D. Organisms specialized for living in a particular niche.
Answer:
B
Explanation:
Ribosenucleic acid (RNA) and Deoxyribosenucleic acid (DNA) are the two nucleic acids formed from building blocks called nucleotides. Although, they are formed from the same building blocks, but have structural differences.
One of the differences between RNA and DNA is that unlike DNA that is a double-stranded molecule formed by the complementary base pairing of two nitogenous bases (nucleotides), RNA is a single-stranded molecule made up of shorter nucleotides.
Answer: Option C) Triglycerides, long-chain hydrocarbon tails
Explanation:
Triglycerides are lipids, with three fatty acids (the same or different) having long hydrocarbon tails.
The hydrocarbon tails in triglycerides is the structural element that makes it insoluble in water as seen in the sample forming a separate layer on top of the water because it does not form hydrogen bonds with water molecules i.e hydrophobic
Thus, option C is the answer
The correct answer is: B) gold.
Oil, diamonds, and natural gas all form over time under significant sustained increased soil pressure. Gold's formation, however, is not due to pressure. Gold is already present in soil and must be mined in deeper layers.
Well, i think the answer is B. 51 Kilometers
If it's a scientific experiment, it's very likely that they use internationally accepted measurement, which means the result will be in a metric system
Hope this helps
