When comparing archaea with bacteria, both archaea and bacteria are easily cultured and studied in the laboratory. a. the chemical nature of the cell wall of archaea and bacteria is identical and shows their early relationship. b. bacteria are not very diverse and are limited in distribution, while archaea are far more diverse and found everywhere. c. the archaea and bacteria are both derived from early eukarya. d. none of the choices are true.

Option D

Explanation:

None of the characters are true regarding bacteria and archaea. Both of the species have different composition of cell wall. The cell wall of bacteria is made of peptidocglycan and archaea's cell wall lack peptidoglycan.

Bacteria and archaea both are very diverse and are found in variety of environment. They both are found in the extreme environmental conditions.

Archaea and bacteria both are not derived from the eukarya. According to the endosymbiotic relationship the eukaryotes are developed from the prokaryotes.

hence, none of the statements are true.

None of the choices are true.

Explanation:

The three main domains of life are prokarya, eukarya and archaea. The archaea and eukarya are more similar with each other than the prokaryotes.

The archae are found in extreme habitats and both prokarya and eukarya are diverse in nature and almost found everywhere. They have different cell wall composition and bacteria cell wall is made of peptidoglycan. The eukaryotes have been evolved from the prokaryotes and prokaryotes and archae are not derived from eukarya.

Thus, the correct answer is option (D).

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.
