The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environment. What conditions cause the contractile vacuole to fill with water ?
The concentration of water is greater outside the cell than inside the cell.
The temperature of water in the vacuole is higher than the temperature of its environment.
the concentration of water inside the cell is the same as the concentration outside of the cell.
The temperature of water in the vacuole is lower than the temperature of its environment.
Some students use vinegar to dissolve away the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions.
Which statement best describes the role of the cell membrane in this model ?
The cell membrane is an impermeable barrier that prevents water from entering the cell.
The cell membrane allows solutes to enter the cell, which causes the cell to shrink
The cell membrane allows water to enter and leave the cell
The cell membrane removes solutes from the environment.
Diffusion and osmosis are both vital to cell function. Diffusion and osmosis are similar in that they are both types of
protein synthesis
Passive Transport
Cellular replication
Cellular metabolism
This diagram shows proteins embedded in the lipid bilayer can move around and “float” among the lipids, scientists describe the cell membrane as a phospholipid bilayer. Which statement explains why the structure shown is important in maintaining homeostasis?
It packaged cell products for export
It transfers hereditary material to offspring
It regulates the movement of materials in and out of the cell
It prevents a cell from bursting due to osmosis
Which of the following scenarios represents an example of osmosis?
Blood vessels transport glucose to cells
Carbon dioxide waste is eliminated during respiration
Limp celery becomes crisp in water
sweating lowers body temperature
The diagram shows the concentration of solutes inside various containers. If you connected container A to container C, which direction would the solutes move?
From container A to container C with the concentration gradient
From container A to container C against the concentration gradient
From container C to container A with the concentration gradient
From container C to container A against the concentration gradient
Which of these describes a difference between viruses and cells ?
Cells contain protein and viruses contain only carbohydrates
Viruses have flagella and cells have only cilia
Cells reproduce independently and viruses require a host to reproduce
viruses have membranes made of proteins and cells have membranes made of nucleic acids.
Which of the following is not a function of proteins
catalyze reactions that are essential to metabolism
provide structure for muscles
growth and maintenance of tissues
provide insulation for animals
