B 0.29 I’m sorry if that’s not the answer
Low temperature is the most responsible factor for lack of plants in polar regions.
<u>Explanation:</u>
Due to extreme low temperatures in the polar areas, the soil in this area is completely frozen. In this case, the roots of the plants do not grow very deep. Therefore, there is little or no thick vegetation in this region.
The polar climate is a place where the available temperature is usually lower than cold, icy, snowy and does not get direct sunlight. The Polar Regions, also known as frigid areas. These are planet regions that cover the geographical poles (north - Arctic and south - Antarctic) and are located in the polar Circle.

Answer:

an object that measures the height of objects.
Answer:
The diagram is attached below.
Explanation:
when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.
Both atoms bonded together through ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
