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.

Answer:

d. xylem and phloem

Explanation: plants possess vascular bundles.these are bundles which includes xylem and phloem tissues and transport useful substances to various plant cells.

New Xylem and phloem are formed from the vascular cambium which divides into new cells .

Xylem and phloem are thin and slender with pipe-like structure.

The xylem transports water and dissolved nutrients to the cells where they are needed.

The phloem transports the product of photosynthesis (sugar) to parts what they are used up or stored .

Xylem cells are dead and consists in vessels,trachieds and xylem parenchyma.

Phloem cells are dead and consists in sieves cell, companion cells, phloem parenchyma and phloem fibres.
