means they cross GuS transition, a drug that is a
potent inhibitor of RhoA activity has no affect on the cell because these cells already in
G2 phase. So, all the cells appear to be in telophase.
So, the correct choice is A. all the cells appear to be in telophase.
Answer:
Petri dishes are widely used in biology to cultivate microorganisms such as bacteria, yeasts, and molds.
Explanation:
It is most suited for organisms that thrive on a solid or semisolid surface.
