Question

question 9 (1 point) listen what is a trace element? a) an element that is very common in nature b) an element that is used to identify the location of other elements c) an element that is evenly distributed on the planet d) an element that is required in miniscule amounts for life

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Trace elements are not very common in nature (they are present in small amounts), so A is incorrect.
• Option B: Trace elements are not used to identify the location of other elements; this description does not match the definition of a trace element, so B is incorrect.
• Option C: Trace elements are not evenly distributed on the planet, and their distribution is not the defining characteristic, so C is incorrect.
• Option D: By definition, a trace element is an element that is required by living organisms in very small (minuscule) amounts for normal physiological functions. This matches the correct definition of a trace element.

Answer:

D. An element that is required in miniscule amounts for life
