Number of grams of salt in one kilogram of water is the best description of the salinity of ocean water.
Salinity is a measure of dissolved salts in water bodies such as oceans, rivers, seas etc. Salinity is calculated as the amount of salt (in grams) dissolved in one kilogram (1,000 grams) of seawater. Sodium chloride are the main salts with other elements such as magnesium, calcium and potassium that can be found in sea water.
Yes. all life on the earth would come to an end.
Reason- oxygen is important for survival on earth. so plants are the pnes providing oxygen and if they are not present then we will all die.
Answer;
-High specific heat
Explanation;
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. Water has a large heat capacity which helps limit changes in body temperature in a warm or a cold environment.
Water enables the body to release heat when ambient temperature is higher than body temperature An individual begins to sweat, and the evaporation of water from the skin surface cools the body very efficiently. As a result, water plays a very important role in temperature regulation.
Answer:
A) A decrease in Na+ permeability, and an increase in K+ permeability.
Explanation:
When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell K+ permeability while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels so as to restore the charge valance, that means that there is an increase in K+ permeability.
