Q. Also is true that all types of bacteria cannot see ? If all types of bacteria cannot see how do they sense the world smell or chemicals?
The bacteria have no light rods or cones?
The bacteria have no light rods or cones?
A. Bacteria are smaller than most eukaryotic cells, such as body cells. Viruses are so small they can infect bacteria.
Not bacteria can see. Some Protista have light sensitive patches to guide them to food, but they can't "see". Bacteria instead float around. They use chemicals to communicate with the world around them.

What important roles do bacteria play in the deep ocean? What would happen if they werenʼt there?
Q. What important roles do bacteria play in the deep ocean? What would happen if
they werenʼt there?
they werenʼt there?
A. Bacteria serve to rid the ocean floor of dead organisms by decomposing them. If they weren't there, the ocean floor would accumulate too much biomass.
How long does it take for good bacteria to form in a fish tank.And does the good bacteria break down the poop.?
Q. Its self.I know that the good bacteria feeds on ammonia but does it break down the poop it self.And how long does it take the good bacteria to form in the plastic case of the filter.I hear the term the filter media what does that mean.And how long can i go before i have to clean it.
A. Pooh will rot away causing amonia.. good bacteria will then eat the amonia converting it into nitrite..
A differnt type of bacteria needs to form eating the nitrite turning it into nitrate...
Nitrate is removed from he tank by frequent water changes (live plants and algae will also eat the nitrate)
The colonies of bacterias can take up to 6 months to form.. they form in the filter, gravel, and on any ornaments.. So it is best to only add a couple of hardy fish (zebra danios) for this period or read up on a fishless cycle..
Filter Media - is the sponglike inserts you put into a filter. There are variations on this depending on your filter.. After the intial 6 month period described above it is best to rinse the media in old tank water to maintain bacteria colony.. do this monthly..
And if it too blocked and need replacing only ever change half of the media at a time and ensure you rinse in old tank water
You use tank water you have poured into a seperate container because the chlorine is too high in our tap water and this will kill the fish.

What temperature is good bacteria killed?
Q. I always hear bad bacteria is killed at 145 degrees for a certain amount of time, but what about good bacteria. Is it killed in the same range or at higher temperatures? I hear that low temperature pasterization of milk kills off the bad bacteria and preserves some of the good bacteria and it's heated at 145 degrees for 30 minutes. Is this true or are they giving false statements to sell this milk?
A. Unless the bacterium has an endospore which is resistant to heat and chemicals, the thermal death time is the same for most species of bacteria, good or bad. Pasteurization of milk is intended to kill pathogenic bacteria typically found in milk. The standards for the quality of milk is set by state and federal agencies. Those bacteria found in pasteurized milk are considered thermoduric (tolerate the pasteurization temperature) and psychrophilic (can grow at refrigeration temperatures) and will eventually cause the milk to spoil. With ultra-pasteurization, milk does not have to be refrigerated.
