What will occur when the carrying capacity for humans is met ?
a. the population will increase
b. natural disasters will increase
c. diseases will increase
d. the death rate will decrease

Diseases will increase bacause many people will be compacted next to eachother and that can spread bacteria faster

C. Diseases will increase

Explanation:

Carrying capacity refers to the maximum population size that can be supported by a system. One the population reaches its carrying capacity, several factors become functional reduce its size. If human population meets its carrying capacity, scarcity of resources such as food, shelter and reproduction would increase the intraspecific population. Starvation or malnutrition can give rise to many diseases to reduce the population size.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
