The diagram below represents a laboratory experiment involving sucrose and water
molecules in a cellophane bag which functions in the same way as dialysis tubing. Which
statement correctly explains the rise of liquid in the tube at the end of the experiment?
Glass tube
DOVO
Rubber stoppor
GO
Rubbor band
Key
- Sucrose moleculo
- Water molecule
Colophano bag
At boginning of
experiment
At end of
experiment
The concentration of sucrose molecules increased as water molecules entered the bag. This
concentration increase pushed the liquid up the tube.
Water entered the bag dues to the lower concentration of water inside. The extra water pushed the
liquid up the tube as the bag filled.
Sucrose indicator entered the bag and reacted with the sucrose molecules. The reaction made the
bag increase in size and pushed the liquid up the tube.
Sucrose molecules moved out of the bag and up the tube while water moved out, causing the rise of
liquid in the tube

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
