In many aspects, bacteria are more "advanced" in their_______than in their______?

Sat II Bio much? hehe\n\nI'd go for B. Bacterial metabolism can get very complex, while their genetical structure is very siple.

The study of bacteria reveals ways to prevent infections, slow them so ppl have more time, and even cure them. We could all die without it. Bacterial infections are becoming more common as time passes.

>>>If life was not created by an intelligent, self-aware,\n>>> designer, where did evolution get intelligence and self \n>>>awareness to "give" us?\n\n\nIt got it from a series of mutations and processes selecting for increased intelligence. Intelligence is simply the result of ever increasing ability to process and respond to sensory information. It is no harder to ‘get’ than size. \n\nYou might just as well ask if all organisms evolved from microscopic bacteria, where did evolution get size to give to whales. The difference between whales and bacteria in terms of size is one of degree, not kind. And in exactly the same the difference between a human and a bacterium WRT intelligence is one of degree, not kind.\n\n\n\n>>>>There appear to be three levels of life, plants (having\n>>>> no awareness), animals (having sensory perception), and \n>>>> humans(perceiving self and contemplating all things). \n\nThat quite obviously isn’t true. Anyone who has lived outside a city knows that plants perceive and respond to the passing of the seasons and the timing of the rains.\n\nOnce again I have to stress that the difference between plant intelligence and human intelligence is one of degree, not of kind. It is not the case that plants have one type of intelligence and humans have another. Plants simply have much less intelligence than humans\n\n>>>>Neoteny… How can anything retain something which it has\n>>>> not received? How can anything be received from a\n>>>> source that does not have *that* thing?\n\nI think you need to spend at leats one hour studying this subject before criticising. All animals receive the genetic instructions for their juvenile from their parents.\n\nIt is amazing that someone in the 21st century could actually believe that God personally builds young animals and that the form of a kitten has no genetic basis whatsoever.

B.\n\nOcean temperatures do not change very rapidly, and most organisms don't require large temperature changes.

You are looking at evolution incorrectly. It is not progressive and it has no direction. Your question is ill posed.

They found fossilised bacteria on mars a few years ago, while bacteria may not be intelligent combine that with the fact that the surface of mars look like it once contained water and they think that is may once have been habital. But apart from all that I don't think any scientist actually 'believe' theres any other life out there.

Humans do not dominate anything. Bacteria are way more successful than us at surviving, reproducing, colonizing and transforming every tiny corner of Earth's surface, air and water. The Earth contain more bacteria than all other organisms combined. They also fill ourselves: did you know that our bodies host more than 200 species of bacteria and that we couldn't even survive without them?

First off jamesmusik84's is completely wrong. Please don't consider any of it. The second answer is along the right path, except I have no idea what the reference to antibiotic is suggesting and some viruses have RNA genomes but many more have DNA genomes. And as far as bacteria go, both RNA and DNA are present inside there cells.\n\nSo, the answer to your question. Let's start this way: Bacteria are small single-celled organisms. Unllike eukaryotic cells (like the ones that make up animals, plants, fungi and many single-celled organisms such as yeasts) which package their genetic material (DNA) in membrane structures called nuclei, bacteria (which are also referred to as prokaryotes) don't have a nucleus. Bacteria also don't have other organelles which are found in eukaryotes, such as endoplasmic reticulum, mitochandria, chloroplasts, golgi bodies, etc. But like eukaryotes, bacteria do have an outer lipid membrane.\n\nSo, you can think of bacteria of little fluid filled sacs. Along with eukaryotic, bacteria are an example of "cells" which are the smallest unit of living things on earth.\n\nViruses, on the other hand, do not have an outer membrane. They don't the capacity to make their own proteins. They don't have the capacity ot replicate or metabolize on their own -- of which bacteria (and eukaryotes) do. It's for this reason that we don't consider viruses "living" things. Viruses have to "infect" a cell -- injecting its genetic material inside -- and use the cell's metabolic machinery to reproduce.\n\nViruses are essentially small protein "capsules" that have a piece of genetic information packaged inside. Because viruses are required to infect a cell to propogate themselves, they are classified as obligate intra-cellular pathogens.\n\nViruses tend to only infect specific cell types. Some infect bacteria. Some infect plants. Others infect animals. The specificity of what a virus can infect is goes beyond whether they can infect bacteria, plants or animals. Usually viruses have to infect a very specific animal, plant or bacteria. And even in the case of viruses that infect animals and plants, not only do the infect specif animals, they are usually limited to a few cell types whithin that animal.\n\nTake HIV for example: to the best of my knowledge HIV only infects humans (i.e. the "H" in HIV -- Human Immunodeficiency Virus). But it doesn't just infect any human cell. HIV only infects white blood cells -- specifically a class of white blood cells called T cells (there are many other "classes" of white blood cells including such things as B cells, NK cells, neutrophils, basophils, eosinophils and macrophages).\n\nI hope this sheds some light on the matter.

yup Bacteria it was.. See we've earned the right to live on this planet cause we were able to survive against the bacterias, we've build himune system against them buggers but it took us THOUSANDS OF YEARS to accomplish that!! Those tripod didn't think of it when they planed to attack the planet. Earth is all about survival of the fittest baby!!! VIVE LES MICROBES!

animal cells are smaller and more numrous

In my opinion, things are just way to complex for general evolution. I could see maybe a large colony of mold somehow coming into being on it's own,, but all the complexity we have here., No chance.

Maybe prokaryotes. But I'm not sure... I think there's still a debate about them cause they're not really living creatures... They are "alive" when they are inside a host, but otherwise, they're just lifeless proteins.. :)

=at his stage of the game you would think we would be more advanced.  That is questionable in my mind at this time.  Remember Apes and Orangutans are pretty close to us as far as DNA is concerned.  What a shame we cannot live peacefully together.  These in control with the power make all of the decisions about our good men and women lose their lives over their decision while they are safe and protected.

It can be either (a) or (b) or (d). This depends on how the strong the cell is or how conducive is that cell for that virus. (e) is not possible because virus and bacteria are two different organisms. Virus is much more smaller than bacteria.

many people with advanced education think that people in areas like new guinea are smarter and more intelligent then most white people in the world, and that they are more intelligent overall\n\nim reading currently the book guns germs and steel by jarod diamond

In my own observation, all micro organisms puzzle the modern biologists, especially the inexplicable origin of the life force behind the protoplasm in the living nucleus.  All that they have done so far is to name and describe the composition (oxygen, hydrogen, carbon, nitrogen, calcium, magnesium, sulfur, potassium, etc.) and the observable phenomena surrounding the cell.  \n\nOn the othe hand, it is also possible that biologists understand this already, they are just trying to find the right time and the right words to make us understand.  As the saying goes: "The teacher will appear when the student is ready."

There are more described species of insects at present, but it's unlikely that this is representative of the actual diversity of the organisms.\n\nInsects are easier to distinguish using visible characters, and there's more economic impact of various insect species, so there's more incentive to work on them.  \n\nWhile there may be millions of different species of bacteria, they are harder to distinguish from each other, except possibly by comparing genetic material.  So no one has actually done the work necessary to categorize all of those species yet.
