The answer to your question is option b
This is because if the trees are black, and covered with soot due to the pollution, caused by industrialisation, the white moths will be easily seen and constantly hunted by the predator, compared with the black moth population as they camouflage easily. Ultimately, the white moths would be hunted to such an extent that their population would dramatically decrease
A. is your correct answer.
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Answer:
C) The rate applies to more individuals each year.
Explanation:
Suppose the initial population was 200 people and birth rate was 10% of that. So thats 0.10 * 200= 20 babies that year.
Next year the population is 200+ 20 = 220 people. Now if the birth rate is still 10% then you will have 0.10 * 220 = 22 babies that year.
Did you see that? The number of babies increased by 22-20= 2 extra babies each year.
Therefore, since rate applies to more individuals each year, you'll get increase in population
