An ecology student noticed that Big Moose Lake has a higher nitrogen level than Brant Lake, but has lower algae growth. This dat
a surprised her, because algae often flourish in water with high nitrogen level. Develop a hypothesis to explain the surprisingly low algae growth in Big Moose Lake.
A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher level of nitrogen and nutrients in it.
Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in the water bodies and low oxygen content, the algae grows in slower rate. Besides, slower growth of algae may also affected by the acid rain that happens near Moose lake, which is harmful for algae growth due ti the presence of sulphur.
Stereo microscopes, also called low-power microscopes, dissection microscopes, or inspection microscopes, are designed for viewing "large" objects that are visible to the naked eye at low magnifications (under 50x). A stereo microscope provides an upright and unreversed, 3-dimensional image of the specimen.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
