Answer:
Sodium-Potassium Pumps
Explanation:
Sodium-Potassium Pumps written as Na-K Pumps are ion channels found in the cell membrane of nerve cells. These pumps are responsible for maintaining the different ion concentrations across the membrane and help in polarization and depolarization of the membrane by influencing membrane potential. During ion exchange these pumps transfer three sodium ions from inside to outside of the cell and two potassium ions from outside to inside of the cell. In this way they maintain the ion concentration gradient across membrane.
The result would be: loss of farmland
Answer:
When these materials end up in the ocean, they support the growth and well-being of marine life.
Explanation:
This is the incorrect statement
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction … , and in any actual reaction, the same exact atoms will be found on both sides of the equation.
Answer:
Option C is correct.
The minimum amount of material that is needed for a fission reaction to keep going is called the critical mass.
Explanation:
Nuclear fission is the term used to describe the breakdown of the nucleus of a parent isotope into daughter nuclei.
Normally, the initial energy supplied for nuclear fission is the energy to initiate the first breakdown of the first set of radioactive isotopes that breakdown. Once that happens, the energy released from the first breakdown is enough to drive further breakdown of numerous isotopas in a manner that leads to more energy generation.
But, for this to be able to be sustained and not fizzle out, a particular amount of radioactive material to undergo nuclear fission must be present. This particular amount is termed 'critical mass'
