Answer:
1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.
2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.
3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).
4.Establish a theory based on repeated verification of the results.

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:
Although most adults won't grow taller after age 18 to 20, there are exceptions to this rule. First, the closure of the growth plates may be delayed in some individuals. If the growth plates remain open past age 18 to 20, which is uncommon, height could continue to increase.
