Answer:Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. ... The enzyme's active site binds to the substrate.
Explanation:
The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). ... Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.
In a lotus plant, stomata is found on the upper epidermis of the leaf.
Stomata are responsible for the exchange of gas with the surrounding atmosphere of the leaf. Their guard cells stay taut during the day to keep the stoma open.
Guard cells can only stay open if they are saturated with a certain quantity of water.
From this information we can infer that stomata are typically found on the lower epidermis to prevent water damage when it rains.
The rain would not only cover the openings, it would also ruin the osmotic balance of the guard cells causing inefficiency and damage to the cycle of gaseous exchange.
Natural selection probably selected against such plants giving rise to those with stomata on the underside.

<h3>What Is the Pathway of Blood Through the Heart?</h3>
There are four chambers in the human heart.
Mammals and birds have double circulation.
The pathway of blood through the heart is as follows:
- The deoxygenated blood from the body is received in the right atrium from the vena cava and enters the right ventricle through a tricuspid valve. It enters the pulmonary artery through the semilunar valve and goes to pulmonary circulation.
- The oxygenated blood from the lungs is received in the left atrium from the pulmonary veins and enters the left ventricle through the bicuspid valve. It enters the aorta through a semilunar valve and goes to the systemic circulation.
