What the scientist already know? and what the scientist learn?

Scientist have never observed any direct contact between adult, large, blues, and Myrmica ants. The pregnant butterflies don’t spot the nest from above, since the flyers lay their eggs during a time of the day, when the answer underground. Plus, the ants really climb the stems of the oregano plants or leave a chemical trail that lasts long enough to be sniffed by the butterflies. However, went under rested by pest, such as when ants destroy their roots, plants are known to produce chemicals toward of invaders. So for the study, Barbero and her colleagues grew oregano in enclosed terrarium with Myrmica ants, and then collected the chemical since admitted by the plant. The researchers found that the plants made twice as much of a chemical agent carvacrol versus normal plants grown Myrmica ants.

The butterflies do not follow a chemical trail left by the ants.

Many plants produce chemicals toward of invaders.

Oregano plants produced twice as much carvacrol as plants without Myrmica ants.

The butterflies do not spot the ants from above.

From this passage, scientists already know that:

- They have never observed direct contact between adult, large, blues, and Myrmica ants.
- The pregnant butterflies do not spot the nest from above.
- The ants climb oregano plant stems or leave a chemical trail for the butterflies to follow.
- Plants produce chemicals to defend against invaders.
- Oregano plants produce carvacrol as a chemical agent.

From the study conducted by Barbero and her colleagues, scientists learned that:

- Oregano plants produce twice as much carvacrol when grown with Myrmica ants compared to normal plants without ants.
