How to determine if an amoeba is alive?

You kill it by breaking it open. When it stops moving you know it's dead. One amoeba? When you look at a sample there's usually alot of them, how did that happen? Amoeba's are always slivering.

How is the slow moving Amoeba able to capture a protozoan or other rapidly moving organisms?

It sits and waits in ambush and then--> wham! bang ! pow ! < that little slow moving amoeba hits that organism over the head when it's least expecting it.

Explain the difference in size between Plasmodium and Amoeba by comparing their lifestyles?

They are asking about how their lifestyle (what they eat, where they live) effects their size. If you look up Amoeba and Plasmodium in Wikipedia you will fast see that Ameoba engulf their prey and Plasmodium such as malaria act as parasites living within a cell of the host. It should be simple to explain why these differences would necessitate a difference in size. Hope that helps.

A Sporozoan has a different life cycle then an Amoeba. What is the major difference in life cycles?

Sporozoans form spores in which they can hibernate. Amoebas do not form spores.

How do Paramecium or Amoeba digest there food?

They engulf food particle by phagocytosis. The food vacuoles fuse with lysosomes, and the enzymes digest the food. Undigested material is later remove by exocytosis.

What characteristics would you associate with an amoeba?


What is the official name for amoeba infection? Can you give me some links on information on amoeba infection?


what are the signs of amoeba? does the local park lakes test for it everyday?

Amoeba can be found in many places,I doubt whether they would test waterways etc unless an actual outbreak of illness occured nearby.Read this link article,it will give you details,but get your son off to the doctor to be sure.

How does the Amoeba use its pshyical features to live in its particular habitat and life style?

Amoebas do indeed live in different aquatic habitats. Its main adaptation is called a contractile vacuole. This organelle allows the amoeba to "pump" in or out water, depending on its needs. If the amoeba is placed in an isotonic solution, or the concentration of solute outside is the same as the amoeba, then nothing will happen. When placed into a hypertonic solution, say, saltwater, then water will rush into the amoeba and it will pump water out using the contractile vacuole.


If p is the probability that a single amoeba's descendants will die out eventually, the probability that N amoebas' descendants will all die out eventually must be p^N, since each amoeba is independent of every other amoeba. Also, the probability that a single amoeba's descendants will die out must be independent of time when averaged over all the possibilities. At t=0, the probability is p, at t=1 the probability is 0.25(p^0+p^1+p^2+p^3), and these probabilities must be equal. Extinction probability p is a root of f(p)=p. In this case, p = sqrt(2)-1. The generating function for the sequence P(n,i), which gives the probability of i amoebas after n minutes, is f^n(x), where f^n(x) == f^(n-1) ( f(x) ), f^0(x) == x . That is, f^n is the nth composition of f with itself. Then f^n(0) gives the probability of 0 amoebas after n minutes, since f^n(0) = P(n,0). We then note that: f^(n+1)(x) = ( 1 + f^n(x) + (f^n(x))^2 + (f^n(x))^3 )/4 so that if f^(n+1)(0) -> f^n(0) we can solve the equation. The generating function also gives an expression for the expectation value of the number of amoebas after n minutes. This is d/dx(f^n(x)) evaluated at x=1. Using the chain rule we get f'(f^(n-1)(x))*d/dx(f^(n-1)(x)) and since f'(1) = 1.5 and f(1) = 1, we see that the result is just 1.5^n, as might be expected.
