We theorized that the fresh water must bring elements needed for plant growth that are absent in seawater. We compared the composition of seawater to that of Zarrouk's algae medium. All the elements in algae medium are in sufficient quantity in seawater except for nitrogen, phosphorous and iron...
Theessential elements(or essential nutrients) are chemical elements that are absolutely needed by plants for their growth and development. Their essentiality has been established based on the following criteria formulated by D. I. Arnon and P.R. Stout (1939): 1.An element is essential if, being...

(b) Every mineral element that is present in a cell is needed by the cell. (c) Nitrogen as a nutrient element, is highly immobile in the plants. (d) It is very easy to establish the essentiality of micronutrients because they are required only in trace quantities. View Solution What...

Virtually nothing is known of the mechanism of early male killing, and research in this field is urgently needed. We now turn to the contribution that a study of A. bipunctata may make to considerations of the mci- dences of and evolutionary logic underlying male kill- SEX RATIO DISTORTION ...
TE have the potential to contribute to phenotypic variation in complex traits. By investigating the effects of TE activity on host fitness in livestock and poultry, researchers could identify areas where research is needed to improve animal health and productivity. However, current research on TE in...
important role in generating the variation needed to adaptation of various stressors and/or proliferation of TEs is triggered by stressful events. Although a clear causal and or mechanistical role of TEs in adaptation, like in many other systems is still lacking28,29, it is clear TEs have ...
