Answer:
Producers like plants get their energy from the sun. Consumers get energy from eating producers or other consumers.
Explanation:
Answer:
producers, primary consumers, secondary consumers and tertiary consumers
Explanation:
Producers get their nutrients by the sun, these are normally plants. Then primary consumers eat these producers, these are herbivores. The secondary consumers eat the primary consumers, these are carnivores and can be herbivores. Lastly, tertiary consumer eat the secondary consumers and are carnivores
Answer:
it increases speed of chemical reaction
Enzymes are proteins that speed up chemical reactions by lowering the activation energy, or the energy required for a reaction to take place. This makes reactions happen more efficiently and quickly.
An enzyme is a type of protein that accelerates, or catalyzes, chemical reactions. In relation to their effect on the energy of a chemical reaction, enzymes lower the activation energy. The activation energy is the energy threshold that must be met in order for a chemical reaction to occur. By decreasing this energy barrier, enzymes facilitate the process and make it proceed faster than it would without the enzyme.
For example, let's take the digestion of food in your body. The enzymes present in your digestive system speed up the chemical reactions that break down large food molecules into smaller units. This is because these enzymes reduce the activation energy required for these reactions, enabling the reactions to happen more efficiently and quickly.

Answer:
The correct answer is: The action potentials peak at a higher voltage than in the body.
Explanation:
Nerve cells in the human body have a very low sodium concentration inside them, while the liquid that surrounds them is rich in this particular ion. When sodium channels in the neuron's plasma membrane are opened, this big difference in sodium concentration -also called gradient- produces a big influx of sodium ions. This rapid entering of Na+ generates a change in the voltage of the cell, because sodium is positively-charged, meaning that the inside of the neuron will become less negative - this is commonly called depolarization of the membrane. Action potentials are generated because of the sudden spike in voltage, but for them to occur, there's a certain voltage that needs to be achieved, so not every depolarization will produce an action potential.
The fact that the cell in the lab is surrounded by a lower concentration of sodium means that the influx of Na+ ions will be lower, because the gradient won't be as big, but also means that the action potential will peak at a higher voltage because the resting membrane potential wasn't as negative to begin with.
