We have a boiler and hot water heating system. Our basement is very, very warm. My question is, will covering the copper piping with insulation allow more of the hot water into other areas of the home and lower our heating bills?

1- Describe the structures of the 3 types of lipids.
2- Define & Describe the structures of a liposome,a micelle, & a phospholipid bilayer.
3- How do ions cross the lipid bilayer of the cell membrane?
4-What are 6 ways substances are transported into a cell?
5- Why can osmosis only occur if solutions are separated by a selectively permeable membrane?
6-Why do phospholipids organize into a bilayer in an aqueous solution?
7- What part of a lipid molecule is in the middle of a lipid bilayer?
8-Why is the sodium potassium pump called an electrogenic pump?
9-Why is it that when biomedical researchers design drugs that have to enter cells to be effective, they sometimes add methyl (CH3) groups to make the drug molecules more likely to pass through plasma membranes & enter cells?When researchers design drugs that act on the outside of the plasma membranes,sometimes charged groups are added to decrease the chances of the drugs passing through the membranes & entering cells?

Thanks!

Can you help me to solve the following simultaneous equation's
5x + 3y = 52 and 7x + 11y = 100
11x + 8y = 62 and 23x + 12y = 106
2x - 5y = 62 and 7x - 3y = 60
15x - 19y =22 and 20 x - 23 y = 34
4x + 7y = 49 and 11x - 5y =62
7x + 6y = 72 and 9x - 8y = 14
If you can give me step by step explanation's as you go that would be great. Thankyou

Could someone please explain to me in really simple terms what is ment by acid dissociation.

Thankyou!


also, any ideas as to why I would get acidic readings of 5.43 and 6.43 when I measured the pH of two very weak NaOH solutions (diluted with distilled water) - is this caused by dissociation?
