Answer:
Guessing its unsaturated.
Explanation:
A fully saturated <u>compound</u> contains <u>no double or triple bonds</u>. Alternatively, if a <u>molecule</u> <u>contains double or triple bonds</u>, it is considered to be unsaturated.
B) Cytosine and guanine.
The pairs are A/T and C/G.
Answer:
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
Explanation:
Alpha decay:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
Answer: Originally viewed as a single event, the Taconic orogeny is now known to consist of at least three episodes. The first took place in the Early Ordovician Epoch near Maine and Newfoundland. The second was centred on eastern Tennessee in the Middle Ordovician Epoch.
