Julie listed out fossil fuels are a non-renewable source of energy and Fossil fuels are becoming more expensive.
Option C
<h3><u>Explanation:</u></h3>
Fossil fuels are defined as the type of non renewable energy which is formed as a result of dead and decaying organic matter over thousands of years under pressure and temperature of Earth’s core.
This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.
Answer:
B (active transport using ATP)
Explanation:
Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.
In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).
An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.
Earth's rotation causes the Coriolis effect.
