C
The main function of the Krebs cycle is to transfer high energy electrons to the electron transport chain using the carriers used in Krebs cycle.
Answer/Explanation:
Normal cell division is a very controlled process.
There are several checkpoints where the cell ensures the cell is:
- receiving the correct signals to divide
- that the environmental conditions are favourable for the cell to divide
- that there is no damage to the DNA.
However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.
A hypotonic solution is a solution in which there is a lower concentration in solutes (ex. salt) dissolved in the solvent (ex. water). A hypertonic solution would be one in which there is a higher concentration of solutes in the solvent.
Answer:1. forecasting
2. potential
3. neglected
4. seismic retrofitting
5. Fu kushima Daiichi Nuclear Power Plant
6. The best way to determine how strain accumulates in a fault is with GPS measurements of plate motion. As ground on each side of a fault moves, the potential energy that accumulates in a fault can be estimated and used to forecast the rough timing, magnitude, and location of an earthquake.
7.When seismic waves travel through the earth, they refract along different directions, creating seismic shadow zones. The size and distribution of seismic shadow zones can be used to determine whether different layers are solid or liquid as well as the size of each layer.

Explanation:
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology.
