He used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
Answer:
Cyclin dependent kinase 1 or CDK 1 is a catalytic protein whose action is regulated by cyclin B.
Explanation:
CyclinB-CDK 1 complex is also termed as maturation promoting factor that helps in the entry of the cell into the M phase.The concentration of Cyclin B -CDK1 rises by various process such as dephosphorylation and falls by the degradation of cyclin B.
The cyclinB-CDK 1 is inactivated by phosphorylation of at tyr 15 residue.cyclinB-CDK1 interacts with various proteins such as survivin,which is essential for spindle formation that in turn regulate the cell viability.
After depolarization phase of an action potential, the resting membrane potential is restored by A . The opening of voltage-gated potassium channels and the inactivation of sodium channels
After the depolarization of resting membrane potential is completed, and the membrane becomes depolarized, the membrane again comes back to its initial resting membrane potential which is done as after a brief period of time, the sodium channels self-inactivate (close and stop responding to voltage), halting the sodium influx.
The opening of a group of voltage-gated potassium channels lets potassium stream out of the cell via its electrochemical gradient. These occurrences swiftly reduce the membrane potential, returning it to its regular resting state.

Answer:
fission
Explanation
Where does asexual reproduction take place? When single-celled organisms (like bacteria and protozoa) just split (or break) into two identical halves during cell division, leading to the creation of new organisms is called fission.
Hope fully this is correct.
