Answer: Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
Answer;
-Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.
Explanation;
-Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet.
-They protect coastlines from the damaging effects of wave action and tropical storms ( they provide a buffer, protecting our coasts from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion) and also provide habitats and shelter for many marine organisms.
Answer:
The correct answer is C) It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.
Explanation:
While replicating, the ends of the chromosomes always lose a part of the ends, therefore, the telomerase catalyzes this growing process, somehow compensating the information that will be lost.
Answer:
tire and balloons
Explanation:
the tire of an car contains gas pressure
the balloon also contains gas pressure because it contains gas molecules
Answer:
1 mol per dm3 sodium chloride solution
Explanation:
The liquid that would cause the largest decrease in the mass of the potato stick would be the one with <u>1 mole per dm3 sodium chloride solution.</u>
<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>
Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.
