Answer:
In gram staining, 95% ethanol is used to destain the gram-negative bacteria but gram-positive bacteria do not get destain because peptidoglycan layer in gram-positive cell wall does not allow crystal violet- iodine complex to come out of the cell wall.
Gram-negative bacteria do not have peptidoglycan cell wall and so crystal violet comes out of the cell wall by using 95% ethanol because ethanol dissolves the lipopolysaccharide membrane of gram-negative bacteria and allow the dye to leak out.
Therefore if I forgot to apply 95% ethanol than crystal violet dye will not come out of the lipopolysaccharide cell wall of gram-negative bacteria and it will appear violet under the microscope.
Answer:
The greatest degree of genetic variation would be found in an offspring resulting from sexual reproduction.
Explanation:
Explanation: Asexual reproduction produces very less variations. Asexual reproduction requires only one parent and thus the offspring would be very similar to the parent.
Lessen impacts of flooding by absorbing water and reducing the speed at which flood waters flow. Upstream wetlands can serve to store flood waters temporarily and <span>release them slowly downstream.</span>
