What is the formula to calculate size of a sample?
by using the capture-recapture method which gives you the total size of organisms in a population.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
What is a experimental sample?
An experimental sample is an experiment that is just a sample of what you are looking for.

what do you mean
If a sample is 10740 years old and has 400 atoms how many atoms are there after the organisms died?

How do you determine the number of organisms in a water sample if your dilution plate has presence of spreading colonies?
To determine the number of organisms in a water sample choose a plate that has less than 300 but more than 30 colonies. Then count the number of colonies and record the results.
Tom discovered some unicellular organism's swimming in a sample of pond water. Some of the organisms had chloroplasts but many did not. All of the organisms had a nucleus. Into what kingdom would these organisms most likely be classified?

How does carbon dating work ma?
Carbon dating works by measuring the amount of radioactive carbon-14 in a sample. Carbon-14 is present in all living organisms and decays at a known rate after death. By comparing the amount of carbon-14 remaining in a sample to the amount in living organisms, scientists can determine the sample's age.
What are biochemical oxygen demands?
BOD is the oxygen necessary for living organisms in a sample of water for the degradation of organic compounds.
What is the formula to calculate size of a sample?
by using the capture-recapture method which gives you the total size of organisms in a population.
What are the different motile organisms observed in the sample?
Wikianswers cannot answer this question without knowing what the sample was. We suggest you do not blindly copy questions from your worksheet but put some thought into it. This question requires you to have a sample, have observed it and have a knowledge of what motility is. Motile is a biological term for the ability of an organism to move freely of its own volition.
How would you thoroughly demonstrate that a particular organism is the cause of a disease?
You're not meant to have foreign organisms inside your body (excluding the gut which technically isn't inside your body). So if you're sick and the organism can be isolated and cultured from a sample you gave from the area that is affected (eg a sputum sample if you have a chest infection, a blood sample if you have septacaemia), it has to be the cause of the disease. A control sample is always given to exlude the possibility of contamintation.
What is the word that means heated until all living organisms have been killed?
Pasteurised - After Louis Pasteur, who discovered that rapid heating and cooling of a sample destroyed bacteria.
What are examples of motile?
staphylococcus,shigella
