Plants are in the ground with soil
Answer:
Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.
Explanation:
Answer:
There are a number of mechanisms through which a bacterial cell might become resistant to a specific antibody.
- Some bacteria might posses a cell membrane which wouldn't allow the transfer of antibiotics into the cell of the bacteria. Some bacterial cells might not have the target sites on which the antibiotics attack. A bacterial cell that would be non-resistant wouldn't block the entry of the drug or it might not lack the site where the drug has to function.
- Some resistant bacteria might produce enzymes that would inactivate the activity of the antibiotics. This enzyme machinery would lack in a non-resistant strain. The resistant bacteria might have undergone mutations over a period of time to evolve a machinery for antibiotic resistance.
