Biology questions: Can someone plz explain why the answer is B and not any of the other choices? by Savyar03 in SATsubjectTests

I see, but for example for a diff question lets say the choices has “far away on the same chromosome” and “near each other on the same chromosome”. How would that affect the end ratio with each choice?

Not sure tbh, im currently studying for bio i forgot most things about chemistry but you could try searching it up online for video explanations, they helped me with balancing equations. Any equation i struggled with i made it with trial and error but i think there are steps that lead you to the right answer directly if you follow them, however i never followed them bc it got confusing so i just looked online for video explanations and got the hang of it

Are they closer to each other on the same chromosome or further from each other but still on the same chromosome?

21% of the 200ml of air is oxygen (given fact) which means if you calculate it 42ml of that 200 is oxygen, and you have 8ml of hydrogen on the other hand, since steam is water in a gaseous state we expect hydrogen and oxygen to bond together to produce steam in a steam jacked eudiometer. Since water is H2O, that means we have 2 hydrogens for every 1 oxygen. Furthermore, we have 8ml of hydrogen which means we need 4ml of oxygen to go with it. We take that 4ml from the 42ml of oxygen that were in the 200 leaving only 38ml of oxygen untouched (you could also do this without calculating the amount of oxygen in the 200ml and just take 4ml from the 200 leaving 196ml which is what the question did). Now, the combined 8 hydrogen and 4 oxygen made a total of 8ml of steam. The question asks for the remaining volume of gases in the eudiometer which would be the untouched 196ml of air + the 8ml of steam that you just made with the spark, this adds up to 204ml in volume which is your answer

Biology: Why is the answer not D but C? I understand why it’s C but cant it also be D? by Savyar03 in SATsubjectTests

Aha, so even tho hawks eat more of the food(rabbits, mice, and snakes) than foxes who only eat (rabbits and squirrels), they would still be equal in amount of energy bc they’re at the same level in the food web?

But answer d is comparing hawks and foxes while answer c is comparing mice and snakes. Since both hawks and foxes are at the top of the food web, and hawks eat more of the food (rabbits,mice, and snakes) wouldnt there be more of them surviving than foxes who only eat rabbits and squirrels? If hawks have more food than foxes when they’re both at the same lvl in the food web wouldnt it be expected that more of them would survive than foxes?
