Help Me With My Ap Bio Hw

Please help with this AP bio HW Q?

You would have to increase the organisms that eat the algae. The zooplankton feed on the algae and the small fish feed on the zooplankton. You could increase the top predator to eliminate the small fish and this would cut down on the loss of zooplankton. Of course the top predator would run out of food so you would have to add some small fish over a period of time to keep them from starving.

AP Bio HW help!!?

I did research but the answers didn't make sense or weren't complete so I need help. Here's the question:

What is Life history strategy (reproductive diapause)?

How does it relate to the concept that reproduction and rearing of offspring require free energy beyond that used for maintenance and growth. Different organisms use various reproductive strategies in response to energy availability?

Ap bio hw please help?

The answer is always C!

Help me with my AP Bio hw!?

Here is the question: Ethylene is an organic compound produced by ripening fuirts. in a controlled experiment, researchers found that ethylene gas-stimulated the ripening process in newly harvested fruit. Which of the following describes the most likely connection between natural ethylene production and fruit ripening

Just Checking some Answers on my AP Chem HW?

3. Given the heat of reaction, DHo = -1796.2 kJ, and the indicated heats of formation, determine the heat of formation of (CH3)2NNH2(l) in kJ.

(CH3)2NNH2(l) + 4 O2(g) à 2 CO2(g) + 4 H2O(g) + N2(g)

DHof CO2(g) = -393.5 kJ
DHof H2O(g) = -241.8 kJ

k so for this one all i did was -1796.2kJ = (-393.5 + -241.8) - x and solved for x and got -1160. 9 kJ would this way be correct or am i completely off?

4. Calculate DHof (kJ) for the following reaction from the listed standard enthalpies of formation:

CO(g) + NH3(g) à HCN(g) + H2O(g

DHof CO(g) = -110.5 kJ
DHof NH3(g) = -46.1 kJ
DHof HCN(g) = +135.1 kJ
DHof H2O(g) = -241.8 kJ
i did the same thing for this one as i did for three and got 49.9kJ

5. Given the following equations and DHo values, determine the heat of reaction (kJ) at 298 K for the reaction:

3 N2H4(l) + 4 ClF3(g) à 3 N2(g) + 12 HF(g) + 2 Cl2(g)

2 ClF3(g) + 2 NH3(g) à N2(g) + 6 HF(g) + Cl2(g) DHo/kJ = -1195.6
N2H4(l) + O2(g) à N2(g) + 2 H2O(l) DHo/kJ = -622.4
4 NH3(g) + 3 O2(g) à 2 N2(g) + 6 H2O(l) DHo/kJ = -1530.6

for this one i treated it as a summation problem coming up with the equation 2a + -(3b) + -(c) which is 2(-1195.6) + -(-622.4 * 3) + -(-1530.6) = -2054.6kJ


Are any of these right!? please respond!

Please help with AP Bio Hw! The G for the new reaction?

The answer is E.

The enzyme does not affect the energy situation.
The delta G refers to how FAR the reaction will go,
how much of X will be converted to Y, for example,
but has nothing to do with the speed of the reaction.
The enzyme, on the other hand, only influences how FAST it happen,
and has nothing to do with determining the resulting products.

The delta G of a reaction is the same whether or not the reaction is catalyzed,
and whether or not it ever actually happens.

Help for biology hw please choose one out of the 4?

Muscle cells in athletes often have more mitochondria than muscle cels in nonathletes. Based on this observation, it can be inferred that the muscles cells in athletes
1.have a smaller demand for cell proteins than the muscle cells in athletes
2. reproduce less frequently than the muscle cells of athletes
3. have nuclei containing more dna than nuclei in the muscle cells of nonathletes
4. have a greater demand for energy than the muscles cells of nonathletes

Can someone help me with my ap bio hw?

first define interspecific competition
Interspecific competition, in ecology, is a form of competition in which individuals of different species vie for the same resource in an ecosystem (e.g. food or living space). The other form of competition is intraspecific competition, which involves organisms of the same species.

If a tree in a dense forest grows taller than surrounding trees, it is able to absorb more of the incoming sunlight. However, less sunlight is then available for trees that are shaded by the taller tree, thus interspecific competition. An example among animals could be the case of cheetahs and lions; since both species feed on the same prey, they are negatively impacted by the presence of the other because they will have less food. Also, lions sometimes steal prey items.

Competition is only one of many interacting biotic and abiotic factors that affect community structure. Moreover, competition is not always a straightforward, direct, interaction. Interspecific competition may occur when individuals of two separate species share a limiting resource in the same area. If the resource cannot support both populations, then lowered fecundity, growth, or survival may result in at least one species. Interspecific competition has the potential to alter populations, communities and the evolution of interacting species. On an individual organism level, competition can occur as interference or exploitative competition.

How much homework do u usually have in ap biology?

The question about college credit depends on your school. If the instructor of the course has a Master's degree or higher in biology (not in education), then it is possible that they can submit their syllabus to a college, and if the administrators approve, the instructor would be certified to teach a college level course for credit. As a result, high school students could participate in what is called a "dual enrollment" program and earn college credits while taking the class at their home high school. I did this my senior year for U.S. History and ended up getting six college credits prior to my graduation. Otherwise, you will have to just take the AP Biology exam, administered by the CollegeBoard in May.

Homework/course work in AP biology....I'm currently a biology major in college, but I took AP in my senior year. I ended up getting the highest grade in my class....but let me say, there was hardly any REQUIRED homework assignments. This does not mean, however, that you do not have homework. You need to really study your notes every night, read your textbook, take notes from the text, work problems at the end of the text or as supplied as additional sources from your instructor, and even do a little research on your own from time to time. Our AP class was extremely hard...no one got away with just doing the minimum amount of work...you need to be dedicated to the course. You need to love science and biology, in particular.

Good luck!

I am going to be a senior next year. Should I take AP Lang, AP Bio, or AP Chem?

I just finished my junior year and I took AP Chem and AP English Language. From my experience AP English is pretty helpful.The majority of people whine about taking English and say it's just a class where you basically use big words to impress the teacher, but in reality it gives you a much better command of the English Language while also teaching you how to persuade people very well with your words.AP CHEM.. At my school we have probably the hardest teacher possible so that was the biggest factor for me. The AP Test definitely covers a wide range of Chemistry and you HAVE to pay attention to EVERYTHING. You'll get more confused as you go if you don't.All in all, you should check with the people at your school and see if the teachers for the subjects are actually GOOD teachers. For AP Classes you want the best teachers possible.You may also consider taking more than one. It just depends on your work load.My high school counselor always said to imagine AP classes as 2 hours of HW on average daily. This isn't always the case but it puts things into perspective.
