Sorry i only know some of these but here is what i know.
1. the chemical bonds are more attracted to the oxygen molecules because while the oxygen already have enough electrons, the oxygens still want more resulting in a bent shape.
2. polar
3. hydrogen bonds are formed
4.adhesive
5.high
6. water molecules bond from hydrogen bonds, and this causes the water to stick together forming cohesion. the water strider floats because the weight of the insect is less then the strength of the hydrogen bonds.
7. water is the universal solvent because it is a polar substance and most things will dissolve in it. usually fats will not dissolve in water ex. oil will no mix with water
Answer:
Option (C).
Explanation:
Membrane potential may be defined as the difference in the electric potential of the inside and outside of the cell. The resting membrane potential of neuronal cell is -70mV.
Pufferfish contains tetrodotoxin that blocks the voltage gated sodium channels. The movement of sodium ions inside the cell causes the depolarization of cell and makes the cell membrane potential towards more positive. This tetrodotoxin causes the normal resting potential but the cell are not able to depolarize if the stimulus is given to the cell.
Thus, the correct answer is option (c).
The answer is 50%.
The-related number of thumps every moment of the heart when working at its greatest that is generally evaluated as 220 short one's age achieved 90 percent of his most extreme heart rate when tried on a treadmill.
It is prescribed that you practice inside 55 to 85 percent of your most extreme heart rate for no less than 20 to 30 minutes to get the best outcomes from oxygen consuming activity. The MHR (generally ascertained as 220 less your age) is the maximum furthest reaches of what your cardiovascular framework can deal with amid physical movement.
A whole number ratio; Hopefully that is the answer if you need an actual number the best guess would be 2:1.
