A student prepared four different blood cell suspensions, as shown in the chart below.
Note: Distilled water is water that has been boiled until it completely vaporizes, after which the water vapor is condensed back to liquid water. Distilled water is free from all organic and inorganic impurities and microorganisms, as they are completely removed during distillation. However, tap water contains high concentrations of ions, minerals, and other solutes.
Which of the solutions is MOST likely to cause the red blood cell to swell?

Suspension D because it is hypertonic

Suspension B because it is hypertonic

Suspension A because it is isotonic

Suspension C because it is hypotonic

Draggable item		Corresponding Item
Cell wall		Contains digestive enzymes to break down harmful substances
Chloroplast		Organelle that hugs the nucleus and has ribosomes attached to it.
Rough Endoplasmic Reticulum		Serves as a semi-permeable boundary between the cell and its environment.
Lysosome		Organelle in plants that uses light energy to make glucose in a process called photosynthesis.
Cell membrane		Firm, fairly rigid structure found outside of plants for support.

As part of a science class, a group of students went on a field trip to a nearby pond where they collected samples of pond water and a sample of a pond plant. The students used a microscope to study the cells within their samples and also a sample of their own cheek cells. Their observations are recorded in the table below.
According to the table, which pond organism was an animal?

pond organism #1

pond organism #2

pond organism #1 and #2

neither pond organism

If the ribosomes of a cell were destroyed, what effect would this most likely have on the cell?

It would stimulate mitotic cell division.

The cell would be unable to synthesize proteins.

Increased protein absorption would occur through the cell membrane.

Development of abnormal hereditary features would occur in the cell.

A cell membrane is composed of a double layer of lipids in which many kinds of proteins are embedded. Many of these proteins act like gates, allowing only certain particles to enter or leave the cell.
When a particle has to go against its concentration gradient through one of these gates, energy is supplied by the cell to the correct protein to move the particle through the membrane. A sodium‐potassium ion pump is an example of a type of carrier protein that uses a large portion of the cell’s energy to move sodium ions through the cell membrane.
The sodium‐potassium ion pump found in some cell membranes is made of which of the following basic structural components?

amino acids

fatty acids

monosacchrarides

nucleotides

The illustration above shows a cell and a large particle. Many substances, such as proteins and polysaccharides, are too large to be transported into a cell by carrier proteins. In a process called endocytosis, the large particle is brought into the cell. Which of the following statements correctly summarizes this process?

The cell membrane surrounds the particle and forms a vesicle that is brought into the cell.

The particle passes directly through a protein doorway in the cell membrane.

Waste materials can enter the cell by the same process.

The particle passes directly through the phospholipids that make up the cell membrane.

An osmosis investigation was conducted using chicken eggs to represent cells with semipermeable membranes. The mass of each egg was measured to determine how much water diffused into or out of the eggs. The eggs were first soaked in vinegar to dissolve the shell. Each egg was then placed in one of three different solutions for 24 hours. The table below shows the results of the investigation.
Based on this experiment, which of the following should be inferred about cells with semipermeable membranes?

Substances other than water may also cross the cell membrane.

Substances other than water may block pores in the cell membrane.

Water enters the cell when placed in environments of high water concentration.

Water leaves the cell when placed in environments with a low concentration of solutes.
