what is usually written in the (observations(results)) section of a formal Biology Report?
in my biology manual, it says:
Observations (Results)
a)qualitative observations which are descriptive in nature and are usually written in sentences, but may be given in a chart or table.
b)quantitative observations which are measurements that are usually placed in a chart or table.
charts and tables should be titles properly (ie. Figure 1: Measured pH values of ten biological substances) and have fully labelled (including units) columns and rows……………………………
i asked my teacher ,and she said that in observations, i have to include description os substancces used.
but i dont know how to do that…please , can you help me..i beg you
…its due tomorrow…
It’s Quite Easy – you’re worrying about nothing.
All it means is that if you are writing a report about a particular BIOLOGICAL EXPERIMENT, you must include “observations” about the experiment, and also the end “results” about the experiment.
Here is an Example —
A certain laboratory conducted the following test on a certain medical procedure……..here it is below…………..
We have devised a method to extrapolate biological equilibrium levels between animal species and subsequently to humans.^Our initial premise was based on the observation that radionuclide retention is normally a function of metabolism so that direct or indirect measures could be described by a power law based on body weights of test animal species.^However, we found that such interspecies comparisons ought to be based on the coefficient of the power equation rather than on the exponential parameter.^The method is illustrated using retention data obtained from five non-ruminant species (including humans) that were fed radionuclides with different properties.^It appears that biological equilibrium level for radionuclides in man can be estimated using data from mice, rats and dogs.^The need to extrapolate low-dose effects data obtained from small animals (usually rodents) to humans is not unique to radiation dosimetry or radiation protection problems.^Therefore, researchers have reviewed some quantitative problems connected with estimating low-dose effects from other disciplines, both because of the concern about effects induced by the radionuclide moiety of a radiopharmaceutical and those of the nonradioactive component.^The possibility of extrapolating low-dose effects calculated from animal studies to humans is discussed.
In the above test, the doctors/scientists are using animals to test their ideas. The “observations’ are actually mentioned in their report, and is the following statement…..”Our initial premise was based on the observation that radionuclide retention is normally a function of metabolism so that direct or indirect measures could be described by a power law based on body weights ”
The “observation” explains what the scientists are actually testing—-that RADIONUCLIDE RETENTION IS A FUNCTION OF METABOLISM . The observation also included the scientific materials which were used and other knowledge, such as – BIOLOGICAL EFFECTS;DOSES;DRUGS;IRRADIATION;LABELLED COMPOUNDS;NUMERICAL SOLUTION;RADIATION EFFECTS
The “RESULT” would be what happened to the humans and animals that were used in the testing. And their conclusion (the results) was “that biological equilibrium level for radionuclides in man can be estimated using data from mice, rats and dogs.” In simpler terms…… rats used for testing are similar enough to humans to tell the scientists whether or not a particular treatment, or drug, will work on people. They concluded that body mass was a factor in this case .
In other types of testing, CHARTS can be used to show observations.

The Essential Difference: The Truth About The Male And Female Brain $6.98 We all appreciate that there are differences in the typical psychology of men and women. Yet underlying these subtle differences, Simon Baron-Cohen believes, there is one essential difference, and it affects everything we do: Men have a tendency to analyze and construct systems while women are inclined to empathize. With fresh evidence for these claims, Baron-Cohen explores how these sex differenc… |
