If the earth traps more heat, it may cause Global warming.
A doctor need to study chemistry: To know and understand the chemicals processes of matter in the body work which is for example insulin, DNA etc. and to study of all processes in a living organism. The three reasons to study chemistry is because chemistry can be useful in clearing up the natural world, preparing people for career opportunities and producing informed citizens. Some outcomes of modern research in chemistry can lead to technologies that aim to benefit the environment, preserve and produce energy, progress human life and multiply our knowledge of the universe. To help the citizen be a more informed citizen is to let them know how things work makes better decisions and use them better
Answer:
The correct option is : a. Identification of the cell
Explanation:
The cell membrane, also called plasma membrane, is a semi-permeable membrane surrounding the cytoplasm of the cell, that protects and separates the interior of the cells from the external environment.
The carbohydrate layer of the cell membrane is known as the glycocalyx. In eukaryotes, <u>the carbohydrates present on the surface of the cell membrane play a important role in the cell-cell recognition and share information.</u>
1. tetrapods are ( four-limbed animals ) . examples of tetrapods include (extanct and extinct amphibians , reptiles , and mammals )
2. Tetrapods first appear in the fossil record ( 367.5 ) million years ago .
3. Charles Darwin predicted that tetrapods evolved from ( a finned organism that lived in the water) . What observation leads do that hypothesis?( they have “fleshy fins” and “lobe fins”) .
5. Fish use ( gills ) to breathe underwater .
<span>The movement of fluids between cellular compartments is regulated by osmotic and hydrostatic forces.</span>
<span>
Hydrostatic pressure<span> is the force exerted by a fluid against a wall which causes movement of fluid between compartments. This pressure is important for exchanging plasma and nutrients between capillaries and surrounding tissues</span> and also in the nephrons (kidneys) where ensures proper filtering of the blood to form urine.</span> <span>Fluid also moves between compartments along an osmotic gradient (the difference in concentration of solutes on one side of the cell membrane to that on the other side). Water constantly moves into and out of fluid compartments via osmotic gradient.</span>
