<h2>Answer 1:</h2>
The carbon dioxide in the breathed out air is a by-product of the process of cell respiration. In respiration, a molecule of carbohydrate is converted into a CO2, H20, and energy which is released in form of ATP.
<h2>Answer 2:</h2>
All plants belonging to kingdom Plantae and plant-like organism like photosynthesizing bacteria need CO2 to survive. They use carbon dioxide in food making process, photosynthesis.
<h2>Answer 3:</h2>
- Amount of CO2 in the air: 0.03%
- Amount of CO2 in the breath: 4%
Hence it is proved from above statistics that breath has more carbon dioxide than air.
<h2>Answer 4:</h2>
There are two sources of CO2 in the air. Which are the following:
- Human sources: It includes activities of human involvement and release of CO2 artificially as in cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
- Natural sources: Release of CO2 by natural processes as in decomposition, ocean release and respiration.
<h2>Answer 5:</h2>
- The major ecological effect is global warming.
- As CO2 is known as the greenhouse gas because it gives a greenhouse effect. Elevating concentration of CO2 in air forms a layer or sheath of CO2 over the earth which allows the entry of sun rays and stop it from reflecting back, trapping sun rays around earth increasing the temperature of earth day by day.
- It also causes plants to provide less evaporative cooling because in high concentration CO2 stomata shrink through which normally evaporation occurs when stomata are open.

Yes it is true, that when a solute and solvent are equal on both sides of the membrane it has achieved an osmotic equilibrium. Osmosis refers to the spontaneous movement of solvent molecules through a semi-permeable membrane. Usually the movement is that the solvent moves from a higher solute concentration into a direction that it tends to equalize both solute concentrations on both sides.
Answer:
Approximately 90% of all living plants are group of Angiosperm
This experiment lends credence to the fact that water diffuses down a concentration gradient.
<h3>What is Osmosis?</h3>
The term Osmosis refers to the movement of solvent molecules through a semipermeable membrane, from a region of higher concentration to a region of lower concentration.
In this case, the solvent molecules travel from the concentrated sugar solution to the potato. This movement of the solvent molecules depends on the difference in the concentration of the sugar solution in both parts.
3) The sucrose flowed in and out of the potato depending on the concertation of the sucrose solution
4) The concentration of the sucrose solution in the potato was greater than 0.4 M but less than 0.6.
5) This experiment lends credence to the fact that water diffuses down a concentration gradient.
