Biology - October 2006

Here is a very possible scenario:

Human population continues to grow exponentially. Eventually, resources are depleted, pollution is rampant, and the population will suffer a steep crash as is the case in laboratory population tests using bacteria in petri dishes etc. Perhaps even nuclear wars over resources etc.

End result: Oceans are virtually lifeless, hardly any trees, pollution covers entire earth, no wildlife, no humans..

The only animals that seem to posses the resiliance to survive in such environments are primarily rats and bugs/roaches.

Here is the question:

Considering what we know about genetics, in terms of evolution, and biology, would planet earth (assuming there are no more humans) recover and again produce the variety of wildlife and plant species it once had?

Also considering that there would be a massive population of rats and roaches, would newly evolved species even stand a chance against these resiliant animals? Or would they be immediately killed off?

Is it simply because they are afriad to open a science book or read about biology and mutations, dna, and survival of the fittest, or is the believe of a superior being too much for some to deny.....even though there is zero evidence for it.

1- Why is fermentation important for yeast?

2- Which process DOESN'T completely break down carbs? Fermentation or respiration? How does this affect the amount of ATP released?

3- Why would a patient die from having distilled water administered intravenously (it goes directly into the bloodstream)?

4- How does the process of preserving meat (how it can be stored for months w/o refrigeration) by covering it with salt & spices work?
--------------------------------
1- I have no idea & I can't find it anywhere.

2-- I think its fermentation, and I think that as a result less ATP will be released..but idk if that makes sense.

3- I know it has something to do with the red blood cells, I think that they burst because of the hypotonic environment..

4- I think it has to do with the hypertonic environment created by the salt & spices..but I don't understand the details or anything beyond that in regard to the preventing the meat from spoiling.

Please Help me! Thank You!

Hippopotami, despite their heavy weight, are not tall animals. In the wild, there are often well enought concealed by vegetation to remain unseen until one is within very close proximity of the creature. Hippos are highly territiorial and can outrun and out-distance all but the fastest of human athletes. In the event of a hippo attack, unless one is very close to sturdy shelter, the best hope for survival is to successfully kill the animal. This is for a research project and is an entirely academic exercise. Thanks in advance for your help.

we have killed off other homo's or evolved from other homo's, for example erectus, Homo neanderthalensis, and Homo floresiensis just to name a few. Also a species is ultimately defined as having the ability to only fornicate with orginisms of the same species.....so my question is can't there be a very old tribe of people that have only mated with each other for thousands of years and can't reproduce with other homo sapiens...making them another human species? i said this in my evolution class and everyone including the teacher mocked me
