In the 1600s, advances in microscopy led to the development of cell theory. Which of the following statements is part of the cell theory?

All cells require water and oxygen to survive.

All living things are made of one or more cells.

All cells have organelles with specialized functions.

All living things rely on several different types of cells.

A scientist analyzing an unknown substance has determined that it consists of carbon, hydrogen and oxygen. During experimentation, she determines that the substance is soluble in oil but not in water. Which of the following macromolecules is the unknown substance most likely to be?

Carbohydrate

Nucleic acid

Lipid

Protein

A single-celled organism is represented in the diagram below. An activity is indicated by the arrow. If this activity requires the use of energy, which substance would be the source of this energy?

DNA

a hormone

ATP

an antibody

A carbohydrate is an organic compound that is composed of carbon, hydrogen, and oxygen. The unique structure of carbohydrates makes them useful material for building cell walls in plants. Which of the following is a function of carbohydrates in animals?

digesting food

fighting disease

storing short-term energy

transmitting nerve impulses

In a cell, information that controls the production of proteins must pass from the nucleus to the

cell membrane

mitochondria

ribosomes

chloroplasts

Sometimes scientists must make assumptions about their subject of study because some aspect of it cannot be tested directly. In cases like this, scientists assume that the natural world operates in a consistent fashion. Which of the following would be the best example of a case in which scientists would have to make an assumption based on present experience?

assuming that modern DNA is composed of the same nucleotide bases that made up DNA 1,000 years ago

assuming that rainfall patterns in the northern United States are similar to rainfall patterns there 50 years ago

assuming that trees in Brazil use the chlorophyll in their leaves for photosynthesis in the same way trees in Florida do

assuming that the feathers on a dinosaur skeleton were used for flight and insulation as they are in modern birds

Which equation best describes a method of anaerobic respiration?

Glucose yields energy and lactic acid.

Glucose and oxygen yield lactic acid and water.

Glucose and lactic acid yield energy and carbon dioxide.

Glucose and oxygen yield energy, carbon dioxide, and water.

Which organelle is correctly paired with its specific function?

cell membrane—storage of hereditary information

chloroplast—transport of materials

ribosome—synthesis of proteins

vacuole—production of ATP

If a scientist discovers a new synthetic chemical that appears to have many potential uses, why must society be extremely cautious after the new chemical is manufactured?

The scientist's work may be flawed, and his work must be verified.

The chemical may be too expensive to manufacture for the general population.

Harmful problems for individuals and the environment may not be initially known.

The best use may not be immediately obvious, and the chemical may be wasted.

10.

Which reactants of aerobic cellular respiration are the byproducts of photosynthesis?

glucose and water

oxygen and glucose

carbon dioxide and water

oxygen and carbon dioxide

11.

When the oxygen atom in one water molecule is close to a hydrogen atom in another water molecule, what is most likely to happen?

The water molecules will draw toward each other.

The two water molecules will form a larger molecule.

The like charges of the water molecules will repel each other.

The two water molecules will gain energy and vaporize, becoming water vapor.
