The term would be leukocytosis and this usually indicates that there is presence of an infection.
A sound wave is A wave of compression and rarefraction .
It serves to polarization by transmission through a filter. <span>A Polaroid filter is a device used to polarize light. The device filters out one-half of the vibrations of unpolarized light as the light passes through the filter. Unpolarized light enters the Polaroid filter and the polarized light goes out from the filter. The unpolarized light becomes polarized.</span>
Anthropoid
Pretty sure that is right B/C they have a exoskeleton, they are land animals primarily (Oxygen Tubes), they have joints and have two body segments.
Explanation:
Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.
Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.

= 300 g
Thus, we can conclude that weight of Tris-HCL required is 300 g.
