Answer:
D
Explanation:
A meteorite is a meteor that impacted the Earth.
(b) electrolytes are what sodium, chloride, and potassium in cells and body fluids are examples of.
When dissolved in water or bodily fluids, a substance called an electrolyte separates into ions (particles having electrical charges). The ions sodium, potassium, calcium, chloride, and phosphate are only a few examples.
The many electrolytes include sodium, calcium, potassium, chloride, phosphate, and magnesium. They come from the meals you consume and the liquids you drink.
Your body's electrolyte levels might get too high or too low. When your body's water balance changes, this may occur. The amount of water you consume and lose should be equal. If something throws off this equilibrium, you can be dehydrated or have too much water on your body (overhydration).

c. condensates.
d. solvents.
Answer:
The correct answer is option d, that is, endocytosis.
Explanation:
A procedure in which a component gains entry within the cell without getting passed through the cell membrane is termed as endocytosis. In this process, the cell captivates the substances from the external of the cell by engulfing and combining them with its plasma membrane.
The process is further differentiated into three distinct kinds. These are phagocytosis, pinocytosis, and receptor-mediated endocytosis.
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.
