Answer:
The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.
Explanation:
You have to think of it as outside vs inside the cell.
Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration. Energy keeps the ions going from the way they would naturally happen.
Answer:
Drowning: It is the suffocation that takes place due to submersion or immersion of the mouth and nose of an individual in a liquid or filling liquid in the lungs of the person. It caused death if an individual drowns completely.
Altitude sickness: physical discomfort at high altitude due to low oxygen pressure that causes hyperventilation, nausea, shortness of oxygen, concession. It is also known as mountain sickness.
Burn: It is an injury of skin or tissue that occurs due to heat, cold, chemical or radiation. Most of the time the burn takes place by heat contact to skin and cause different degree burn depends on the intensity of hotness or fire.
Electric shock: Electric shock is the event that occurs when an electric current passes through the body of an individual that can be mild to severe. It can burn the internal and external organs of an individual.
The correct answer is secondary structure of proteins is formed by the hydrogen bonding between amino acid chains.
Explanation:
The secondary structure of protein is generally stabilized by peptides bond along with hydrogen bonding between hydrogen atom and an electronegative atom such as oxygen.
The secondary structure both alpha helix and beta pleated sheet are stabilized by hydrogen bonding beside the presence of peptide bonds.

The major agent responsible for erosion on the Earth's surface is water. Flowing water as a result of rain, melting glaciers, moving streams and rivers erodes surfaces by displacing bits of soil and rocks, which is then moved from its original location to another.
