Carmen's teacher told her she made one mistake. Which comparison should Carmen change?

• Lysosome. It should be compared to a bank.

• Mitochondria. It should be compared to the police.

• Nucleus. It should be compared to a neighborhood.

• Ribosome. It should be compared to a construction site.

Multiple Choice

Which of the following sets of elements has the most similar physical and chemical properties?

• K, Ca, Sr

• K, Cs, Fr

• K, Ca, Rb

• K, Sr, Li

Multiple Choice

Examine the portion of the periodic table that contains neon, an unreactive gas in Group 18.

Which element would have similar properties to neon, and why?

• Ar; elements in the same family of the periodic table share the same characteristics.

• H; elements on opposite corners of the periodic table share the same characteristics..

• B; elements in the same period of the periodic table share the same characteristics.

• Li; elements on opposite sides of the periodic table share the same characteristics.

Multiple Choice

Examine the diagram that shows the levels of organization of an organ system.

If level 2 becomes diseased, what is a possible consequence?

• The organ system will generate more cells to create a new organ to replace the diseased component.

• The organ will fail to function properly, affecting the organ system and consequently the organism.

• The cells will bypass creating tissues, creating the organ directly to limit the spread of the disease to the organism.

• The organ will temporarily shut down until the disease is repaired with the replication of new cells.

Multiple Choice

Esmahan constructs a model to show the structural organization in humans, as shown. 

Which statement explains how each level of the organization is created?

• Two or more types of muscle tissues working together make an organ.

• Two or more types of organs working together make a cell.

• Two or more types of organ systems working together make a tissue.

• Two or more types of muscle tissues working together make a cell.

Multiple Choice

The reaction of calcium and zinc carbonate is represented by this chemical reaction.

What would be the amount of zinc formed in the reaction?

• The mass of zinc produced will be 104 g.

• The mass of zinc will be the same as that of zinc carbonate.

• The mass of zinc produced will be 52 g.

• The mass of zinc will be the same as that of calcium.

Multiple Choice

Kaylon performs an activity in which a soluble colored substance is dropped in a beaker filled with water, as shown in the figure.

Which statement explains why the water in the beaker is a uniform color after a period of time?

• The molecules of the colored substance move randomly through the water, with the majority moving from an area of high concentration to an area of low concentration.

• The water molecules are altered and replaced by the molecules of the colored substance.

• The molecules of the colored substance move randomly through the water, with the majority moving from an area of low concentration to an area of high concentration.

• The colored substance molecules are altered and replaced by the molecules of the water.

  The colored substance molecules are altered and replaced by the molecules of the water.

Multiple Choice

Mijion observes two different types of cells (P and Q) under a microscope and records observations about the cell structures in a table.

Based on the observations, how can Mijion classify Cells P and Q?

• Cell P is a bacterial cell, and Cell Q is a protist.

• Cell P is a protist, and Cell Q is a bacterial cell.

• Cell P is a bacterial cell, and Cell Q is a plant cell.

• Cell P is a plant cell, and Cell Q is a bacterial cell.

Multiple Choice

Aminat reads that sodium atoms (Na) react with chlorine (Cl₂) molecules to form the compound sodium chloride (NaCl). Which model should Aminat make to satisfy the Law of Conservation of Matter for the formation of sodium chloride, in simplest form?

Multiple Choice

Londin constructs two diagrams that show the states of two plants and their cells.

According to her diagrams of the plant cells, what causes the difference in the two plants?

• The mitochondrion, which only stores gases for respiration by the leaf cell, has shrunk, causing the plant to wilt.

• The mitochondrion, which stores food and provides energy to the leaf cell, has stopped working, causing the plant to wilt.

• The vacuole, which stores water and helps maintain the shape of the leaf cell, has shrunk, causing the plant to wilt.

• The vacuole, which stores waste products for elimination from the cell, has stopped working, causing the plant to wilt.

Multiple Choice

The table shows a list of characteristics of the kingdoms of four unknown organisms. A teacher asks her students to classify the four organisms into their kingdoms.

Which student correctly classifies the organisms into their kingdoms?

Multiple Choice

The diagram shows the formation of water from hydrogen and oxygen.

Which statement is true?

• The reaction satisfies the Law of Conservation of Matter because only one type of substance is formed as a product.

• The reaction satisfies the Law of Conservation of Matter because the number of each type of atom is the same in the products and reactants.

• The reaction does not satisfy the Law of Conservation of Matter because the atoms are in different arrangements in the products and reactants.

• The reaction does not satisfy the Law of Conservation of Matter because the new substance formed is made up of two types of atoms.

Multiple Choice
