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.

Answer:
None of the Above.
Explanation:
The correct answer is fitness. The Theory of Evolution defines fitness as a result of the adaptations an organism has which increase its chance of survival.
Answer:
Compound
Explanation:
It is a chemical compound because it is something composed of one or two elements.
The right options are;
A.The population of pink katydids will decrease.
B.The population of green katydids will decrease.
What will eventually happen to the population of the katydids is that the population of both the pink and green katydids will decrease. The predators which are the birds that feeds on the katydids (prey) will negatively influence the size of the prey populations by reducing them.
