We hypothesized that the beavers in this study will choose trees that are small in circumference and closest to the water.
Without these results, the experiment would have been useless.
In order to maximize energy, beavers will choose trees that are closest to their central place the water and require the least retrieval cost. More particularly, focus your discussion with strategies like these: What did you find out.
Although this may seem as though it is a short length to contain all of the required information, it is necessary because it forces you to be accurate and yet compact, two essential qualities. The four remaining samples contained Catecholase ranging from 0.
Did it remain constant or was it a variable as well.
Since the energy yield of tree species may vary significantly, we also hypothesized that beavers will show a preference for some species of trees over others regardless of circumference size or distance from the central area. Other studies suggested that beavers avoid trees that have chemical defenses that make the tree unpalatable to beavers Muller-Schawarze et al.
Conclusion In this lab I learned about the structure and function of the smallest eukaryotic organisms, the unicellular protists. The samples with the highest enzyme concentration had the greatest absorption rate of 95 percent compared to the sample with the lowest concentration and an absorption rate of 24 percent.
Instead of saying that the absorption rate was high, specify how high in comparison to samples with low absorption rates. The light wavelength used in the spectrophotometer was also specified telling the reader that wavelength was not one of the variables manipulated in the experiment.
This suggests that a higher concentration of enzymes leads to a greater product production rate. Italicized words are links to explanations describing why the sentences are a good or bad example of an abstract.
Their organelles are a mixture of animal and plant structures, but they all have nuclei, a feature which distinguishes Protists from other unicellular organisms. The purpose of this experiment was to identify the specific element in a metal powder sample by determining its crystal structure and atomic radius.
What is the significance of the results.
We compared the absorbance rates in samples with varying enzyme concentrations and a constant pH of 7, and with samples with constant enzyme concentration and varying pH levels.
Results Overall, beavers showed a preference for certain species of trees, and their preference was based on distance from the central place.
The best way to attempt to go about writing an abstract is to divide it into the sections mentioned above. The samples with a pH between six and eight had the greatest absorption rate of 70 percent compared to an absorption rate of 15 percent with a pH of 4; this suggests that Catecholase is most effective in a neutral pH ranging from six to eight.
The main objective of this lab was to determine beaver Castor canadensis food selection based on tree species, size, and distance. The experiment is already finished. The amounts of enzyme do not need to be stated, nor do the pH levels.
The optimal foraging theory assumes that animals feed in a way that maximizes their net rate of energy intake per unit time Pyke et al.
This finding agrees with our hypothesis that beavers are likely to show a preference for certain tree species. Discussion Although beavers are described as generalized herbivores, the finding in this study related to species selection suggests that beavers are selective in their food choice.
Also, due to the large number of students taking samples in the field, there may have been errors which may have affected the accuracy and precision of our measurements.
The author states that different samples of enzymes were tested, but mentions nothing about the contents of the samples.

Examination of Protozoan Cultures to Determine Cellular Structure and Motion Pattern Abstract.
Protozoans are unicellular eukaryotes with either plant- or animal-like characteristics. Through careful observation, we analyzed various protozoan cultures in order to identify characteristics associated with cell.
Talk your plan over with your lab adviser (PI, post doc, etc.) before you start writing. Your abstract must be YOUR words, not from someone else in your lab or another lab. It is great to read abstracts written by others, but put them away before you write your own.
The Abstract summarizes four essential aspects of the report: the purpose of the experiment (sometimes expressed as the purpose of the report), key findings, significance and major conclusions. The abstract often also includes a brief reference to theory or methodology. Many students just beginning their science education may be unfamiliar with the concept of an abstract in a lab report; it is often not required in introductory science courses because of its level of difficulty.
If your instructor gives you an outline for how to write a lab report, use that. Some instructors require the lab report be included in a lab notebook, while others will request a separate report. Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of.
