Answer:
Bacteria contain peptidoglycan in the cell wall; archaea do not.
Explanation:
The cell membrane in bacteria is a lipid bilayer; in archaea, it can be a lipid bilayer or a monolayer. Bacteria contain fatty acids on the cell membrane, whereas archaea contain phytanyl.
Answer:
Genetic drift does not require the presence of variation.
Explanation:
Genetic drift is the random changes to the frequency of an allele in a given population.
Natural selection is the process whereby organisms that are well adapted to the conditions in an environment can survive and produce more offspring.
- Genetic drift does not require variation to occur.
- It usually occurs even when there is less to no variation.
- Natural selection occurs when variation is very large.
- A highly varied gene pool causes natural selection.
Answer:
Following are the similarities between vacuoles and lysosomes.
1) Both vacuoles and lysosomes helps in the removal of water materials from the cell.
2) Both vacuoles and lysosomes are the organelles of the cell which are present in compartments.
3) Both vacuoles and lysosomes helps in the digestion of food materials inside the cell.
4) Both vacuoles and lysosomes holds materials inside their structure which are necessary for the cell.
