Suppose a certain poison kills human cells by blocking pores in the nuclear membrane. explain why it would or would not kill bacteria.

Bacteria is a member of a huge group of unicellular microbes that exhibit cell walls, however, are devoid of cell organelles and an organized nucleus, it even comprises some of the species that can result in disease. Bacteria are generally differentiated into three classes, categorized by shape, that is, cylindrical, spherical, and spiral.  

A certain poison kills cells of humans by obstructing the pores in the nuclear membrane. However, the same poison would not kill the bacteria as bacteria are devoid of a nuclear membrane as it is a unicellular species, and is considered as a prokaryote.  

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.
