Materials are stored primarily in vacuoles in single-celled organisms because

A vacuole is known as the storage bag for a cell. Vacuoles are ideal for storing substances because they have a membrane which separates it from other parts of the cell. A vacuole can store nutrients as well as the wastes which need to be excreted. The vacuole helps a single-celled organism to acquire a shape.

In single-celled organisms, vacuoles facilitate the entry and exit of water from the cell and hence help the organism in locomotion.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
