A cell is in ISOTONIC SOLUTION when solute concentrations inside and outside the cell are equal.
<span>When cells are in isotonic solution, movement of water out of the cell is exactly balanced by movement of water into the cell</span>.
Other movement of water in the cells are hypotonic solution and hypertonic solution. Hypotonic solution is where concentration of dissolved solutes are less outside the cell than inside it. Hypertonic solution is where concentrations of dissolved solutes are greater outside the cell than inside it.
Answer:
Spiders have 2 body segments. The front is called a cephalothorax or prosoma and the abdomen, also known as opisthosoma.
Hope this helps :)
The main reasons for testing light intensity are to ensure that minimum standards of illumination are being met, and to determine appropriate exposure times in photography and cinematography.
Four commonly encountered situations are set out,from which i will describe on way to test light intensity;
<u>WEATHER MONITORING:

While many light meters are configured for incandescent light they are still useful for providing comparisons outdoors. A meter could for example produce records showing the difference in intensity between the summer and winter solstice. Mapping light intensities in an area designated for solar arrays could help determine the optimal location for each panel. Those involved in agriculture may benefit from identifying areas of lower light intensity within a greenhouse.
