Answer:
A) Any butterfly allele that allowed milkweed toxin storage would be likely to persist because butterflies that had it were more likely to survive.
Explanation:
Butterflies are natural preys to birds. Over time, some butterflies evolved adaptive strategy such as developing an allele which enables storage of toxin from milkweed as a form of defense mechanism. This stored toxins repel birds from eating the butterflies having this allele giving rise to the survival of these butterflies overtime. Butterflies that had it are likely to be highly favored for survival against predatory birds, while those butterflies without this allele are likely to be heavily preyed upon by birds.
You can reduce the risks of radiation exposure by:
1. Eating foods that contain chlorophyll. Foods that contain this substance detoxify the blood, helping to remove all kinds of nasty toxins including radiation.
2. Ingest sea vegetables. Kelp, dulse, and agar contain natural iodine, which protects against radioactive iodine found in foods like dairy products.
3. Supplement with bee pollen. It can protect your body against x-ray induced radiation sickness.
4. Limit daily exposure to nonionizing radiation.
