For the first one, electrons travel around the nucleus in fixed energy levels with varying energies.
Second one, protons, neutrons, and electrons have a mass, but electrons have far less mass
Third one, cations and protons
Fourth, not sure.
Answer:
Low rates of evaporation
Polar climate is found in regions around the north and south poles. They include the Arctic and Antarctica regions.
Explanation:
The regions are mainly cold, dry and windy. This is mainly due to their positionon earth relative to sun causing them to receive very little annual sunlight energy compared to other latitudes of the earth. Therefore most of the moisture is locked up in ice hence the dryness of the region. This is not helped by the thin atmosphere in these regions. This means they cannot retain heat because infrared (the electromagnetic waves responsible for heat transfer) boucing up from the earth's surface easily escapes back to space from this region of earth. The heat needed to spur precipitation, therefore, lacks and hence the dryness. Temperatures in these regions range at averages of 10 degrees centigrade on the warmest summer months.

Answer:
The correct answer will be option- D.
Explanation:
The somatic nervous system is divided into two divisions: the afferent neurons (sensory) which bring signals to the CNS and the efferent neurons (motor) which brings the signals to the muscle at the neuromuscular junction.
The motor neurons bring the signals in the form of the action potential which is sent to the muscle through motor wend plate which triggers a response in the muscle cells in response to the stimuli.
Thus, option- D is the correct answer.
Spermatogenesis is the process of formation of haploid sperms for diploid stem cell
Oogenesis is the process of formation of ovum
