Answer:

Exergonic reaction

Explanation:

  • A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.
  • An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
  • The energy that is released in the exergonic reaction is usually observed  in the form of heat and light.
  • The energy is released due to the breaking of the chemical bonds.
  • Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.

The red dots are salt. What type of solution is this cell in, and in which direction will
Leto [7]

Answer:

A) hypertonic, out of the cell.

Explanation:

When cells are exposed to high levels of salt (sodium chloride) they lose water by osmosis and shrink. The cytoplasm condenses and the movement of cellular components, such as the cytoskeleton and organelles, stops. Cells adapt to high salt by quickly importing salt in order to attract water and regain volume, at the expense of increased salt concentration. Unlike cell volume, the movements of cellular components are slow to recover and, depending on the dose of salt, may not recover fully.

What conversion factor is needed to change from kilometers to meters
Vesna [10]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

To convert from kilometers to meters, you would multiply by 1000

So, the conversion factor would be x 1000

This can also be written as x 10^3
