Lipids have no polymers.
A lipid is formed when a glyceral combines with one or more fatty acids.
Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
Viruses are much smaller then cells, viruses have genetic material DNA or RNA and cells also have genetic material
Orthopneic
The client's paroxysmal dyspnea was probably caused by sleeping in bed with the legs at the level of the heart; this position increases venous return from dependent body areas, increasing the intravascular volume. Sitting up and leaning forward while keeping the legs dependent slows venous return as well as increases thoracic capacity. Although the contour position elevates the client's head, it does not place the legs in a dependent enough position to substantially decrease venous return. The recumbent position is contraindicated. Venous return increases when the lower extremities are at the level of the heart. Also, the pressure of the abdominal organs against the diaphragm decreases thoracic capacity. The Trendelenburg position is contraindicated. Venous return increases when the lower extremities are higher than the level of the heart. Also, the pressure of the abdominal organs against the diaphragm decreases thoracic capacity.
Work is force x distance.
