Do viruses require specific receptors to infect cells?
Yes, all viruses need to bind to specific receptor molecules on the surface of target cells to initiate infection. Virus-receptor binding is highly specific, and this specificity determines both the species and the cell type that can be infected by a given virus.In some well-studied cases, the virus-binding region on the receptor has been found to be unrelated to the receptor's normal cellular function.
What is it called when a substance is made up of all the same molecules?
It is an element
How would caffeine binding to an adenosine receptor affect the activity inside the neuron?
Adenosine receptors stick through the neuron membrane, so that part of them are on the inside and part is on the outside of the cell. Now, when adenosine, a natural chemical in the body, attaches to the adenosine receptor it shifts the shape of the receptor, this shift reaches all the way to the part on the inside of the cell, and causes the receptor to release attached molecules called G-proteins. These g-proteins now float around the inside of the cell and have all sorts of effects, in this case, to inhibit the neuron. Caffeine also binds to the adenosine receptor, but it doesn't activate the receptor. This means that the receptor is totally shut down, and can't work to inhibit the neuron any more. The end effect is to allow the neuron to be more active than it was before the caffeine.
Are all molecules the same size?
No, there is a huge variation in size. DNA and protein molecules are relatively huge. Water and oxygen molecules are quite small. Hydrogen is the smallest.
It takes water molecules to fill up the same space if the molecules are in the form of ice as compared to liquid water?
All molecules of water are identical, excepting isotopic effects.
What were the specialized structures in the cell membrane that are involved with communication?
cells with similar markers stick together and functions as

chemical and physical change.
Are 2 molecules in water the same?
Nope, All molecules are different. They might look the same, but they aleast have thing different.
What includes phagocytosis pinocytosis and a receptor mediated form?
Pincotyosis brings only water into the cell, but receptor-mediated endocytosis brings in other molecules as well

Which two samples of gas at STP contain the same total number of molecules?
Theoretically, if they have the same volume, all samples will contain the same number of molecules.

What is a collection of molecules that are not all the same called?
Providing the molecules are not combined in any way, then it is a MIXTURE.
What gases have in common?
All gases have same kinetic energy of molecules at same conditions.
How do you send a message to all your friends on playstation network at the same time?
You Can't Send a Message To All Your Friends At The Same Time. Just like The Xbox you have to send it one - by - one.
