A major positive is that a life on earth could not exist without the greenhouse effect. If the atmosphere did not retain heat, our planet would be in habitable to plants and animals. Carbon dioxide is a greenhouse gas, but it is. Pretty much the weakest one of their is. All other greenhouse gases are turned in how many times more effective the gas is then carbon dioxide. Water vapor and sulfur oxides are some examples of more potent greenhouse gases.
The energy of nuclear fission is released as kinetic energy of the fission products and fragments, and as electromagnetic radiation in the form of gamma rays; in a nuclear reactor, the energy is converted to heat as the particles and gamma rays collide with the atoms that make up the reactor and its working fluid, ...

Answer:
Explanation:
In mirror generally, the type of image that can be formed by an object placed in front of it can either be a real image or a virtual image. Virtual images are images that are formed behind the mirror.
Virtual images are also images that cannot be formed from a photographic screen i.e the image formed by an object in front of the mirror cannot be reproduced compare to a real image than can be formed on a screen. This is the reason why we are able to get a picture of our self when pictures are taken using a photograph (For real images). This is not the same for virtual images.
We can only see ourselves when we stand in front of a mirror but in actual fact, we cannot reproduce the image of us we are seeing in the mirror.
The answer is a. endothermic.
In endothermic reaction, as the name suggests, the reactants require energy absorption to form and complete the chemical reaction to form products.
And even if you don't know the answer, you can exclude all other answers by scientific logic and you will be left with the correct answer.
Hope this helps.
