Answer:

RAM

RAM = (mass \: of \:  ^{28} Si \:  \times \%abundance) + (mass \: of \:  ^{30} Si \:  \times \%abundance) \\ RAM = (28 \times 90\%) + (30 \times 10\%) \\ RAM = 25.2 + 3 \\ RAM = 28.2

What are the nitrogen bases that make up the DNA molecule and how do they pair up?
wariber [46]

There is a second nucleic acid in all cells called ribonucleic acid, or typically known as RNA. Like DNA, RNA is a polymer of nucleotides. Each of the nucleotides in RNA is made up of a nitrogenous base, a five-carbon sugar, and a phosphate group.

I really hope this helps, and I'm sorry if it doesn't It would be great if you posted the answer choices too.

Why is water clarity an important measure of water quality?
Neko [114]
Water clarity is important in water habitats. The amount of sunlight that reaches underwater plants depends on water clarity. The plants will die if they cannot get enough sunlight, and we need the water to be clean and clear so the sunlight reaches the plants. Hope that helps :)

Analyze. This reaction releases energy as heat. Explain whether the reaction is exothermic or endothermic and whether it obeys t
BartSMP [9]

Answer:

See explanation

Explanation:

If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.

Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.
