These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.
In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.
SHORT ANSWER:
Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
Answer:
water
Explanation:
Macromolecules contain a lot of atoms,whereas the water molecule contains only 3
Answer: hypotonic, isotonic, hypertonic
Explanation: The tonicity of a solution depends in part on its concentration of the solute that can not pass the membrane (non penetrating solute) relative to that inside the cell.
Hypotonic solution (hypo means less): contains less concentration of non penetrating solute relative to that inside the cell. Water will enter the cell and the cell will swell and late.
Isotonic solution (Iso means same): it contains thesame solute relative to that in the cell, there will be no net movement of water across the plasma membrane.
Hypertonic solution (hyper means more) Hypertonic solution contain more solute relative to that in the cell. Hence the cell will lose water to its environment and may shrink and die.
Answer:
Enzymes are influenced by changes in pH. Enzymes are best dynamic at ideal pH. It is the most favorable pH value - where the compound is most dynamic. Above and beneath to this ideal pH influence enzyme action. Accordingly enzyme show catalytic action at ideal pH.
At the point when enzymes are st low or high pH. Hydrogen particles interface with amino corrosive present at dynamic site. In this way changes their state of amino acids, their legitimate direction and influence enzyme movement.
While estimating action of enolase . 2 phospho glyceraldehyde is a substrate for enolase included a response tube. After appropriate in hatching measure of item is estimated (PEP). Proportion of PEP to 2 phospho glyceraldehyde gives thought regarding enzyme action.
For negative control, we will take a response tube, without having any enzyme enolase in it. Along these lines we will ready to preclude any change of 2 phospho glyceraldehyde to PEP without enzyme.
All compound present in our body are adjusted to as per the earth where we are living. In this manner makes us effective in C. aurantiacus ideal temperature for enolase is 55 degrees. So this catalyst will consistently work best at 55 degrees than at 37 degree

All elements are made of atoms
