Answer;
-Hot desert biome
Explanation;
Hot Desert is characterized by very little rainfall or a lot of rain in a very short period. The soils are often salty because minerals do not get washed away. Thus, the climate is characterized by a very little precipitation.
-Plant adaptations: There are few plant species. these plants are adapted to resist drought and store water. For example; Spiny cacti that have thick, fleshy stems that conserve water are common. Their roots extend metres away from the plant to absorb water. Other plants have small, thick, waxy leaves that also store water. Many plants have spines or produce chemicals that protect them from being eaten.
Answer:
Option-C
Explanation:
Action potential refers to the generation of electrical activity due to the influx and efflux of ions in the cell.
The cell which transmits the action potential is known as the neuron and the neuron maintains the membrane potential at -70 mv. The influx of sodium ions causes depolarization when it crosses the threshold value.
The generated action potential now travels in the neuron through its long tubular structure called an axon. The axon transmits the signal from the cell body towards the axon terminal and thus is known as the down the axon.
Thus, Option-C is the correct answer.
I believe it is the Nitrogen cycle although all of the cycles use bacteria. Only nitrogen requires nitrogen fixing bacteria to keep the cycle going.
