A biologist working in a lab receives a sample of an unidentified organism. After some analysis the organism has the characteristics listed in the table
Which of the following students' correctly justified their identification of the organism?
Sarah said the cell is a Prokaryote because the DNA is not housed within a nucleus.
Devon said the cell is a Prokaryote because it is small in size.
Marissa said the cell is a Eukaryote because it has a cell wall.
Alvin said the cell is a Eukaryote because it has DNA.
A student was observing the effect of temperature (°C) on enzyme reaction rate. Their results are shown in the graph. Which conclusion can be supported by the information in the graph?
The optimal temperature for the enzyme is about 48°C.
The optimal temperature for the enzyme is about 0°C.
The optimal temperature for the enzyme is about 60°C.
The optimal temperature for the enzyme is unknown.
a. In passive transport, molecules move from an area of (a) concentration to an area of (b) concentration.
a. In active transport, molecules move from an area of (a) concentration to an area of (b) concentration.
Which of the following is best supported by the information in the graph?
Gastric protease functions best in acidic environments.
Gastric protease functions best in neutral pH.
Intestinal protease functions best in basic environments.
Intestinal protease functions best in acidic environments.
Red blood cells have been placed in different solutions. The cells are 30% salt, and the percentages in each image indicate the concentration of salt in each of the solutions. Which of the following are true concerning the environment of the cell pictured? Select all that apply:
The cell is in a Hypotonic solution.
Water will move out of the cell.
Water will move into the cell.
The cell is in a Hypertonic solution.
The cell will shrink.
The diagram shown represents some events that take place in a cell. What process is being modeled in the diagram and which organelle would these events most likely occur?
Cell Respiration / Mitochondrion
Photosynthesis / Mitochondrion
Cell Respiration / Chloroplast
Photosynthesis / Chloroplast
Chemosynthesis / Mitochondrion
What would likely occur if the cell pictured was infected with a virus that destroyed the structure labeled E?
The cell would not be able to grow and divide.
The cell would not be able to create proteins.
The cell would not be able to capture energy to make food.
The cell would not be able to store genetic information.
Which structure is present in plant cells but not in animal cells?
Nucleus
Cell wall
Ribosomes
Lysosome
Which organelle is involved in regulating the flow of materials in and out of the cell?
Nucleus
Cell membrane
Chloroplasts
Golgi apparatus
What is the primary role of chloroplasts in plant cells?
To store waste products.
To convert light energy into chemical energy.
To regulate the flow of materials.
To provide structural support.
The diagram shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur. Which statement describes how photosynthesis and cellular respiration are interrelated?
Oxygen is produced during cellular respiration and stored during photosynthesis.
Carbon dioxide and water released by cellular respiration are used during photosynthesis.
Photosynthesis releases the energy that is stored during the process of cellular respiration.
Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.
A student is performing an investigation using two solutions. The solution in the dialysis bag has a lower solute concentration in moles per liter (M) than the solution in the beaker.
Label the description in the boxes under dialysis bag and the beaker to describe each solution as either Hypertonic, Hypotonic or Isotonic.
Which of the following presents the best argument as to the role of the tree in this cycle?
The tree uses energy from the sun and through the process of photosynthesis it releases oxygen back into the atmosphere. The sheep then uses that oxygen to produce energy through cellular respiration.
The sheep uses energy from the sun and through the process of photosynthesis it releases carbon dioxide back into the atmosphere. The tree then uses that carbon dioxide to produce energy through cellular respiration.
The sheep eats plants and produces carbon dioxide through cellular respiration. The plants, which gain energy from the sun, then take carbon dioxide from the atmosphere and use it in photosynthesis.
The tree uses carbon dioxide from the atmosphere to conduct cellular respiration. The sheep, which releases oxygen through cellular respiration, gains carbon dioxide from the plant when it is eaten.
Match the following monomer structures to their correct function.
codes for genetic information
long-term energy storage
easily digested to produce usable energy
synthesize proteins for regulation
