Water molecules bond to each other in a covalent bond where they stay connected. They also have poles like a magnet, making it a polar molecule.
If water is no longer polar the surface tension would lower to the point where ice can no longer float, the water would freeze, cooling the climate considerably.
Depolarization is initiated when there is an influx of sodium inside the cell as opposed to repolarization, where potassium exits the cell (occurring after Na+ gates close). Remember that for every 3 Na+ in, there is 2 K+ out. This imbalance helps to stabilize the membrane.
Elephants, who are important grazers, are instrumental in transforming woodlands into grasslands. This has a tremendous impact on other species that depend on the grass for their survival. The significance of the elephant in this example is B. keystone species.
Answer:
A
Explanation:
The components of salt water are chemically combined together and looks throughout, forming a homogeneous mixture.
Answer:
Just before the cat drops, it was stationery. Therefore it has energy of position called potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the ground all the energy is converted to P.E energy of position.
As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential energy) in the cat.
