The label of a vitamin supplement must state the existence of a tolerated upper intake level (UL) if one has been developed. The assertion is true.
Is it mandatory to give a tolerable upper intake level(UL) of vitamins?
- Tolerable upper intake level(UL) is the highest amount of a nutrient that is chronically consumed each day (from all sources) and is deemed unlikely to have a negative impact on human health.
- In this sense, "tolerable intake" refers to what is physiologically safe. It is a scientific evaluation based on risk assessment, i.e., the likelihood that an unfavorable impact would manifest at a certain amount of exposure.
- For different demographic life stage groupings, ULs may be generated. It is not advisable to consume more than the UL. It is a projection of the maximal consumption amount with a negligible chance of adverse health consequences.
- A risk assessment is necessary to ascertain the percentage of the population (if any) whose consumption exceeds the UL as well as the extent and frequency of the high consumption in order to evaluate if an affected community is in danger.
Therefore it is concluded that the questioned statement is true.

During contraction, the filaments slide past he thick filaments, shortening the sarcomere. The thick and thin filaments do the actual work of a muscle, and the way they do this is pretty cool. Thick filaments are made of a protein called myosin. At the molecular level, a thick filament is a shaft of myosin molecules arranged in a cylinder. Thin filaments are made of another protein called actin. The thin filaments look like two strands of pearls twisted around each other.

Answer:
Independent variable: The diameter of the wooden pins.
Dependent variable: The depth of the pins in the sand.
Control variable: height of 15 cm at which the pins will be thrown, boxes containing 30 kg of sand and weights of 80 grams.
Explanation:
An independent variable is one that does not need the influence of another variable to happen and that, its variation, influences that a measurable result occurs. In this case, as we know that the depth of the wooden pins is measured according to the influence of the diameter of these pins, we can say that the diameter of the wooden pins is the independent variable.
The dependent variable, on the other hand, is one that shows a measurable result through the influence of the independent variable. In this case, we can say that the depth of the wooden pins in the sand is the independent variable.
The control variable, in turn, is the factor that establishes an egalitarian environment in which the research will be established. In this case, the control variable is the height of 15 cm at which the pins will be thrown, the boxes containing 30kg of sand and the weights of 80 grams.
