A hydrometer is an instrument that measures the specific gravity (relative density) of liquids. The ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float
<h2>Answer is option "C"</h2>
Explanation:
- All in all, this procedure includes a "parent" cell parting into at least two "little girl" cells. Right now, parent cell can give its hereditary material from age to age.
- Meiosis, then again, is a particular type of cell division that happens in living beings that imitate explicitly. As referenced above, it produces regenerative cells, for example, sperm cells, egg cells, and spores in plants and parasites.
- In people, extraordinary cells called germ cells experience meiosis and at last offer ascent to sperm or eggs. Germ cells contain a total arrangement of 46 chromosomes (23 maternal chromosomes and 23 fatherly chromosomes). Before the finish of meiosis, the subsequent regenerative cells, or gametes, each have 23 hereditarily one of a kind chromosomes.
- Hence, the right answer is option C "four strings, each a combination of different colors"
