The Bacteria.

[FearGod]

Bacteria is feeding on the remains of the food causing the dental plaque to form.

We can see them.

Not by the naked eye.

 

[FearGod]

You read and responded to them earlier in the thread: GO BACK AND RE-READ THEM FOR YOURSELF.

I'm done with your trolling game.

Just tell me in which post you replied my question, is it hard to do that?
In explaining how the bacteria can resist? in which mechanism?

 

[FearGod]

Life has developed in various environments. In arctic colds, hot deserts, deep seas, undersea volcano vents, etc. This is adaptation and evolution. Read this: http://voices.nationalgeographic.com/2013/08/02/5-extreme-life-forms-that-live-on-the-edge/
People like Fear God are soul of these threads. Interesting to see regression of knowledge, especially among Muslims.

I'm discussing actually the bacteria according to science, i didn't discuss Islam here.
It's discussing your origin, the bacteria according to science.

Should heating all kinds of bacteria at the boiling degree turn it to the gaseous state?

Just as humans are not a single state of matter neither are bacteria. Bacteria have its solid and its liquid portions. At its base functions it isn't done in a state of matter at all but on the molecular level. You can boil bacteria to a certain point where it should kill it. The solid bits will remain but its possible to dehydrate cells. There are some cells that have adapted at extremely high temperatures so that temperature will be far higher than normal bacteria. Your average bacteria found on household objects will die in boiling water though. This is one of the reasons why it is recommended as a form of sanitizing.

I don't know...is it hard to read and comprehend an answer when it first comes up? You responded to the posts, but obviously didn't read or understand them if you can't look back and find them now.

But let's see, you finally got around to asking something like "how can bacteria survive extreme temperatures" in your post #17. In post #23, I provided an explanation. In post #75 you finally formulated your question as to specifically why bacteria can survive where humans can't. Others provided other versions of explanation, and/or links, in other posts.

The question remains: so what if (some) bacteria can survive under conditions under which humans will die? Biologists understand how and why bacteria can do this and humans can't. What is your point?

Yep. That is in fact the definition of solid.

The bacteria has a simple delicate structure while resisting a harsh conditions, i think you realize
that burning a paper isn't like burning a plastic and not like burning an iron.

You aren't giving me an explanation of why that simple structure can bear the hard conditions?

 

[FearGod]

Yep. That is in fact the definition of solid.

Where can we see it in a bacteria?

 

[Jumi]

Not by the naked eye.

I don't know why it matters, but yes, we can see some of the largest bacteria with naked eye:

Epulopiscium

is one of the largest known bacteria, a million times bigger than Escherichia coli or Bacillus subtilis. It is large enough to be seen with the naked eye at 600 µm.

Cells of Thiomargarita namibiensis are large enough to be visible to the naked eye. Although the species holds the record for the most massive bacterium, Epulopiscium fishelsoni – previously discovered in the gut of surgeonfish – grows slightly longer, but narrower.

Like your skull, your bones. They are solids. Your skin also is solid but has different properties, it is pliable. Etc. What does solid mean to you? I hope it is not different. One never knows.

 

[Parsimony]

If you heat any bacteria up enough, it will die. One of the reasons that some bacteria can survive higher temperatures than humans is because their enzymes are capable of functioning at higher temperatures without denaturing (i.e. losing functional structure).

 

[FearGod]

I don't know why it matters, but yes, we can see some of the largest bacteria with naked eye:

We were talking about the dental plaque as a collection of large numbers of bacteria, but the plaque
isn't the body for such collections and we can only see the bacteria by the microscope.

Regarding a bigger evolved size of bacteria, i don't have anything to discuss about it,
actually huge animals including humans were that unseen bacteria, so what strange
for finding a bigger bacteria?

 

[Aupmanyav]

Where can we see it in a bacteria?

Under a microscope. The cell wall and the flagelles are solid, something like our skin and hair, only many more times dainty.

Wikipedia and Google are short-cuts to knowledge. Make it a habit to check things there.

"In the oral cavity, there are different types of bacteria that normally present in the mouth. These bacteria and leukocytes, neutrophils, macrophages, and lymphocytes are part of the normal oral cavity and contribute to the individual's health. Approximately 80–90% of the weight of plaque is water. While 70% of the dry weight is bacteria, the remaining 30% consists of polysaccharides and glycoproteins. Streptococcus mutans and anaerobes are the initial colonisers of the tooth surface, and play a major role in the establishment of the early biofilm community."

Where can we see it in a bacteria?

In the membranes and especially some of the more sturdy sections such as the flagellum. Though I suppose its up for debate on if its actually a solid or not. Parts of it are definitely not liquids. Part of this is because of the lipid bi-layer that makes up the main membranes which are composed of disaccharides and amino acids forming together in a structure. At this point its harder to tell if its a liquid or a solid because it functions as a solid but behaves as a fluid. The reasons being because in cell wall and other structures other forces other than base matter are at work.

What was the point of this btw? They are clearly not a simple liquid as they have structure. No liquid has self sustaining structure.

You are trolling. You did not ask this: Ask a question and stick to it; changing your question six or eight times in a thread and heading off on tangents and changing the subject is trolling.

You don't have a case: you keep asking for people to explain to you what has already been explained. Since when are bacteria "delicate structures?" They are certainly "simple," compared to many other organisms, but delicate? Bacteria are often described as "hardy," but I don't recall ever seeing them described as "delicate." Please cite your source.

While simpler in structure than the cells in humans, the same basic principles apply--except that simpler can also be more durable. SOME bacteria have the ability to enter a state of suspended animation when conditions change from those in which they thrive--even so, those few that enter suspended animation can still be killed by extending the duration of the exposure, or changing it (heat plus acidity, for example, is more effective than either alone. The cells of humans and other multicellular creatures have more trouble adapting to such conditions because their cells are more complex than bacterial cells.

Now then, there are a wide variety of bacteria that live in extreme conditions: high temperature, high or low acidity, etc. Structurally, they are very similar to those who live under less strenuous conditions. The difference? They have evolved to live under those conditions. And you know what? When the conditions they're in start to get out of their comfort range, they, too, can enter a state of suspended animation until they get into conditions that are favorable again.

Now then, I am not a bacteriologist or biochemist, so I can't explain the details to you, but be assured, if you would just read up a little on this, you would understand that biologists DO INDEED understand what is going on with bacteria, and how they can survive in conditions that will kill humans or other multicellular creatures. IT IS NOT A MYSTERY to science. And if you don't believe me and the others posting in this thread, then GET AN EDUCATION for yourself.

Why is it important to you that they can't be seen without technology available since 1660s and 1670s?

Regarding a bigger evolved size of bacteria, i don't have anything to discuss about it,
actually huge animals including humans were that unseen bacteria, so what strange
for finding a bigger bacteria?

Shouldn't you know the reason why you were asking for bacteria we can see?

 

[LuisDantas]

We know the reasons for how the bears save their energy but do we know how the bacteria resists the extremely harsh conditions?

Strictly speaking, we know how bears developed that adaptation. It is not like it was a conscious choice by anyone.

Hi, Aupmanyav. There was some sort of syntax trouble with this picture, so I took the liberty of hiding the code with spoiler tags and annexing the image here. I hope you don't mind.

A bacteria - a virus - not alive at all...it may be an ANIMATED FORM - but it is not truly ALIVE....To my mind, to be TRULY alive - the INDIVIDUAL must be capable of realising their OWN existance....Certainly, for a form such as a bacteria or mircobe this cannot apply - and even for much MUCH more complex forms,this status of truly alive does not apply either...

Most insects for example are NOT truly alive either - they are animated forms that act purely on PROGRAMMED INSTINCT - they are automotons - robots..Even some larger animals,higher forms we may think, but animlas such as cows and sheep - likewise, not TRULY alive - still largely instinctual and none sentient...

Indeed, thinking about it, I find crucial criteria arise that I personally would use to define TRUE life - the form MUST be sufficiently SELF AWARE - posess a SENTIENT mind - and preferably, have a good EMOTIONAL capacity as well.....Certainly if the animal does not even realise that it IS alive, if it is purely instinctual and following genetic imperatives only then that is not really being alive at all - so a SENTIENT Self aware mind is a definate pre requisite to TRUE life..

Once the animal form develops BOTH Sentient mind AND sufficient EMOTIONAL capacity -then it begins the real journey as it is now capable of sustaining it Self as an ETERNAL SOUL..

Really - life - existance - is NOT about form, structure, physical conditions - not at all - TRUE LIFE - is all about MIND - becoming fully SELF AWARE - attaining SELF GNOSIS...The form is IRRELEVANT - eventually every mind will reach and disclose its own full potential - for we all exist as a unique form within a SINGLE fully omniscient MIND that caused it all to unfold..There is no seperation at all - only the ILLUSION of a physical form that the mind currently inhabits and identifies it Self with...I and My Father are ONE - always - life is a journey of Self discovery - existance here is a progression of stages of Self realisation that takes us right back to this Divine Source of it all...For a Human Being - life here is a journey of Self REMEMBERING - Whoa nd What we are BEFORE we took these illusionary forms..For those with ears to hear.......

Congratulations. According to your "logic" Earth is a barren planet with a single form of life, us.

Bacteria can survive high temperatures, humans will turn into ashes, if not strange then can
you explain how this to be simple?

Tardigrades can survive the vacuum of outer space(among other things that would kill us). Are they Angels of Allah?
