Biology
1 answer:
BabaBlast [244]3 years ago
5 0

Answer:

False, since it takes more than one million years

Explanation:

Speeds can be faster for small-scale convection occurring in low-viscosity regions beneath the lithosphere, and slower in the lowermost mantle where viscosities are larger. A single shallow convection cycle takes on the order of 50 million years, though deeper convection can be closer to 200 million years.

What are the four carbon macromolecules the body uses and makes?
aliya0001 [1]

Living things are made of types of molecules, known as macromolecules.

There are four major classes of biological macromolecules:

carbohydrates

lipids

proteins

nucleic acids

Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
