Answer:
a rain of asteroids coming from space
Explanation:
2-ethyl-4,4 -dimethyl hex-1-ene.
The correct answer is option c, that is, nucleus.
A usual atom comprises three subatomic particles, that is, the neutrons, protons, and electrons. According to Bohr's model, the majority of the mass of an atom is in the nucleus, that is, a small, dense region at the center of each atom, comprising nucleons.
The nucleons incorporate neutrons and protons. All the positive charge of an atom is found in the nucleus and arises from the protons, the neutrons are neutrally-charged, and the electrons are the negatively charged particles found outside of the nucleus.
Mass is equal to moles x molar mass, and the molar mass of C6H12 is 84, therefore the mass is 436.8 g, but 437 rounded to correct significant figures
Q1) The best description for molecule b in the diagram is adenosine diphosphate because there are only two phosphate groups. (b)
Q2) I would say b again, but I am not 100% sure. In the diagram, ATP seems to have given off a phosphate group and become ADP. The other answers are all not specified in the diagram, but rather inferences from what might be happening.
