Q: Why does a test tube contains albumin and pepsin?
A: Because it would rather contain that than be trypsin out on cokein.
Incidentally, if a test tube contained an albumin of some sort (as albumins are a vast group of different proteins) and a proteolytic enzyme such as pepsin, the albumin would not have much time to come to terms with its identity as an albumin before it would have to come to terms with not being an albumin anymore.
So I believe your question would be "Why DID the test tube contain albumin and pepsin", which sounds like a setup for a great biology joke - be sure to contact us once you figure out a punchline!
Q: How would you summarize this article? 3-4 sentences. USE UR OWN WORDS!
A: Bored Australian Scientists are bored, they'll make ANYTHING glow these days, GFP variants are amazing, and UR is not a god damn word.
Yup. That about sums it up.
Q: If you compare two protists of equal volume, which would have a higher surface-area-to-volume ratio?
Spherical or Cylindrical?
A: It's more a question of geometry than of biology, isn't it? Nevermind the fact that they generally seem to have more complex forms than just circles or spheres...
And here we thought the time for nonviolent protists was over.
Q: What would happen to a cell if its plasma membrane lost its selective permeability?
I only have one more question to this stupid assignment and i cant find it anywhere in my book. can someone help me with the question above?
A: Simply put, the cell would be [EFF!]ed up beyond all recognition.
There are two ways that a membrane may lose its selective permeability - either becoming completely permeable or not permeable at all.
Let's put this very simply. Let us say that the cell is a house, its assorted organelles and products are the residents, and the cell membrane is its brick walls. It has doors, it has windows, and it has a particularly irate T-cell that fancies itself a guard dog. Its name is fluffykins.
Suppose we take scenario one. The membrane is not permeable at all. Basically we just bricked these poor bastards in the house and boarded over their windows. Family can't go to work, meaning no food, meaning that sooner or later they're going to go crazy and cannibalize each other. You know, sorta like on Big Brother, except it's not on the air.
Point of the matter is, everybody dies.
Now let's take scenario two. We rip the doors and windows open, and, you know what? Just for fun, we rip the damn walls open too and replace them with lovely decorative cardboard. You know, like they build houses in those Earthquake Prone Areas in China.
Now everyone's free to do what they do, Except that anything and anyone can come in. In excess. Think of it as a huge shopping spree, except, it's a shopping spree of [i]doom[/i]. Sooner or later, Important household gadgets suddenly disappear because they decided that the ratio of gadgets in the house to the gadgets outside the house is unequal and there must be balance. And every little drop of rain leaks in until the entire place floods up and explodes. In the extra-cellular space.
Of course, this is a highly simplified explanation, but we believe that if you have at least two and a half working neurons, you could come up with a way to make this sound biological enough for your assignment. The reason it isn't in your book is because, really, when you think of it this way, it's blindingly obvious. ^^
