That's all the information the book includes. The rest continues with what you mentioned above regarding voltage gated K+ channels. However, I understand what you are saying. Thanks for the help.

Sorry I may not have been clear enough. I understand everything you have said. I have attached a photo of the exact sentence in the textbook. How does this have anything to do with requiring a larger-than-normal stimulus or the relative refractory period?

Hello, Quick question on the relative refractory period in neurons. I understand it is caused by the slow closing of voltage gated K+ channels, which leads to hyperpolarisation. This means a larger than normal stimulus is required to bring the membrane to threshold. However, after reading my...

Thanks guys you were extremely helpful!

Hey guys. When a polysaccharide (e.g. starch) is made I understand that monosaccharides are linked together and a water molecule is removed. In the final product the polysaccharide has a mass of n times its empirical formula plus a water molecule. Like the mass of 300 starches from 300 glucose...

Thank you so much! Can't believe I missed that.

Homework Statement A manufacturer makes a batch of n items with the cost (in dollars) of each item being: n2-6n+35. The manufacturer sells the items for $50 each. How many items should be produced in each batch to maximise profit. Homework Equations Cost = C(n) = n2-6n+35 Revenue = R(n) = 50n...

What I meant was why the nucleons need to release energy. But I now understand that they actually need to release energy to 'slow down' and bond together.

So I was wondering why do nucleons need to remove mass to form a nucleus. Is it because it lowers the energy of the nucleus making it more stable or something completely different. I understand that it is the energy input to break the nucleus into its components, however, why do nuclear reaction...

Homework Statement We are asked to calculate the comparison rate of an offset loan. Loan amount = $735000 Offset amount = $100000 Original term length = 300 months Offset term length = 254 months Original repayments = $4228.50 Adjusted Repayments (for comparison rate) = $4224.57 Total amount =...

Hey guys, I as wondering what happens to an insulator during and after electrical breakdown. I understand that at a high enough voltage it exceeds the dielectric strength and becomes a temporary conductor. However, what happens afterwards. Is the material deformed or does it still maintain...

Thanks so much. I thought as much after a few hours that this was impossible to solve manually.

Homework Statement The problem ask to calculate the interest rate of a loan. The principal is $735 000, term is 25 years (300 months), and the repayments due is $4656.17/month. i = interest rate, PV = present value, R = repayments Homework Equations PV = R x [(1+i/12)^300 - 1]/(i/12) The...

Hey guys, Can anyone help me think of some relevant physical (8 or so) and chemical properties (5ish) required by flag poles. I was struggling to think of some but here are some of mine: Physical Flexibility Elasticity Melting point Strength? Electrical conductivity?? Chemical Stability UV...

Never mind guys. I figured it out.
