I presented with a RBC of 5.70, a hemoglobin of 15.7, and a hemacrotit of 46.4. What kinds of tests will the hematologist do? I'm worried about being anesthesiized for anything becaue I have a great fear of being put out.

Also, the blood tests done by the lab included a protein electropohoresis, and these were the results:
Total - 7.3
Albumin - 4.3
Alpha-1 - 0.3
Alpha-2 - 0.8
Beta - 0.9
Gamma - 1.1
A/G Ratio - 1.4

Do any of these values indicate cancer?

There are some who look at this from the scientific view and say Big Bang. Others will say God created all. But if you look into it hard enough it starts to boggle your mind a little. Sometimes i think if God created all then what created God? Did He just appear one day in a huge empty space? If so then what created that space? Do you see what I am getting at? This goes for the big bang as well. People say that it was created by gases and dust all collecting together and exploding. But then what created these gases and dust? If they were created by different molecules and such then what created these molecules? Is it and infinite chain of creation? If so then was there ever a beginning? Sorry if this is a bit confusing but im sure some people will understand. TY

I know that we can't survive in a vacuum because we need the pressure of the atmosphere to survive. But what happens to us in space? How long could an astronaut survive outside the shuttle with no space suit?

a) The shape and function of a protein is determined only by the different types of amino acids that make up the chain.
The order they appear in is not a factor

b) The sequence of amino acids that make up a protein are known as the primary structure of the protein

c) Although proteins are long and complex, they have a regular structure that results from hydrogen bondng

d) The tertiary structure of a single protein molecule is created by hydrogen bonds between an amine group and a lone pair of electrons on an oxygen molecule

e) One type of secondary structure found in proteins is α-helix

f) The structrure of a protein that results from only hydrogen bonding between the side chains of the different amino acids is called the tertiary structure


I have tried everything and nothing seems to be working : (

She has a house that she knows the history of, including knowing about a man who used to live there. When she mows the lawn in the backyard she says she can see him standing in the back window watching her. But when she turns her head, he's gone. If there were really a spirit, wouldn't he still be there when she turns her head?

I will admit, some things that happen in that house are a bit difficult (but not impossible) to explain. Like my son's talking dog toy would randomly say phrases in the middle of the night even though no one is near it to push and buttons, that sort of thing. As well as what I can only describe as a feeling of unease when I'm alone in the kitchen at night.

I'm attempting to create as realistic of a weather system as possible for a game I'm making. Unfortunately, I lack a basic understanding of how weather works, where it starts, what does what, etc. If anybody has a site that explains weather in terms a child can understand, and then builds upon that knowledge, that would be simply fantastic!

I wish I had more knowledge to ask a better question, but I'm completely oblivious to how weather works. An explanation of how realistic weather can be created in a game would be great too.

Thanks!

Ok, ill type it out how it is with the information I got from it. It's obsurd how teachers can give such a complex question at the Physics 11 level!

Tim tries to crush a 0.58kg basketball but is only able to compress it by 1.5cm when a force of 50N is applied.

a) Spring constant?
b) When he throws it against the floor it is compressed 3.4cm. How high will it bounce?

I got Force.. which is F=kx F = (3333.33N/m)(0.034m) thus F=113.33322N
I got accel.. which is F=ma A = 113.33322N / 0.58Kg thus A = 195.402m/s2

Now without using anything that has to deal with energy and simple harmonic motion.. I have to somehow get how high the ball bounces with Kinematics.. but I know Vf = 0 of the ball but not Vo.. hmmm help me out people around the world! Thankyou

Love, Michael.
