The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. ... The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body.
The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
Explanation:
<span>4 is a good answer. The question ‘can planting cover crops reduce erosion’ can be easily answered by creating a scientific study. You could create an experimental group where cover crops are planted and a control group where they are not, and measure the erosion of each group. </span>

Answer:
This question have two parts.
Question 1. Is a 0.185 M aqueous solution of sodium sulfate, Na2SO4, hypertonic, hypotonic or isotonic to red blood cells?
Answer:
Hypotonic because sodium sulfate is a detergent which can cross the lipid bi-layer.
Question 2. If normal red blood cells were suspended in this Na2SO4 solution, what would be the expected outcome?
Answer:
Hemolysis (Bursting of Red blood cells) will occur due to excessive movement of water inside the cell resulting from sodium sulfate solution.
