Bones are not a suitable sample for drug or poison testing.
a. true
b. false

The answer is true. It is because bones does not have the ability to absorb the substances such as drug or poison for the drug or poison that a person has ingested will be ingested orally and if injected in the skin, but the bones won’t be affected as they are responsible in providing support in the body for us to move with the help of the muscles and they are are a calcified material.

True.

Explanation: Bones are not suitable sample for the drugs or poison testing because bones does not absorbs poison or substances like drugs.

These substances are absorbed by the blood and not by bones so it detectable amount are not found in the bones.

Hence, bones cannot be used as a sample for the detection of substances like drugs and poison.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
