Answer:
True.
Explanation:
The unequal distribution of ions inside and outside of the cell makes the membrane potential of the cell. The potential is important for the conduction of the impulse and generation of the action potential.
The resting membrane potential of the nerve impulse is maintained by the presence of large potassium ions inside the cell. The resting membrane potential is -70mV. The depolarization of the membrane occurs due to influx of the sodium ions.
Thus, the answer is true.
Answer:
b
Explanation:
because an object is in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
Nuclear fission occurs when an atom splits into two or more smaller atoms, most often the as the result of neutron bombardment.
The build-up of fats, cholesterol, and other substances in and on the artery walls. A build up of cholesterol plaque in the walls of arteries causing obstruction of blood flow. Plaques may rupture causing acute occlusion of the artery by clot.
