Explanation:
The very primitive and early microorganisms on the earth's surface were protobionts. Protobionts are cell-like microscopic structures, and they are made up of organic and inorganic molecules present in a lipid bilayer membrane. The layers of the lipid membranes were folded into bilayers and transformed into a bubble shape when placed in water. These membranes were selectively permeable and also observed shrinkage and swelling in osmotic conditions. Protobionts also possess the characteristics of reproduction.

Option a. prokaryotic cells reproduce asexually using binary fission, while eukaryotic cells use mitosis to divide
Answer:
However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
Explanation:
The phase of mitosis where chromatids being pulled to opposite ends of the cell is called anaphase. Metaphase before includes chromosomes lining up single file at the middle of the cell. The t<span>elophase involves</span><span> nuclear membrane forming around chromatin</span>
