The tiny structure inside a seed is called the embryo. The embryo will develop into the plant.
A. Because elements are made up of atoms, neither electrons nor protons
Answer: Typically, the more massive the planet, the more massive the atmosphere it can acquire and maintain.
Explanation:
But a planet's size is not necessarily proportional to its mass. In the end, how massive a planet is has more to do with its composition and density. So while a planet like Mercury may be smaller in size than Jupiter's moon Ganymede or Saturn's moon Titan, it is more than twice as massive than they are.
1. Electrons travel around the nucleus in fixed energy levels with energies that vary from level to level
2.protons, neutrons, and electrons have a mass, but electrons have far less mass
3.cations and protons
4. idk
