Water is attracted to ions, such as sodium, potassium, phosphate, and chloride ions. Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of potassium and phosphate ions. Maintenance of extracellular water volume on the other hand depends primarily on the extracellular concentration of sodium and chloride ions.

Answer: unfavourable ph condition for the pepsin
Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .
As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.
In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.
As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
Answer: D. They are not well adapted to the Australian climate.
Explanation:
Just took the exam
Following are the statements:
1. Main phagocytes in circulation
2. Like eosinophils, they are involved in inflammation and allergic reactions
3. Phagocytic cells that leave circulation and differentiate into macrophages
4. Display no antigen specificity but are active against tumor and virally infected cells
Answer:
1. Neutrophils
2. Basophils
3. Monocytes
4. Natural killer cells
Explanation:
Neutrophils can be described as the most abundant type of white blood cells. They make up to 55%- 75% of the immune system.
Basophils can be described as white blood cells which are made in the bone marrow.
Monocytes can be described as white blood cells which are the largest and differentiate into macrophages and myeloid lineage dendritic cells.
Natural killer cells can be described as white blood cells which play a role in providing innate immunity.
