In Madagascars cientists have discovered a moth, xanthopan morganil praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin's orchid, Angraecum sesquipedale. The orchid has a nectar-producing tube that Is 27.9 cm long.
How Is the moth's proboscis size an adaptation for Its environment?

• The moth can avold larger animals.
• The moth can pollinate other flowers
• The moth has little competltlon for food.
• The moth has time to feed during the day.

A prey populatlon consists of Individuals with a variety or running speeds.
The adaptation that allows some or these animals to run fast would be an example or natural selection if it helps them...

• survive and undergo mutations In their DNA
• ower the mortality rates of the population
• produce offspring mat run at average speeds
• reproduce and Increase me frequency or their genes In the population
