Most motile bacteria move by means of flagella, if present. Motile means that they are capable of motion. Flagella is the plural of flagellum.

What are the bad things that are not allowed into a cell?
In an animal cell, the plasma membrane keeps out unwanted objects. In a plant cell, the cell wall does this. Unwanted items would be any foreign unknown object, harmful bacteria, or wastes excreted by other cells. Cells only let in certain things, and they do this through selective permeability. They let in water and sugars and nutrients and other things that the cell requires. They can tell what to let in because proteins attached to the plasma membrane act as signalling devices, telling the plasma membrane whether or not to let something in. Some bacteria trick the plasma membrane into letting them in.
Can you do a gram stain from 3 day old nutrient agar plate or should i do anohter t streak and let it grow for one day nd then do gram stain?
there should be no problem with doing a gram stain on a 3 days old bacteria strain unless your working with spore making bacteria, then you would need to do another streak, unless your familiar with spore stain methods but you should keep the bacteria cold at 4 degrees if you dont want them to die.
When you join two glucose molecules you get maltose what is the molecular structure of maltose?
The actual diagrams of the molecules in helix and pleated forms can be found on Wikipedia by searching Maltose. This site would not let me import the pics. sorry
Does anyone have the worksheet called the dodgy barbecue?
Basically, the answers are this; 1) Bacteria can enter the body through a cut OR IN THIS CASE through food poisining, which happens when you don't cook meat properly; cooking it kills the bacteria, and because hamburgers are processed, the inside has been outside at some point (if that makes sense?) so there could be bacteria anywhere in it. 2) The bacteria must overcome both the primary and secondary responces; Primary being stomach acid, secondary being white blood cells. (Antibodies, see Q. 4) 3) The bacteria split (it's called binary fission), they copy their DNA into a new cell. It's like they're cloning themselves :) 4) The white blood cells produce antibodies, which cling to the bacteria and eventually kill it. The first time you have food poising it takes a while for the white blood cells to produce the antibodies because they have to recognise the food poising as bad. 5) The body can now recognise the bacteria, plus the antibodies have been produced, so will probably hang around for quite a while. So next time the same kind of bacteria arrives, either the already present antibodies will attack the bacteria or the white blood cells will make some antibodies super fast. To get level 7: -The guests got food poisoning because there was bacteria on the hamburgers and because they weren't cooked properly, the heat didn't kill the bacteria, so it entered the body. -Cells called white blood cells help stop bacteria entering the body by producing antibodies. -Draw a diagram of a cell splitting in 2 to make 2 cells like the one you started with. -The body responds to the infection by producing antibodies which cling to the bacteria until they kill it. Plus it either gets rid of it via throwing up (ew.) or digests it real quick so you get diarrhoea (also ew.) -If the body was infected by the same type of bacteria again it would deal with it quicker because it could produce antibodies super fast because it recognises the bacteria. -It doesn't actually tell us how much bacteria the guests consumed so let's say, like, 4. It DOES tell us that each bacterium divides every 20 minutes. So in 20 minutes there's 8 bacteria. In 40 there's 16. In 60 there's 32. And so on. Thing is, we don't know when the antibodies kick in. Express this in numerical crap. -Human cells are about 10 times bigger than bacteria cells.
What structures let bacteria be motile?
Flagella and cilia because this is how prokaryotes move around.
Which bacteria are present in the small intestine that help in digestion in humans?
Well, let me put this short and sweet: If there were no bacteria in your digestive tract, you wouldn't be able to digest much anything.

Are animals from the class lamprey motile?
Lampreys aren´t a class, they´re a separate species. But yes, they are motile, they swim freely - that is, until they attach themselves to a fish host with their mouths and start scraping off flesh with their tongue. But they can let go and swim away whenever they want.
Can you get a fever by getting stuck in a life sized freezer?
The chemical molecules in the freezers molecular structure slowly seep though the gaps in a human ears/nose/mouth let in the bacteria used to kill cells and bacteria in food called Actinobacillus Actinomycetemcomitans which can give you very bad diseases
What is the present participle of let?

How to not let the past kill your present and future?

Can an apple be affected by bacteria?
You need moist and warmth and let it rot and surely the bacteria will start to grow within 2~3 days.
