1) the manipulative variable is the salt
2) the responding variable is how many purple eggs hatched
3) beaker A was the controlling variable
Answer:
- They allow for more collisions of molecules (enzymes + substrates)
- They lower the amount of activation energy needed to complete the reaction.
- They speed up chemical reactions to form more products
Explanation:
Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).
Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.
The lateral hypothalamus signals an animal to start eating, whereas the <span>ventromedial </span>hypothalamus signals the animal to stop eating. So the correct option is the first one.
Don't pollute the Earth.
Don't need gas.
Thanks for the news. We'll look forward with great anticipation to any reports of the results of that experiment. Then, if the findings raise any questions in your mind that you'd like to discuss, we'll certainly help you work on them.
