A student was reading about the gases in air. Ozone helps protect Earth from harmful ultraviolet rays that come from the sun. Certain types of pollution created by humans have caused a hole in the ozone layer. This hole is over the South Pole and could become larger if this type of pollution increases.

What elements are present in the molecule?

What is the color of the molecule?

What is the shape of the molecule?

How many atoms are present in the molecule?

The diagram represents a cellular process used by cells. In which situation would this process be beneﬁcial to the cells?

growth and repair, because it produces identical types of cells

growth and repair, because it makes the cells of the organism larger

reproduction, because it creates more energy for the organism

reproduction, because it increases the number of chromosomes in the cells

The table shows the estimated percent concentrations of atmospheric gases. Trace gases are composed of small amounts of gases such as carbon dioxide, water vapor, and methane. Which of these will most likely increase the amount of a trace gas in the atmosphere?

A company reﬁning uranium ore is powered by natural gas.

A pine cone releases the protected seeds inside after it is exposed to intense heat.

A hydroelectric dam increases the amount of water processed into energy after a ﬂood.

A bacterium releases oxygen gas during photosynthesis.

A partial food web shows the movement of matter and energy in a land ecosystem. Deer need producers and oxygen to provide energy and matter for their cells. What is the primary source of oxygen for the deer in this ecosystem?

The oxygen is a product of photosynthesis by the grasses.

The oxygen is a product of photosynthesis by the insects.

The oxygen is a product of cellular respiration by the cougar.

A student has been learning about atoms. He wrote a small paragraph describing one. The student describes particles on the edge of the atom. Which statement supports the student’s claim that the particles on the edge of the atom do not move away from the center?

The particles are attracted to the center because they have a charge opposite to the center’s charge.

The particles are connected to the center by an object similar to a rope.

The particles are held in place because atoms are a solid structure.

The particles are pushed toward the center by the nuclear charges of other atoms.

A person riding a bicycle wants to move the bicycle forward. She moves her legs up and down on the bicycle’s pedals. Then the rider wants to stop the bicycle. She stops pedaling and the bicycle slows. She takes one of her feet off a pedal and puts her foot on the ground to stop the bicycle and stay upright. Which of these best identiﬁes a pathway of systems in the rider’s body, as described in this scenario?

nervous system → musculoskeletal system → nervous system → musculoskeletal system

nervous system → musculoskeletal system → circulatory system → nervous system

musculoskeletal system → nervous system → circulatory system → musculoskeletal system

musculoskeletal system → circulatory system → musculoskeletal system → nervous system

A student uses a microscope to observe a singlecelled organism that can move. The organism contains a nucleus and many chloroplasts. Based on the observations, the student claims the organism is not a bacterium. Which observation best supports the student’s claim?

The organism performs photosynthesis.

When an athlete began running, both her breathing and heart rates increased. The athlete's breathing and heart rates increased as she was running because the athlete needed to

transport more oxygenated blood to her muscles

exhale more oxygen from her lungs

decrease the temperature of her skin

increase the amount of carbon dioxide in her blood

The diagram represents solar panels collecting energy from sunlight and then converting that energy to electrical energy. The electrical energy can be stored as chemical energy in batteries. Then, this chemical energy can be converted back to electrical energy to power lights and appliances. Which of these best describes a similarity between photosynthesis and the changes in energy represented by the diagram?

During photosynthesis, a plant’s leaves change solar energy into chemical energy, and then the chemical energy is used for the plant’s life functions.

During photosynthesis, a plant’s roots absorb and store water until the plant needs the energy stored in the water for the plant’s life functions.

During photosynthesis, a plant’s leaves change chemical energy into solar energy, and then the solar energy is used for the plant’s life functions.

During photosynthesis, a plant’s roots absorb water and then transform the water into chemical energy that is used for the plant’s life functions.

Students were looking at coins during lunch. One of them noticed that older pennies looked and felt different from new pennies. The students decided to investigate whether all pennies are made of the same materials. The students measured the mass and the volume of 10 pennies and then divided the mass by the volume to determine the density. The measurements were recorded in a data table. The teacher told the students that newer pennies contain copper and zinc. Copper has a density of 8.96 g /cm3. Zinc has a density of 7.1 g / cm. Which statement is best supported by the data and information from the teacher?

Pennies 6 through 10 are mostly copper because their density is closer to copper’s density.

All pennies have the same amount of copper since their volume is the same.

Pennies 1 through 5 are mostly copper because the mass of copper is less than the mass of zinc.

Which cellular process converts light energy from the sun into chemical energy that organisms use for life functions?

photosynthesis, in which carbon dioxide is used and sugars are produced

digestion, in which starch is broken down into simple sugars

respiration, in which oxygen is used and carbon dioxide is given off

fermentation, in which sugar is broken down and alcohol is given off

A diagram of a plant cell is shown. The function of the plant cell structure shown in the enlargement is to —

use energy from sunlight to make sugar

direct all the cell’s activities

regulate substances that enter and exit the cell

Which statement does not describe a possible function of chromosomes?

They provide a cell with energy.

They regulate the proteins in a cell.

They determine the gender of an individual.

They inﬂuence the traits of the entire organism.

Use the diagrams of an animal cell and a plant cell to answer the question. Features of plant cells that clearly make them different from animal cells are

a rigid cell wall and chloroplasts.

a larger nucleus and fewer chromosomes.

more cytoplasm and smaller vacuoles

a changing size and indeﬁnite shape.
