It is characterized by patient or client suffering from it to have loss of memory, laughing or crying when it's unnecessary or at awkward times e.t.c it occurs as a result of damage of blood vessels in our brain or break down and it occurs as a result of stroke, diabetes and other factors.
Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.
Explanation:
Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
