To determine which statements are correct and which are wrong regarding blood and its components, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement 1: Plasma constitutes `45%` of blood.** - This statement is **wrong**. Plasma actually constitutes about **55%** of blood, not 45%. 2. **Statement 2: Albumin is a plasma protein involved in osmotic balance.** - This statement is **correct**. Albumin is indeed a plasma protein that plays a crucial role in maintaining osmotic pressure in the blood. 3. **Statement 3: Blood clotting factors are present in blood.** - This statement is **correct**. Blood contains clotting factors, which are essential for the coagulation process. 4. **Statement 4: Plasma without clotting factors is serum.** - This statement is **correct**. Serum is defined as the liquid portion of blood that remains after clotting factors have been removed. 5. **Statement 5: Minerals are not found in blood.** - This statement is **wrong**. Blood contains various minerals such as sodium, calcium, magnesium, and chloride. ### Summary of Statements: - **Statement 1**: Wrong - **Statement 2**: Correct - **Statement 3**: Correct - **Statement 4**: Correct - **Statement 5**: Wrong ### Conclusion: The correct statements are **2, 3, and 4**, while statements **1 and 5** are incorrect. ### Final Answer: The correct option is that **statements 2, 3, and 4 are correct, while statements 1 and 5 are wrong**. ---
