Explanation:
Surface tension is the property of water which allows for some lightweight insects to walk on top of a pond and not fall in. The molecules of water are held together by cohesive forces. The molecules of water present below the surface experience this cohesive force from all the directions, whereas the water molecules present on the surface experience a downward pull, as the force is not balanced. This leads to the concaving of the water surface inside a small tube.
The way I'm interpreting this is that what type of bound are these? And yes share electrons in various bonds can share electrons lose and gain, these all sounds like covalent bonds and ionic and hydrogen bounds are from.single to double and to triple bounds.
Most mutations have no effect on organisms. Organisms all have large amounts of genetic code, most of which has no effect. As a result, mutation of this code is rarely meaningful.
