In biology or human geography,population growth is the increase in the number of individuals in apopulation. Global human populationgrowth amounts to around 83 million annually, or 1.1% per year. The globalpopulation has grown from 1 billion in 1800 to 7.616 billion in 2018.
Answer:
A, natural selection
Explanation:
Evolution could be correct also, but I don't think it is, since the question asks about individuals that have a higher chance of reproduction
Answer:
c. They may evolve into two separate species as a result of disruptive selection
Explanation:
Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.
With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.
My answer would be "Earthquakes happen along cracks in the earth's surface, called fault lines, and can be felt over large areas"
Answer:
Negative growth rate is when a population's average number of deaths is greater than its average number of births. Zero growth rate is when the average number of deaths equals the average number of births.
