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 is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
How can you sample organisms?
pit fall traps, pooters, nets
Name a technique that could be sucessfully employed to sample the organisms living in a tree?
what do you mean
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?
Kingdom Protista
If a sample is 10740 years old and has 400 atoms how many atoms are there after the organisms died?
After 10740 years, half of the sample would have decayed, so there would be 200 atoms left. If the original sample had 400 atoms, then there would be 200 atoms left in the sample after 10740 years.
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 when spreading colonies are present on a dilution plate, you would count the number of colonies on a plate with a countable amount (usually between 30-300 colonies). Then, you would multiply this count by the dilution factor used and adjust for the volume plated to calculate the total number of organisms in the original water sample. Keep in mind that any spreading colonies need to be accounted for in this calculation.
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.
How enrichment of the sewage sample accomplished?
Enrichment of a sewage sample can be accomplished by selectively culturing bacteria using specific growth media that promote the growth of certain target organisms present in the sewage. This typically involves incubating the sample under specific conditions, such as temperature, pH, and oxygen levels, to encourage the growth of the desired organisms while inhibiting the growth of others. Additionally, the addition of nutrients or supplements can help stimulate the growth of specific bacteria in the sample.
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.
How do you preserve a sample for culture and sensitivity?
To preserve a sample for culture and sensitivity testing, it should be collected aseptically in a sterile container. The sample should be kept at the appropriate temperature and delivered to the lab promptly to prevent overgrowth of contaminating organisms. It is important to follow specific guidelines provided by the laboratory for proper preservation and transportation of the sample.
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 do you use the word microscopic in a sentence?
The scientist examined the sample under a microscope and observed the microscopic organisms present.
