Errors in Biology Destroyer

On 2009 Destroyer, 212 - I believe there are two false statements A and B
A. THe pH of the cytosol is more acidic than the lysosome
B. Lysosomes are found in both Plant and animal cells

220. Isn't this a false statment?
b) If two organisms occupy the same niche, they will mate at the same time of the year.
Isn't this false?

This isn't related to the title but I've got

Achiever 1
Bio - 15
Chem -18
Ochem - 18
PAT - 18
Reading 18

I'm very worried about Biology.. yeah I took at after reading Kaplan and Cliff AP but not Destroyer but it's VERY low..
I hope Achiever is like 4 points harder so I can at least get 19 on BIO

Yes 212 should be both false, but 220 is true since of organisms do the same thing in the enviroment chances of the mating at the same time are higher

I believe this is true: Lysosomes are found in both Plant and animal cells

You can see the lysosome in this pic: http://www.sparknotes.com/biology/cellstructure/celldifferences/section1.html

Also, I've found a bunch of other sites that say this is true. not willing to pull out Cambell's..but I would think it's in there as well.

I am pretty sure 220 is true too. Neither of those are mistakes.

Yea i agree here. First of all, I thought lysosomes were'nt in plants either but apparently they are. Just know that the plant cell, has everything an animal cell has besides for centrioles (although I believe they do have some other microtubules)

And for the second one.. if they occupy the same niche they will most likely compete for the same food sources eventually driving one towards extinction. And as BB said, they do mate at the same time of the year since they do the same things pretty much.

And don't worry about those scores too much. The Bio on the Acheiver only gets harder lol. Honestly, the best resource is Cliffs. Read it up and make corrections!

Good luck

I have to agree. If two organisms occupy the same niche, then their chances for mating are greatly increased and they will probably mate at the same time of year.

Competitive exclusion principle states that two organisms will compete, until one is left in the niche. It seems counterintuitive to say that these organisms will end up doing the same things because they are not even permanently able to occupy the same niche. To me, I just think that theoretically..if two organisms were to compete for the same niche for a period of time..they would mate at the same time. But in reality, two organisms cannot fully occupy the same niche for a long period of time..or at least that's what competitive exclusion seems to say.

 

[TooQuickSlick]

It says organisms not species, so I think its meant to infer that the organisms that share the same niche are the same species. Because no two species can share the same niche. There are lysosomes in plants? I thought they used vacuoles.

On 2009 Destroyer, 212 - I believe there are two false statements A and B
A. THe pH of the cytosol is more acidic than the lysosome
B. Lysosomes are found in both Plant and animal cells...This is a true statement. Plants have modified Lysosomes, known as Glyoxysomes. These organelles are predominantly used by germinating seeds to breakdown proteins and provide their required energy.

220. Isn't this a false statment?
b) If two organisms occupy the same niche, they will mate at the same time of the year.
Isn't this false?
If two organisms occupy the same niche, they can be from two different species, which means the level of competition between them is most likely minimal. In other words, they don't compete over limited resources (which include mates). Thus, they can very well mate at the same time of the year and still have no problem (intense competition) over finding mates.

Achiever is much harder than what you'll ever see on the real test. So don't freak out too much, if you're not scoring as high as you're expecting.

Yes, the two organisms can be from different species, but that certainly does not mean that th level of competition between them will be minimal. If two organisms occupy the EXACT same niche, one of them will be either forced out of the niche or forced into extinction... and they definately DO compete for the SAME limited resources, hence "the same niche". Obviously if they are from different species mates would not be included as a limited resource, but that is irrelevant.

As far as the question of whether being in the same niche automatically means that they mate at the same time of the year... I'm honestly not sure, sorry. I personally would have guessed yes, but i really don't have any solid reasonging to back that up 😳

If two organisms are from different species, the level of competition (at least in terms of finding mates) is minimal, because by definition two different species are those that are reproductively isolated! And how could you say mating is irrelevant, when this question is focusing on reproductive behavior of the organisms and nothing else?!

I think you misread the question. It's not asking whether mating of two different species will be altered because of the fact that they occupy the sam niche.

It's asking whether or not, because of the fact that they occupy the same niche, they will necessarily mate at the exact same time of the season. For example (not a real life example), if you have a species of deer and a species of elk that occupy the exact same niche, does this fact mean that they will both be in mating rut/heat in the fall.

OBVIOUSLY they won't be mating outside of their own species, but THAT is irrelevant to the question. The fact that they won't be in competition for mates has no bearing as to whether their reproductive cycles will be in sync.

I looked it up. Lysosomes are occasionally found in plant cells. its rare because in plant cells the vacuole usually does what a lysosome does in an animal cell but lysosomes could be found in plant cell. http://www.cellsalive.com/cells/cell_model.htm

Thank you guys for replying to my question.
According to Cliff's AP Bio, "The presence of lysosomes, centrioles, and cholesterol in animal cells and their absence in plants." p.38
And also in Campbell Biology 7th ed page 100 has the same thing.
What do I do if get this question on the DAT???

fight it! jk..GO WITH CAMPBELL!! I would

Lysosomes are mainly found in animal cells and rarely found in plants. So if you get a question on plant organelles, put lysosome in. But most questions with comparing plant to animals will ask more common things like centrioles, cell wall, difference in vacuoles?
