I think it’s a trait is a characteristic
Answer:
b.Their cell walls have very different biochemical properties.
Explanation:
Cellulose is a homopolysaccharide of glucose residues and is the main chemical component of the cell walls of the plant cells. The glucose residues in cellulose are linked together by beta 1-4 glycosidic bonds. Chitin is a linear homopolysaccharide of glucose residues and is the main structural component of the fungal cell wall. On the other hand, peptidoglycan is the major structural component of the bacterial cell walls. Peptidoglycan is a heteropolysaccharide of two different residues. These are N-acetylglucosamine and N-acetylmuramic acid. Therefore, the chemical components and that make the cell walls in plants, fungi and bacteria differ significantly from each other imparting them distinct chemical features.
What’s the rest of the question??
Answer:
Mechanical incompatibility.
Explanation:
Mechanical incompatibility: occurs when species cannot mate because their reproductive structures are incompatible – In animals with internal fertilization, male and female sexual organs may not fit together – For example, snails of species whose shells have left-handed spirals may be unable to copulate successfully.
Mechanical incompatibility of male and female genitalia is common in animals with internal fertilization. However, our knowledge regarding the precise mechanisms is limited.
