Answer: Electron Microscope is most appriopriate for studying living cells.
Explanation:
Most of the cells are so tiny that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study the behavior of cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.
The major demerits are size, maintenance, cost, researcher training and image artifacts resulting from specimen preparation. This type of microscope is a large, cumbersome, expensive piece of equipment, strongly sensitive to vibration and external magnetic fields.
Water's polarity can be responsible for many of it's properties including it's attractiveness to other molecules. Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of the other. Also the unequal sharing of electrons gives the molecules a slight negative charge near it's oxygen atom and a slight positive charge in it's hydrogen molecule.
Answer:
<u>O floating around one another in a fluid structure</u>
<u />
Explanation:
Cells are made up of varying types of molecules in order to achieve a fluid, stable plasma membrane. The membrane mainly consists of:
- lipids
- proteins
- cholesterol
Lipid membranes help maintain selective membrane permeability. The lipids, formed from glycerol and saturated/unsaturated fatty acids, are made up of polar heads and non-polar tails; they typically only allow the movement of <em>small non-polar molecules</em>. Larger molecules are <em>transported </em>through integral proteins; other types, are peripheral, and may have specialized functions like <em>cell signaling</em>.
Cholesterol molecules keep the lipids in place, and ensure membrane fluidity. In extreme temperatures, they help the membrane to maintain its shape without becoming too rigid.
