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.
Mulch<span>, a type of protective covering which is in direct contact with the ground, provides more protection than canopy cover. It can vary from straw, to compost, to wood chips, or saw dust. Spread evenly onto the ground, mulch helps to reduce water evaporation, control weeds, and enrich the soil. It is also significant in protecting soil where vegetation has not had ample time to establish itself. By absorbing the destructive forces of raindrops and wind, mulch reduces erosion until the the seedlings mature enough to provide their own protective cover. thats all I know</span>

Hey i think there is an error in ur question, u may recheck the so called word "metopus"
But here is the definition of Endosymbionts are organisms that form a symbiotic relationship with another cell or organism
The answer is; DNA
The central dogma is DNA- RNA- Protein
Gene therapy involves the replacement of bad genes in the DNA of a human subject with a better gene. A recessive/mutated allele is removed and a healthy one is inserted. This way, the proper proteins can be produced solving the disease trait. Ultimately, it will not require drugs to treat the disease.
