Answer:
Central Vacuole ⇒ Storage
Explanation:
The complete question would be:
Which of the following correctly matches an organelle with its function?
A: nucleus ... cellular respiration
B: mitochondrion ... photosynthesis
C: central vacuole ... storage
D: ribosome ... manufacture of lipids
E: lysosome ... movement
The central vacuole is a fluid-filled organelle that works as a storage unit for nutrients for the cell and waste of the cell. The vacuole of the plant cell is much bigger than that of the animal cell. Another function of the vacuole is it acts as support for the cell structure by maintaining the turgor of the cell.
The herpes simplex virus and the human immunodeficiency virus are both transmitted sexually. These viruses take down the patient's immune system. However, when a patient is HSV positive doesn't mean he/she is also HIV positive. Nevertheless, a person that is being infected with HSV is most likely has the higher risk of getting HIV
The part of the eye that allows for varying amounts of light onto the retina is the Iris. <- Answer
Question options:
- How do hypotonic solutions prevent cells from surviving?
- How do freshwater organisms maintain homeostasis when placed into a
hypertonic condition?
- How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
- How does the temperature in which bags of dialysis tubing are placed directly impact the exchange of materials across the membrane?
Answer:
How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
Explanation:
The student is modelling osmosis using dialysis tubing, which represents a semipermeable membrane, much like the plasma membrane. During osmosis, water moves from a high concentration to a lower concentration across a semipermeable membrane. Therefore, when the dialysis bag is placed in high concentrations of sucrose, water will move out of the bag by osmosis.
The experiment does not deal with cells or organisms, so the first two options cannot be correct, and temperature is not assessed in the experiment. Therefore, the answer is "How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
