Answer: population increases by 15
Explanation:
The population growth will be calculated by adding the Natural Increase in population plus the Net In-Migration. This will be:
Natural increase = Birth - Death rate
= 35 - 7
= 28
Net-In-Migration = Immigration - Emigration
= 4 - 17
= -13
Therefore, population growth will be:
= 28 - 13
= 15
Therefore, population increases by 15
Answer:
Temperature is the most harsh abiotic factor that limits distribution of the tundra biome.
Explanation:
The tundra biome can be described as a biome that is one of the most abundant biome of the earth but allows little growth of trees due to its very cold temperatures. Often, in a tundra biome, no trees would be seen. The ground soil of this biome remains frozen most of the year and is termed as permafrost. The tundra biome shows very little biodiversity due to the extreme cold conditions. Very few animals and plants are adapted to live in these conditions.
It reduces
Explanation:
The density of the heated mantle rock reduces because its volume has increased.
- Frictional heat, heat from radioactive decay and heat that accretted originally when the earth was forming are responsible for heating the mantle.
- When a substance is heated, it expands and its volume increases.
- Density is a function of mass and volume.
- The higher the volume, the lower the density.
- The higher the mass, the higher the density.
- When the mantle is heated, its volume increases to a new one and its density reduces.
