Many other types of algae, e.g. hair algae, is a signal to the aquarist that something has gone wrong with the water quality, but green algae is known to occur even in aquariums with perfect water quality. If the green algae start growing much faster than before, there is however a ...
Many algaes use nitrates as a food source. In this case, I recommend keeping the nitrate levels below 10 ppm. This helps deprive the algae of its food source, making it easier to eradicate. FishLab Fact:The“lower nitrates are better”rule is thrown out the window if you have a planted...

a type of algae that forms in freshwater. These remains are ground up into a soft, fine white powder that carry many different uses. It’s chemical free and completely safe to use around children and pets.

A significant difference in the amount of corals overgrown by algae was found on the reefs near Hurghada as compared to all other reefs. Algal overgrowth was correlated with the occurrence of tissue loss and breakage, being considered as a consequence of pollution or the former damage types. In...

The differentiation, activation and expansion of T cells are dictated by their integrated response to a complex array of extracellular signals. Recent studies provide insight into how these signals are integrated and demonstrate a key role for cell shape in many aspects of T-cell signalling. T cel...
Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own quest
