At 25°C, when 4.2 gram of iodine is dissolved in a mixture of 100 ml of water and 100 ml of carbon tetrachloride, there are 0.05 gram of iodine in water and 4.15 gram in CCl4. What is the distribution coefficient Kd = Co/Cwater between water and CCl4 at 25°C?

Please help? Thank you!

Select the options below that occur during the process of translation, and indicate the order of steps using numbers

__ TRNA matches a codon on mRNA

__ MRNA binds to an amino acid

__ stop codon is recognized, and triggers mRNA release

__ an amino acid is added to growing peptide chain by peptidyltransferase reaction

__ an amino acid is added to the growing peptide chain by phosphotransferase reaction

__ an AUG codon binds to ribosomes to start translation

__ and UAG codon binds to ribosome to start translation

Hi, I'm considering applying to Northeastern's school of pharmacy (Bouve College of Pharmacy) for the fall 2015 admission. I currently go to an undergraduate college and will be a senior this fall. I would be applying to NEU's pharmacy school as a P1 transfer student. This school, along with Albany College of Pharmacy & Health Sciences, are my top choices. The thing is, Albany College of Pharmacy has an early decision deadline on Sept. 1st. But if I do this and get accepted, then I can't apply to Northeastern, which is why I want to know if I even have a shot to get into NEU's pharmacy school (which is more competitive) based on my current stats. I honestly want to know what you guys think if my stats are even remotely good enough to be accepted to NEU pharmacy. If not, then I don't see why it would be worth applying when I may have a better chance at Albany College of pharmacy. As a matter of fact, I would also want to know if you guys think I should (or should not) do early decision for Albany if my stats are not up to par for NEU pharmacy? I just really want to know what you guys think and really want an honest opinion, because I feel like I'm in a bind here, since it's really whether I do Albany's early decision which is soon (Sept. 1st) or NEU's pharmacy school which would probably get back to me in weeks after the Sept. 1st deadline for Albany.

The Guinness world record for underwater breathing record (for a human), which was done by breathing 100% O2 for 30 minutes before the dive, resulted in a breath-holding record of 20 min and 21 sec. What problem does 100% O2 solve?

What is different here from humans “free diving” (with records of 11 min and 35 sec)? Or a sea turtle submerged for 10 hrs. and 14 min?

Please help, thank you.

You are in the water with your head just above the water line. The waves have amplitudes of 3 meters, wavelengths of 10 m, and speeds of 30 m. How high above your chin is the wave crest when you are in the deepest part of the trough? How long before you are in a deep trough again? Please explain, thank you

I know that blood pressure declines after it crosses a capillary bed. But what happens to blood pressure after it leaves the heart? ...I would think pressure would decline once blood leaves the heart and enters the aorta, arteries, etc. What do you think? Can someone please explain? Thank you.

Salmon migrate from cold pacific waters to potentially warmer inland lakes and rivers. What is the difference in O2 availability for the salmon? Can someone please give me an explanation? Thank you.

My professor asked us this, but I could not find the right type of information I'm looking for. Can you please explain this so can know? What are some examples of cells and how do they differ, etc. Please answer this, Thank you.

She says:

2- Be able to list specific examples and discuss the ultrastructural (electron-microscopic) and light microscopic appearance of (a) a protein-secreting cell, and (b) a steroid (lipid) secreting cell. Also, understand the ultrastructural (organelles) differences between cells that are active in secreting proteins, as opposed to those that synthesize proteins but do not secrete them.
