Of the following choices, what is the approximate LD50 of the least toxic substance? 20 mg/kg, 70 mg/kg, or 130 mg/kg
pychu [463]

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.

Do autotrophs need to perform cellular respiration?
nydimaria [60]
Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
