Answer:
A. predation.
Explanation:
Predation is a type of ecological interaction in which one organism which is known as predator feeds upon another organism thereby killing it. The organism which is killed by predator is known as prey. In such interaction one organism is benefited while another one is harmed.
Brown bears of Alaska feed upon salmon. In order to so they have developed many ways which include waiting at the bottom of falls from where salmons pass by or standing at the bottom of the falls.
E) mass defect
This is so because the mass defect is the difference between the particles of the nucleous weight and the nucleous itself. According to the equation E=mc^2, the mass defect is related the the binding theory. In order to calculate the mass defect of an atom you need to add up the masses of each proton and each of neutron that are present in the nucleus and then you substract the actual mass of the nucleus from the combined mass.
1. The name of this element is Carbon because there are 6 electrons in the shell.
2. Sorry I didn't learn that. And I don't know.
1. A metal is a solid substance, usually hard. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.
2. When a new substance is formed at that time we can understand that chemical reaction has taken place. It can't be reversed.
4. Neutron = no charge
Electron = negative
Proton= positive
5. Nucleus has a positive charge.
6. An atom is bigger. Because electrons are what takes up space in atoms, the result is that the size of the biggest filled orbital determines the size of the atom or ion.
