What is the function of a cell wall?

to protect and support the cell

to perform different functions in each cell

to prevent water from passing through it

to prevent oxygen from entering the cell

These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.

Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.

Which statement best explains why animals are considered heterotrophic?

They are able to obtain nutrients by consuming other organisms or their products.

They are able to produce food through the process of photosynthesis.

They are able to produce food through the process of respiration.

They are able to obtain nutrients by decomposing plant and animal tissue.

Which word equation best represents the process of cellular respiration?

glucose + oxygen ---> carbon dioxide + water

carbon dioxide + glucose --> oxygen + water

carbon dioxide + water --> glucose + oxygen

oxygen + water ---> carbon dioxide + glucose

Which best explains why the rate of a biochemical reaction decreases at high temperatures?

The shape of the enzyme changes.

The activation energy increases.

The enzyme-substrate complex forms.

The bonds between substrates are broken.

Enzymes are proteins that help increase the rate of chemical reactions inside cells. These proteins are composed of many simpler molecules called amino acids. Which of the following suggests that the shape of an enzyme determines the enzyme’s function?

Enzymes are specific to a substrate

Enzymes can operate in a wide range of conditions.

Enzymes are activated by neighboring molecules.

Enzymes can be found in all life-forms.

What would the INDEPENDENT variable be in an experiment testing which types of paper airplane goes the furthest?

the height of the plane's flight path

the distance of each plane's flight

the flight pattern of each plane when thrown

Do not have a nucleus and organelles

Make up only single celled organisms

Cell theory states that

Organisms are the basic unit of life

Both cells and organisms are the basic units of life

The questions of the basic unit of life are too abstract to answer

Which is true of prokaryotic and eukaryotic cells?

Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles.

Prokaryotic cells are larger than eukaryotic cells.

Eukaryotic cells do not have nucleus , and prokaryotic cells do have nuclei.

Eukaryotic cells are simpler than prokaryotic cells.

What do all of these organisms have in common?

They all have uniform offspring

They have the same internal and external structures

The levels of organization from the simplest to the most complex are

Cells, tissues, organs, organ systems, organism

Organisms, organs, tissues, cells, organ systems

Cells, organs, organ systems, tissues, organism

Tissues, cells, organs, organism

the concentration levels are different

If a cell is 30% salt and the solution the cell is in is 10% salt ...

water will move out of the cell.

If an organism is found to have ribosomes, this organism ...

could be prokaryotic or eukaryotic.

What is the purpose of an enzyme?

give permission for the reaction

control how many reactions occur

What happens when enzymes are heated to a high temperature?

The shapes of the enzyme are altered denature

The enzymes' amino acid sequence changes.
