Answer: The ultratrace mineral among the options provided is boron. Ultratrace minerals are important for the body's overall functioning, despite being required in very small quantities.
Step-by-step explanation:
Ultratrace minerals are essential minerals that are required by the body in very small amounts. They play important roles in various biological processes, despite their low concentrations.
Let's take a closer look at the options:
1) Boron: Boron is considered an ultratrace mineral. It is involved in the metabolism of calcium, magnesium, and phosphorus, and plays a role in bone health and brain function. It is found in small amounts in certain fruits, vegetables, and nuts.
2) Arsenic: Arsenic is not classified as an ultratrace mineral. While it is a naturally occurring element, it is considered toxic to the body and can have harmful effects even at low levels of exposure.
3) Vanadium: Vanadium is not classified as an ultratrace mineral. It is a trace mineral that is required by the body in slightly larger amounts compared to ultratrace minerals. Vanadium plays a role in insulin regulation and bone health.
4) Molybdenum: Molybdenum is not classified as an ultratrace mineral. It is a trace mineral that is required in small amounts by the body. Molybdenum is involved in various enzymatic reactions and helps in the metabolism of certain amino acids.
