Answer;
Semi-permeability means that only certain molecules are allowed to pass through.
Explanation;
-Semi-permeability is one of the features of a cell membrane, which means that the membrane allows selective movement of materials in and out of the cell; that is only certain molecules can enter or leave the cell.
-For example smaller molecules such water and ions such as potassium and sodium ions are able to leave and enter the cell, while other molecules that are large such as protein molecules can not enter or leave the cell.
Answer:
In my own words, this summary equation tells me that:
When glucose reacts with oxygen, carbon (IV) oxide and water are given off and energy is produced.
Explanation:
Cellular respiration is known to be a metabolic reaction which actually occur in the cells of living organisms whereby chemical energy is converted into energy (ATP) and certain waste products, carbon (IV) oxide and water are released. We can simply put that cellular respiration is a process of converting sugars to energy. In the giving equation, we can see that glucose which is a sugar reacts with oxygen to give CO₂ and H₂O.
The area around the rock will have weathered down and the rock will eventually either break or it will fall down the mountain
I would say that C. Is the most correct answer. Hope this helps! :-)
