Explanation:
D) Letter Y represents runoff
Answer:
Kinetic<thermal+ sound energy.
Explanation:
As Edward rides his bike, as his speed increases, the bike has kinetic energy as it is set in moving and kinetic energy is the energy posses by a body in motion, it is the energy that accelerate a body from rest and maintains the motion. As he goes down the hill, when he apply the break which decreases his speed, the energy is transformed to thermal energy or heat and also transformed sound because the sound can be heard.
THE ELECTRON TRANSPORT CHAIN is responsible for releasing energy that is used to pump hydrogen ion. The energy which is released in form of electrons are passed through the electron transport chain and used to pump protons into the thylakoid compartment of the plant cell.
The nature of the indicated covalent bond is: Polar
<h3>Meaning of Polar covalent bond</h3>
A polar covalent bond can be defined as the chemical bond which occurs or can be formed when one of the element possesses more electronegativity than the other, causing the shared electrons to be closer to an element with the higher electronegativity than the other with a lower electronegativity.
In Polar covalent bonds the electro-negativity difference is between the value of 0.5 to 1.7
Electronegativity is the abiliy for an element's atom to attract electrons in a chemical reaction.
In conclusion, The nature of the indicated covalent bond is: Polar
