Answer:
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Explanation:
The convection is defined as the heat transferred in a liquid or a gas as a result of the actual motion of heated particles within it . If this movement is due to the effect of gravitation, due to differences in density, it is called natural convection.
Explanation:
Uses/Advantages of Renewable Energy
It can be used to generate electricity e.g. hydro energy
It is used for cooking at homes e.g. wood/biofuel.
It enables the growth of our crops e.g. solar energy.
It facilitate movement of people and goods from one place to another e.g. fuel, diesel, natural gas.
Renewable energy lasts a life time
Renewable energy is clean and does not cause pollution
Renewable energy is cheap once it is fully installed
Misuses/Disadvantages of Renewable Energy
It can be used to produce nuclear weapons e.g. atomic bomb
It can cause flooding through overflowing of dams
