A scale is used to measure mass in grams. ☺♥
The answer to this question is the term Macromolecule. A macromolecule is termin biology and chemistry that is composed of many / thousands of atoms which is considered as a large / huge molecule. This is made by joining of small subunits to form a huge molecule.
All vertebrates are, by nature, in two classes : the male class and the female class. Only some invertebrates like the earthworm, water snail etc are in single class with both male and female organs in the same body.
The shape of the DNA molecule is called a double helix.
This is because the structure has four main chemicals that join together in specific patterns that looks like a double helix.
Hope this helps :))
