The most fundamental property of a star that determines its evolution is the MASS of the star.
In fact, while low-mass stars usually end their life becoming red giants and then white or black dwarfs, the high-mass stars can evolve into red supergiants and eventually originate a supernova. After the explosion of the supernova, depending on their mass, they can becomes neutron stars or collapse into black holes.
Answer:
Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another. For example, carbon's atomic number (Z) is 6 because it has 6 protons.
(25m north) + (10m south) = 15m north
(10m east) + (5m west) = 5m east
So the bee is now 15m north and 5m east of the hive.
most carnivore live in forest because
- They are highly dependent on flesh for their food and therefore their food is easily available in forests.
- Small animals live in forests that make it the ideal habitat for carnivores.
- Carnivores help in maintaining the herbivore population at a healthy level, by hunting.
- It all helps in keeping ecosystems in balance.
