Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.
Answer: Option B & C
<u>Explanation:</u>
Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.
On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.

Answer : Yellow
Explanation : Because purebred plants have lighter colored dominence .
Answer: Peroxisome
Explanation:
A peroxisome is a membrane-bound organelle usually found in the cytoplasm of almost all eukaryotic cells. It is an oxidative organelle.
Eukaryotes are comprised of one or more cells that contain peroxisomes. The organelles were first discovered by the Belgian scientist Christian de Duve, who was same person that discovered lysosomes.
Peroxisomes contain a variety of enzymes, which primarily function together to get rid of toxic substances in the cell, and in particular, hydrogen peroxide which a common byproduct of cellular metabolism. These organelles contain enzymes that convert the hydrogen peroxide to water, making it remain safe in order to be released back into the cell. Some types of peroxisomes, such as those in liver cells, detoxify alcohol and several other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (known as oxidation). Other perixosomes are more important for their ability to initiate the production of phospholipids, which are typically used in the formation of membranes.
