Answer: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Explanation: There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. ... A divergent boundary occurs when two tectonic plates move away from each other.
The correct option is this: A STRONG WIND BLOW ACROSS A MIDWESTERN PRAIRIE.
A strong wind is an example of a natural force. The prairie refers to a land fill with grasses and that is a natural factor also. Thus, a strong wind that is blowing across a prairie is generating a natural form of energy. The energy flow in the other options given are examples of man made devices.
Besides cell walls, features often found in plant cells but not in animal cells are: <span>· Chloroplast- specialized organelles in which light energy is converted to chemical energy during the photosynthesis(chloroplasts contain chlorophylls a and b-green color of the plant)

B
Area B of the graph shows the activation energy required if an enzyme was not present
Explanation:
Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.
Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.
