Thus, Cactus survive with the help of its "green stems" and "transpiration".
Should be position one since the Northern Hemisphere is leaning towards the sun.
This study lacks generalizability.
Generalizability is an academic term and describes the process of extending research findings and observations from a study on a sample population to a larger and more diverse population. The larger the sample population, the easier will be to generalize the results to the wider population. In this example, Dr Kirch used a sampling technique called convenience sampling, which involves the selection of the most available and proximate subjects. However, there is sampling bias since the sampling population is not representative of the entire population and therefore the study can not speak for the entire population.
The disk diffusion test is used to compare the effectiveness of antibiotics. The incubated plate (results) will show bacteria growth except where antibiotic has effects. The more effective the drug, the inhibition zone will be greater. So the most effective antibiotic is the one that has the largest inhibition zone around the test site.
