When air is blown into an object like a baloon balloon, the balloon expands because the amount of gas increases, which increases the number of gas particle collisions, thus increasing the gas pressure inside. what is responsible though? smeller's the feller.
a. The circulatory system in fish is one-directional while it is two-directional in humans.
b. P has a high concentration of carbon dioxide and low oxygen concentration whereas Q has high oxygen concentration and low carbon dioxide concentration.
<h3>What is the circulatory system?</h3>
The circulatory system is the system of organism and tissues which help to transport blood and other fluids through the body of a living organism.
The organs of the circulatory system include:
- The heart
- The blood vessels - veins, arteries, capillaries
a. In the given diagram sowing the circulatory system of man and the fish, it can be seen that the direction of blood flow in the fish is one way through the heart. However, in humans, the direction of blood flow is two-way through the heart.
b. The gas in P has a high concentration of carbon dioxide and low oxygen concentration. However, the gas flowing through Q has high oxygen concentration and low carbon dioxide concentration.
In conclusion, the circulatory system is important in the exchange of gases in the body.

Answer:
Hydronium ion
Explanation:
When acids are dissolved in water, the H+ ion reacts with H2O producing the H3O+ ion which is what makes the solution acidic
The specific heat capacity of sand is much less than water because of which sands require less energy to cool down and similarly less energy to be heated... because of this it feels like sands absrob heat faster than water
