The pair of magnets and a pair of water molecules are most likely similar. It is because the pair of magnets connects positive to negative and negative to positive, which is also similar to water molecules where they also connect to positive to negative.
Answer:
Myelin sheath increases the speed of electrical impulse along the nerve cells.
Explanation:
Myelin sheath is an insulting layer of proteins and fatty acids that are present around the nerves of brain and spinal cord.
Myelin sheath increases the speed of conduction of nerve impulse from one nerve cell to another cell. Myelin sheath is formed by the concentric wrapping of schwann cells around the axon. This sheath decreases axonal membrane capacitance and increases the conduction of nerve impulse.
Catalysts increases the rate of a reaction by lowering the need for a larger reaction. Basically, the more reactions that are created, the faster the rate of the reactions will become. An example of this is Amylase in our saliva.
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.
I think it might be B. Nothing was compared.
