Answer: Weak.
Explanation:
The complete question is:
Scientists use a substance called Iodine-131 to treat cancer. As Iodine-131 undergoes radioactive decay and emits beta particles, it kill cancer cells. Which fundamental force is being used in this type of treatment?
Well, here we have beta decay.
Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)
Then the correct option is the second one, weak.

Explanation:
1. Acids react with metals to release hydrogen gas
Take some granules of zinc in one glass test tube and magnesium in another glass test tube and magnesium in another glass test tube. Pour dilute hydrochloric acid in one and sulphuric acid in the second. Reaction takes place and a gas is released in each. Test the gas for hydrogen by bringing a bur…
2. Acid reacts with a base (metallic oxide) to form salt and water
HCl + ZnO → ZnCl2 + H2O Acid reacts with an alkali (hydroxide) to form salt and water. HCl + NaOH → NaCl + H2O In these Reactions acid neutralizes the base to form neutral substances like salt and water.
3. Acids reacting with Metals
The reactions of dilute acids with a variety of different metals can be investigated, small fresh samples of metals are placed in 2ml samples of dilute hydrochloric or sulfuric acid. The rate of reaction depends on the 1. Concentration of the acid – if the acid is too dilute the reaction is very slow. 2. Type of metal

Answer:
ATP and NADPH which are products of the light dependent reaction,a photo system 1 and 2, they are stored and used in the light independent reaction for the production of the carbon sugar
The nervous system is one of the most important elements for our existence and survival, since it allows the management, organization and functioning of the rest of the corporal systems.
The synapse is a communication mechanism that occurs between two or more neurons in order to massively transmit a nerve impulse in order to coordinate a function in the organism.
The Chemical Synapse is the type of major synapse in our body. In these synapses the information is transmitted chemically, through the sending by the presynaptic neuron of different neurotransmitters that the postsynaptic neuron captures through different receptors, whose action generates an alteration in the form of excitatory or inhibitory postsynaptic potential that may end or not with the generation of an action potencial by the postsynaptic neuron. They are versatile synapses, since some neurons can inhibit the action of others depending on what is activated. There is no physical contact between both neurons.
