Answer:
oh thanks have a great day
The approximate LD50 of the least toxic substance will be 130 mg/Kg.
- The dose necessary to cause the death of 50% of a population under test after a predetermined test period is known as the LD50 value for a drug.
- Commonly used as a broad indicator of a substance's acute toxicity are LD50 values.
- Greater toxicity is indicated by a lower LD50. A low LD50 of 500 mg/kg or less implies severe toxicity.
- Moderate toxicity is indicated by an LD50 of 500 to 1,000 mg/kg. A modest toxicity level of 1,000 to 2,000 mg/kg is indicated.
- The species is especially vulnerable to the poison if the LD50 is low. The lethal dose (LD50) of a specific poison might change significantly between several animal species.
- Thus out of all the options, LD50 130 mg/kg will have the lowest toxicity and 20 mg/kg will be the highest.

the island is a small specie of lizards so if the mainland specie was a large population it would have been the one to be affected by an increase instead of a decrease. The genetic drift was caused by not having enough of the same kind to keep the heredity going, most likely the largest population is the one that had enough of the same heredity to keep the population of lizards going. In a way the hurricane with the force on both species caused a genetic drift but increased a larger population for a year later.
