Answer:

Thermoelectricity

Explanation:

A thermal power station is a power station in which heat energy is converted to electric power.These types of power plants, called thermoelectric or “thermal” plants, boil water to produce steam for generating electricity. In most places the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.

Hope this helps!!

Answer:

Tidal energy is used for the production of electricity from water.

Explanation:

In tidal energy, tides of water is used as a source of energy which is converted into other forms of energy, especially for electricity production. It is low cost electricity production method. Tidal plants are installed inside the water on the shore of sea where tides are in great amount. The energy produced from it is clean because it does not pollute the environment.

1.What changes occur to chemical bonds during a chemical reaction?
mr_godi [17]

1.What changes occur to chemical bonds during a chemical reaction?

The chemical bonds will be altered or rearranged in chemical reaction. The bond that exist prior of the reaction could be separated or new bond will be formed. The rearrangement of the bond will change the properties of the molecule.


2.How does the change in energy of a chemical reaction predict whether or not the reaction will occur?

Chemical reaction happens when some subtrate molecule/atom collide. To start a chemical reaction there will be a certain amount of energy needed called activation energy. If the energy is not reaching activation energy, the reaction will not occur.


3.Explain the role of enzymes and how they affect the chemical reactions of living things.

Enzyme help chemical reaction by lowering the activation energy of the reaction, make the reaction faster and easier. Living things need to do some chemical reaction to produce and utilize energy. Enzyme could help those reaction, make the organism to produce and utilize energy faster. This will help the living things to fulfill their energy needs.


4.Explain why a key that fits into a lock is a useful model for the function of enzymes.

Key and lock model state that the enzyme is like a key that could only work with a certain type of lock. This because the enzyme has a specific active site in their three dimensional structure that could hold a substrate, and help the chemical reaction. Enzyme only work with substrate that could be hold by their active site, same as "lock" could only work with specific "key".


5.Explain how consuming an acid-neutralizing antacid might affect protein digestion.Apply the concept of activation energy to support your explanation.

Protein digestion happens in the stomach by pepsin enzyme. The ideal condition of the enzyme to work is in acid pH. Using antacid will cause the pH to become neutral. This will alter the enzyme structure, make the enzyme didn't work. If the enzyme didn't work, the activation energy will be much higher and protein digestion will be slower.


6.Predict which temperature ----(20degrees Celsius ,39 degrees celsius, or 50 degree Celsius) --- you would expect a human enzyme to function best.Plan a simple investigation to test your hypothesis.

Human is a warm blooded mammals that keep their body temperature around 37 degrees celsius. The ideal condition of human enzyme activity would be around that temperature. From the option, 39 degrees would be the most appropriate as it was the closest to 37 degrees.

You can investigate this by taking some enzyme and examine their speed in container with different temperature.

Which of the following is not a current theory regarding global climate change?
deff fn [24]

Answer:

Explanation:

“Higher levels of carbon dioxide in the atmosphere will have no effect” is not a current theory regarding global climate change.

 Global warming refers to the recent and ongoing rise in global average temperature near Earth's surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. Global warming is causing climate patterns to change

The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

The action potential spreads through an axon by Group of answer choices depolarizing adjacent membrane to threshold, triggering
Step2247 [10]

The action potential spreads through an axon by depolarizing adjacent membrane to threshold.

  • K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
  • Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
  • Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
  • Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is  is greater inside the cell than outside.
