Bob and Candy Had to create a model of an animal cell.

Which statement BEST explains whose model is correct?

• Bob’s model is correct because it has only a cell membrane enclosing the cell organelles, and this is correct for an animal cell.

• Candy’s model is correct because it has a cell wall, and a cell wall is found in an animal cell.

• Bob’s model is correct because it contains a nucleus, and animal cells are the only types of cells that contain a nucleus.

• Candy’s model is correct because the cytoplasm is between the cell wall and the cell membrane, and this is where cytoplasm is located in an animal cell.

Mr. Hart’s class was discussing learned and instinctive behaviors. He created a diagram to help the students compare and classify different behaviors.

Which would be the BEST question for the class to use to complete the chart and determine if any trait is learned or inherited?

• Were you born knowing how to do that?

• Did someone teach you how to do that?

• When did your parents teach you how to do that?

• Do you remember when you first began doing that?

Which statement BEST describes swimming behavior in fish compared to humans?

• Swimming is neither an instinctive behavior nor a learned behavior but develops randomly or by chance in both organisms.

• Swimming is a learned behavior in both fish and humans because it is acquired as a result of a significant amount of practice in both organisms.

• Swimming is an instinctive behavior in fish because it is acquired genetically but is a learned behavior in humans because it requires practice to develop.

• Swimming is a learned behavior in fish because it requires practice to develop but is an instinctive behavior in humans because it is acquired genetically.

Some traits are inherited based on the genes from each parent, other traits are acquired as humans interact with their environment.

Which TWO statements are BEST supported by the information in the graphic?

• Our voice is only an inherited trait.

• Gaps in your teeth are an inherited trait, but it can be altered with braces.

• Parents can teach their offspring different things, and those are known as acquired traits.

• If a parent wants their offspring to be able to roll their tongue, it will be easy to teach because it is an inherited trait.

• Eye color is an acquired trait because all babies are born with blue eyes, and that changes based on the environment around them as their eyes develop.

Which describes how plants would MOST LIKELY be affected if all microorganisms disappeared?

• Flowering plants would no longer be able to reproduce without pollen.

• Plants would no longer die from diseases because all the bacteria would be gone.

• Green plants would no longer have a source of nutrients in the soil, once all the soil nutrients were consumed, they would begin to die.

• Green plants would no longer have a source of oxygen for photosynthesis, once all the oxygen in the soil was depleted the plants would begin to die.
