Ok so I have a project and I have to measure the sidereal synodic rotation period of the sun using sun spots. I have included a diagram of what to do. but I will explain it too. you take 5 images with a common sunspot and track it's movement on those 5 days (on the diagram, the sunspot is...
A star exhibits a parallax of 0.250 arcseconds when measured from Earth.
a) What is its distance (pc)?
I know this uses the formula d=1/p, so i can solve this very easily
b) What would its parallax be if measured from Venus’s orbit (arcseconds)? (Look up
the one parameter you need to...
the half life of C14 is 5730 years. if a sample of C14 has a mass of 20 micrograms at time t = 0, how much is left after 2000 years?
I learned from somewhere that these exponential decay and half life problems use the equation
y = ab^t or y = a(1+r)^t
where y = total, a = initial...
is it true that as the lipid water partition coefficient increases, the permeability of lipid increases and the permeability of water lowers. does that mean that a substance w/ a high lipid water partition coeffecient will be able to go through the cell membrane more easily and cause hemolysis...
in this picture, there is a legend with the terms LINE and SINE in it
http://i.imgur.com/IGJfm.png
what do the terms LINE and SINE mean? I mean what do they stand for and what is their purpose in DNA. I have tried to look them up but it keeps going to math.
here is a link to the procedure of the experiment, but i don't know what the purpose of this is...like in practical life what is it used for.

I though the mRNA was altered and stuff before the final protein product was made, but is DNA also altered because it's like a protection mechanism or something?
thanks
if you are in university then you will have to log in from your university email address and then use the library services to be able to get journal articles for free, if you are not doing that then you will not be able to access anything related to your lab report free. sometimes google scholar...
hello
i was just wondering what is considered to be the finger print region in an IR spectrum. Is there a range of wavenumbers which are designated as the finger print region?
...let me clarify um so a C-O bond in an ether (and maybe alcohol) is suppose to have a peak in the 1000-1200cm^-1...
what is the difference between neoteny and post development
according to my lecture
neoteny = early maturation of gonads in larva that then stops growing and never becomes an adult
post development = onset of a developmental process is delayed relative to reproductive maturation...
Two Work-Study students were hired to check and test the reproducibility of some new
experiments and of the new polarimeter. Student 1 prepared three samples of
the same resolved amine by repeating a resolution experiment three times. Student 2
performed three measurements of the specific...
so this is for my lab report for ecology. i need to have a figure showing at least 1 stat test.
the hypothesis i am trying to prove is that diversity of birds will be greater in disturbed areas (like with human influence) compared to woodlot (like forest and such)
from the data...
