4. Two experiments were mentioned in the talk: one that tested food preference in caterpillars, and another that tested for egg-laying preferences in adult butterflies. What were the results of those two experiments, and what did those results imply​

Respuesta :

Jaap de Roode is a biologist that featured on TEDTalks so the query hyperlinks to him.

What happened to pathogen?

The danger in the use of man-made medicinal drug whilst treating positive pathogens consists of an inclination for the pathogens to grow to be a resistant strain.

  • Just like humans, the monarch butterfly on occasion receives ill way to an uncongenial parasite. Monarchs survives with milkweed; their caterpillars devour milkweed vegetation only (Asclepias spp.), and monarch butterflies want milkweed to put their eggs.
  • But biologist Jaap de Roode observed some thing thrilling approximately the butterflies he changed into studying - inflamed girl butterflies might select to put their eggs on a particular sort of plant that helped their offspring keep away from getting ill. How do they recognize to select this plant. Think of it as "the alternative butterfly effect"- that can train us to discover new drug treatments for the remedy of human disease.

Answer:

1st Experiment:

In the first experiment, they tested what food preference caterpillars had between the toxic milkweed and the non-toxic milkweed. The results of the experiment came out "boring" says De Roode. All of the caterpillars ate 50% of the non-toxic milkweed and ate 50% of the toxic milkweed.

2nd Experiment:

In the second experiment, they tested for egg-laying preferences in adult butterflies. They noticed that the adult butterflies laid 60% of their eggs in toxic milkweed and about 30% (the rest) on the non-toxic milkweed. The butterflies greatly preferred toxic milkweed to non-toxic.

(What the results imply)

These results imply that monarch butterflies self-medicate to help themselves and their babies to fight the diseases and parasites that they often are exposed to.
