DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
Explanation:
In agriculture, postharvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. The instant a crop is removed from the ground, or separated from its parent plant, it begins to deteriorate.
Nails start in the nail root, hidden under the cuticle. When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly fromed nail then slides along the nail bed, the flat surface under your nails.
A. The waves would be exactly the same at points A and B.
Explanation:
The seismic waves at both point A and B would be exactly the same at the two points.
Seismic waves are elastic waves that spreads out concentrically in all directions from their source.
- Both S and P waves are body waves that moves within the earth.
- In a seismic station, the p-waves or primary waves arrives first before the s-waves or secondary waves.
- At any point equidistant from the epicenter, baring any geologic differences in the subsurface, the waves would be exactly the same at all points.
