Answer:
Well, Earth is the same way! Earth is made up of several different layers, each of which has unique properties. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.
Because the prefrontal cortex is still developing, teenagers might rely on a part of the brain called the amygdala to make decisions and solve problems more than adults do. The amygdala is associated with emotions, impulses, aggression and instinctive behaviour.
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.
Answer:
When the energy is absorbed in a chemical reaction, we can say that this is an endothermic reaction.
Explanation:
An endothermic reaction is a chemical reaction that absorbs energy instead of releasing energy, like exothermic reactions.
To be considered an endothermic reaction, the chemical reaction must have a low energy reagent and for that reason, they need to absorb energy so that there is a rearrangement of the reactant molecules, forming products with high energy.
