Correct answer: A. Alpha particles are 20 times safer than other types of radiation.
Alpha, beta, gamma, and X-rays are the forms of ionizing radiations. Alpha radiations are emitted when an atom emits alpha particles with 2 neutrons and 2 protons. These particles ionize matter due to their charge and mass. Alpha particles cannot penetrate the outer layers of the skin, but when present inside the cell they can be very damaging as they lose their energy within short distances ionizing the matter present around. Therefore, alpha particles cause more damage than other forms of radiations.

Answer :
No, <u>we cannot</u> stir silver nitrate solution with a copper spoon <u>because</u> , copper is more reactive than silver. Thus,it would displace silver from the silver nitrate solution forming copper nitrate.

Answer: Reaction A: pi + glucose ⇒ glucose-6-phosphate + H2O ΔG = 13.8 kJ/mol
Reaction B: pi + frutose-6-phosphate ⇒fructose-1,6-biphosphate + H2O ΔG = 16.3kJ/mol
Explanation: ΔG is the representation of the change in Gibbs Free Energy and relates enthalpy and entropy in a single value, which is:
ΔG = ΔH - TΔS
where:
ΔH is enthalpy
T is temperature
ΔS is entropy (measure of the )
It can also predict the direction of the reaction with the conditions of temperature and pressure being constant.
When the change is positive, the reaction is non-spontaneous, which means the reaction needs external energy to occur. If the change is negative, it is spontaneous, i.e., happens without external help.
Analyzing the reaction, we see that reaction A and B have a positive ΔG, while reaction C is negative, so the reaction that are unfavorable or nonspontaneous are <u>reactions A and B</u>.

Explanation:
in saturated fats there is no double bond between the acids and are tightly packed and unsaturated fats arent tight and loosely packed/put together
saturated- solid at room temperature
unsaturated= liquid at room temperature
two types of unsaturated fats, Polyunsaturated fats and Monounsaturated fats
