Mutations occur in both germ cells and somatic cells, but the consequences of both are different. Mutations in somatic cells are called somatic mutations. In this case, if mutations occur in somatic cells, they can develop diseases, or start the cancerous process. They give rise to all non-germ line tissues because they do not occur in cells that give rise to gametes.
In addition to this, a process known as teratogenesis may occur, which may end up with congenital defects, disorders, and syndromes. During the process, genetic changes may cause alterations in the baby during the embryonic phase of the pregnancy.<span>

Answer:
All of the options supplied describe the reasons for the extinction of dinosaurs and other species over 65m years ago.
Explanation:
When an impact event happens, the enormous kinetic energy of the asteroid or meteorite – a massive body travelling at high speed – is partly transferred to the Earth but largely converted into heat and sound, creating pressure waves travelling radially outwards from its centre, similar to that of an atom bomb.
As well as this blast created on impact, large amounts of dust can be kicked up into the atmosphere – like a nuclear winter – blocking out sunlight and preventing plants from photosynthesising, which has a knock-on effect to much of the rest of the ecosystem.
Answer:
Explanation:
The human body stores energy through different forms. One of it is by organic food molecules that contains sugar, fat and proteins which are rich sources of energy. Whenever the body doesn’t have enough energy to pull through, it uses these reserves of energy. The molecules start a smart process because instead of releasing all the energy at one, it slowly releases little by little in a process called oxidation (for the body not to run out of energy at once).
