The pine question was in the Western Hemisphere, there are mountains North and South facing. South facing slopes have more shrubs/sage bushes while the North has more pine trees. It asked why this occurred. The two most popular options seem to be.
1: The slopes are steeper on the Southern mountains, so Pine trees can’t grow there.
2: The water evaporates more quickly on Southern mountains so Pines can’t grow there.
Also for the fertilizer one, are you guys sure it was nucleic acids? I chose inorganic compounds :\
@Skarlo Actually, I think the answer was nitrogen after researching it. " Fertilisers provide plants with the essential chemical elements needed for growth particularly nitrogen, phosphorus and potassium."
@Skarlo it’s definitely number two I believe. For the shrubs in the sun, the heating of water causes the water molecules to move exceedingly fast until they break free from the bonds that hold them in place as a liquid. The evaporation process happens faster which then causes the shrubbery to not grow as big and lush as pines.
@CollageWhat So is the answer choice Nucleic acids?
And following that logic is it possible to get an 800 if you missed 3 (lol). I heard the curve is almost 99% of the time 77 raw, and with 3 wrong that brings me to 76.25.
@RybkaShredder That’s because nitrogen is a component of nucleic acids. In fact the answer would work perfectly by that logic as phosphate groups in nucleic acids also contain phosphorous, the two key limiting factors being accounted for (nitrogen and phosphorous).
@Boltingflame Yeah. I thought of nitrogen and phosphorous in fertilizer, which are both constituents of nucleic acids. But are nucleic acids responsible for growth? I guess they make up DNA which controls everything, including growth?
I think the main problem is how perfectly nucleic acids fit because they contain both phosphorous (phosphate groups) and nitrogen (nitrogenous base). The main issue however is that plants (can/cannot) break down nucleic acids into these basic constituents.
On the other hand, phosphorous and nitrogen are both technically inorganic compounds as they do not contain carbon. The main issue is that the term is kind of vague I suppose and doesn’t specifically include phosphorous/nitrogen.
@foreverprongs yeah, but nitrogen and phosphorous are taken in and assimilated and used for DNA, obviously not all of it. It’s just whether that affects growth.
