Plasma constitutes about 55% of the total blood volume. Plasma is a yellowish liquid that carries cells, nutrients, hormones, and waste products. - **Conclusion:** This statement does not match correctly. **Hint:** Plasma is the liquid component of blood and is more than half of the total blood volume. 3. **Analyze the Third Statement:** - **Statement:** Hemoglobin is about 12 to 16 grams per 100 ml of blood. - **Evaluation:** This statement is correct.
