just to know, who should be able to adopt children?

I think everyone who has everything necessary to adopt a child

Suppose you placed a plant that contained starch in the dark and left it there for about a week what would happen, if you test it for starch?

These are some questions from my study guide. I know some of them but if i can get a better understanding on them would be great and would help me pass the test. I have got all A's no test and quizzes in my Government class but this test that is coming up kinda worries me. So if you can help it would be awesome.

What are the goals of the Federal Reserve?

What are the three monetary tools of the Federal Reserve?

What does the Federal Reserve attempt to achieve with each monetary tools?

What demographic statistics have become increasingly more important to the long range viability of the social security system?

What is the main tenet of NATO with respect to the interdependence of this organization’s members?

Who is harmed by inflation? Who gains from inflation?

Why do nations implement tariffs?

What is the goal of free trade?

Why do nations agree to treaties?

Question

Can you change the rate of a chemical reaction by changing the size of the particle?

Hypothesis

If I Alka-Seltzer, a tablet, that when comes in contact with water, releases carbon dioxide gas, then I can use different masses of Alka-Seltzer and the carbon dioxide gas released from the different masses of Alka-Seltzer to tell whether the particle size affects the rate of a reaction. Because the main ingredients in Alka-Seltzer are Aspirin, citric acid, and sodium bicarbonate. When Sodium Bicarbonate

dissolves in water, it dissociates into sodium and bicarbonate ions. The Bicarbonate reacts with hydrogen ions form the critic acid to from carbon dioxide and water. The carbon dioxide released from the different masses will allow me to tell the rate of reaction.

Thanks this if for a science project......tell me whats wrong please...

thanks

"The Electoral College is shameful. How can a candidate who receives more votes for the presidency than his competitors(s) lose the election? We need a new method to choose our president.

Do you agree or this agree. Explain

Using any materials you have at your disposal, create a 3D Cell Membrane model illustrating one of the 6 types of cellular transport: Diffusion, Facilitated Diffusion. Osmosis, endocytosis, exocytosis, sodium/potassium pump. This 3D illustration should actually display cellualr transport. You must use your imagination and creativity to ensure success with this activity.

This is what my teacher give to me.. Please help me come up with some ideas...............

i emailed her some ideas but she turned them down.

What are some good science projects to do?????????/

If you look at a plastic bag (ziploc) under a microscope will you see holes in it. I am doing an experiment and i would be boiling the bag in water I just want to know if the condensation will enter the ziploc. And if the chemicals that i mix in hthe solution outside of the ziploc will it also enter.

Thanks

i have a question, is there a equation for the lipid bilayer in the membrane of the cell.................like for glucose the equation is C6H12O6

and who were the 2 people who discovered the cell membrane.

Thanks if you know and thanks if you don't know.

By the way this is not home work I just want to know what i is. I am studying for a test on monday.

which one do you want?

and tell me why........

I am undecided so persuade me people.

Can anyone help me with the problem bellow.

1 Explain passive transport across the membrane by simple diffusion and facilitated diffusion.

2.Explain the role of proteins pumps and ATP in the active transport across the membrane

3.Explain how vesicles are used to transport materials within the cell between the rough ER, golgi body and plasma membrane

4. Describe how the fluidity of the membrane allows it to change shape, break and re-form during endocytosis and exocytosis

If anyone could help thanks.

I need help with this, can you breakdown these meanings for me....

isotonic is a solution where the solute concentration of the solution that the cells is in is lower than the solute concentration of the cell's cytoplasm

Thanks so much

Hypertonic

is a Solution where the solute is concentration of the solution that the cell is in is higher than the solute concentration of the cell's cytoplasm

Hypotonic

is a solution where the solute concentration of the solution that the cell is in is lower than the solute concentration of the cell's cytoplasm.

Can anyone explain the works, the in and outs of cellular transport, any information will be grate any web sites will be even better. thank you for your helpppppppppppppppppp.
