Answer:
The adaptation in owl butterfly helps it to camouflage and also protects it from predators. Adaptations allow organisms to be better suited to their environment. So the answer is both 'A' and 'B' .
Explanation:
Owl butterfly use the concept of mimicry. It is a form of <em>adaptation</em> in which they fool the predator in thinking that they are owls and not butterflies. These butterflies have eyespots under their wings. By flashing them they look like the <em>eyes </em>of an owl.
Since owls feed on small animals, and small animals feed on butterflies, the owl butterflies protect themselves from predators. The small animals thinking that the butterfly is an owl, run away instead of coming closer. This way these small insects camouflage and protect themselves.
Answer:
False
Explanation:
Lipopolysaccharides are substances that have both lipid and polysaccharide. LPS layer is the characteristic feature of gram-negative bacteria. The LPS layer is present in the outer membrane of the cell envelope of gram-negative bacteria. It is not found in Gram-positive bacteria.
Broad-spectrum drugs are the chemotherapeutic agents that are effective against several kinds of pathogens while the narrow spectrum drugs target only a limited type of microbes. Therefore, an antibiotic that attacks the LPS layer would be effective against Gram-negative bacteria only which in turn makes it a narrow-spectrum drug.
