So imagine that you have a new drug that makes humans learn better. This drug that you have can work on receptors at synaptic terminals, but does not necessarily have to. You have to determine what are the proteins that this drug works on. To prove this you need to design 5 sets of experiments that test this. Experiments can be independent or it can be one experiment that builds on itself. ----I was thinking of using fluorescent technology to show that the protein dealing with the drug is activated in brain... or maybe since the drug does not have to to work on receptors at synaptic terminals, then maybe i can use a reporter gene to …

What would happen if 4-methyl-2-pentyne was reacted with ozone and water? I believe that ozone would cut the triple bond, but that's as far as I've gotten. Help please?

Hello all, this is a question I have on a practice exam. If the glucose is labeled with C-14 at the 1-position, what fraction of the isotope will not have been released after each two-carbon fragment has gone through four complete turns of the cycle? The answer: Glucose labeled in the 1-position will produce methyl-labeled acetyl CoA. After four complete turns, one fourth of the input-labeled carbon will be present in oxaloacetate. I have read the Lehninger "Principles of BIochemistry" textbook many times on how to go about reaching this answer but I still do not understand. please help!

This might sound a little odd, but I need to interview someone who is in the environmental science field. I am taking a human development class for career exploration, and I need to interview someone that is in the field of work that I am interested in. The person that I had lined up cancelled on me today, and it is too short notice to get a hold of anyone else in my area. My paper is due this Friday. I've looked around online and I'm hopeful that someone in this community would be able to give me some of their time. I'm not sure what specific field I want to go into, but so far I've come up with Park Ranger (or something along those lines) or working for Fish and Wildli…

I would be very greatful if someone could point me in the right direction. While I understand this to be the execute sequence for a PUSH in register transfer language: [AC] --> ALU --> ALUB [ALUB] --> MWB [sP] --> MAR [MAR] --> Address decoder [MWB] --> M [sP] + 1 --> SP I am unsure as to the POP instruction. Would it be the opposite of the push i.e. [sP] - 1 --> SP M --> [MWB] Adress decoder --> [MAR] or is this completely wrong. Any help would greately appreciated.

1. Whatis the concentration of 50 mM(milimoles) CaCl2 when expressed in %(w/v)? (Assume the Mr of Ca = 40 and Mr of Cl is 35.5) I got the RMM as 111 which i then halved and got 55.5, would I be right in thinking that it would then be 55.5% (w/v) ? Thanks in advanced for any help!

Hi everyone! I need some help with this survey for my thesis. Thank you so much! surveymonkey.com/s/5JKP9VK

hello, Im having trouble with these Stat II questions. Think you guys can help? Attached in a pdf file Thanks Paired-T.pdf

A gas is confined in a cylinder by a piston. The initial pressure of the gas is 7 bar(700kPa), and the volume is 0.10m^3. The piston is held in place by latches in the cylinder wall.The whole apparatus is placed in a total vacuum. What is the energy change of the apparatus if the restraining latches are removed so that the gas suddenly expands to double its initial volume, the piston striking other latches at the end of the process? Data known: P(initial) = 700kPa V(initial) = 0.10m^3 V(final) = 0.2m^3 My analysis: Since the gas suddenly expands (not a quasi-equilibrium process), the PV ln (V2/V1) equation cannot be used. But still, my lecturer gave me zer…

Hi guys, Here is my question/statement I need you to answer. I need the materials and procedure You have been asked to separate the contents of a barrel. The barrel contains sand, motor oil, water, gravel, small pieces of metal, and pieces of cork. Develop a procedure and materials needed to separate the contents of the barrel.

So what I did was just added the two vectors (10 i + 20j) + (-5i + 10J) and got 5i + 30j . Since a= Fnet/ m I divided 5i + 30j by 5 and got i + 6j (a). However I'm not confident about my answer because it seems too straightforward.

Question is in attachment So the formula I used was F= ma = F= mdelta v / t 10i + 20j = 5 kg(Vf-(-5i+30j)/10 I got 10i +20j = 1/2vf( -5/2i+15j) = (15i + 70j)m which is C. However the question says the object is located in the origin of reference frame and asks to find the position of the object which I don't understand how to do :/ Oh a piece of the question got cut off. The question is "What will be the position 10 seconds later"?

Hi, i would like some help on this question that was given to me for revision for my exam in a couple of days. A 20,000V overhead power line carries 50kW of power. Calculate the strength of the magnetic field at a point 12 metres away from the power line and give the unit for your answer. the value of k is 2.0 x 10-7 TmA-1 (to answer this question you will need to first calculate the current in the wire) That is what the whole question says. I haven't learnt anything like this, this year so please help me out. thanks in advance.

An air compressor is used to compress air from 100kPa and 30°C to 800kPa at a rate of 120kg/min. By having the inter-cooling feature the compression is done at constant temperature of 30°C. Calculate the power required for the compression. Known data: P(initial)=100kPa P(final)=800kPa Temperature(constant)=30°C Mass flow rate=120kg/min=2kg/s My friends applied the formula of work done for isothermal process(since the compression is done at constant temperature of 30°C): W=RTln(P1/P2) *R used is 0.2870 Their assumption is that Work(in)=Work(out). May I know what happened to the mh1 in the usual energy balance for open system? Under what condition can we ma…

Do the subtraction of 11000-01001 in two's complement. So I have to convert the "01001" in two's complement and then add 11000 to it...So basically is -24-(+9) and the result should be 33 but what I get isnt 33..help :/

This is more than likely, going to sound like a dumb question. I am trying to come up with a great answer to why I am finding an abundance of bacteria in comparison of fungi. I have the basics in the answer, pH, slower incubation time, general higher abundance in the environment. Anything else anyone can help me with? Much appreciated!

Greetings everyone! As the title says, I'm having trouble in solving this problem. For a system formed of a stationary electric pole and a stationary magnetic pole, the electromagnetic angular momentum is independent of their separation distance. I've managed to prove this (and calculate the angular momentum explicitly) but I'm having trouble in answering another question, namely to prove that the electromagnetic linear momentum density has 0 divergence by writing it as a curl. It is easy to calculate the divergence explicitly, but I have no idea how to find the vector having as curl the linear momentum density. Right now I'm mostly trying various quantities, my best res…

Here is my assignment: Draw resonance structures to show in which position nitrobenzene will nitrate to form dinitrobenzene. I know that nitro groups are meta-directing, so the product will be m-dinitrobenzene. So do you just draw an intermediate carbocation with the charge in the meta position? If that's the case, where is the resonance? Would I show the charge being in the ortho, para, and meta positions but then indicate that the meta position is the most stable and therefore where substitution will occur?? I'm not fishing for just the answer, I want to make sure I understand this right, so any advice is helpful, Thank You!

I have created an html file that utilizes a library. The library stores the calculation function of dew point and wind chill. The goal of this file is to input temperature, humidity and wind and to produce the outputs of either dew point or wind chill. I am having trouble getting the output to come up at all. The following is the code for my library, saved as weather.js: function CalculateDewPoint(dew) // Assumes: the temperature is measured in degrees Fahrenheit, humidity is measured in relative humidity // Returns: the corresponding due point will be calculated in degrees Fahrenheit { var dew; dew = temp - ((100 - humid) / 2.77…
