The lipid bilayer<span> has been firmly established as the universal basis for cell-</span>membrane<span> structure. It is easily seen by </span>electron<span> microscopy, although specialized techniques, such as x-ray diffraction and </span>freeze-fracture electron microscopy<span>, are needed to reveal the details of its organization.

The answer is that "both are produced in the red bone marrow. Red blood cells transport oxygen, and white blood cells protect the body against diseases."

The right answer is B.
*Hydrogen is the most abundant element representing nearly three quarters of the mass of the universe.
*Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter.
*Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).
*Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table.
*Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.
The solution of wet mount should be hypertonic solution.
<h3><u>Explanation:</u></h3>
Wet mount is a preparation where the specimen is made to place in a glass slide and a drop of solution is put on the slide. The wet mount is primarily used to see vaginal swab, bacterial slides etc.
Here the wet mount uses a hypertonic solution which is primarily 30 to 40% salt solution in distilled water. The function of this solution is to draw water from the cells and to keep them dehydrated.
The dehydration of the cells maintain their shape, and help to keep any stain if provided. So wet mount uses a hypertonic solution.
Answer:
4 significant digits
Explanation:
non-zero digits are always significant, and zeros in between significant digits are also significant.
