Study Slideshow

What is an independent variable?

The factor in an experiment that the scientist changes.

5

The three particles that make up an atom are:

protons, neutrons, electrons

10

If an atom contains 3 protons, 4 neutrons, and 3 electrons, its mass number is..

7 (3 protons + 4 nuetrons)

10

Explain whether or not a monosaccharide is a macromolecule.

It is not, because it is a monomer, which is the subunit (smaller piece) of a polymer. Polymers are macromolecules.

20

Explain why there are so many different types of proteins, but only 20 amino acids, all with roughly the same structure.

The amount and order of amino acids in polypeptides varies.

20

What does an arrow represent in a food web?

Energy transfer

10

Which type of monomer is glucose?

carbohydrate--monosaccharide

10

Cellulose is a chain of glucose molecules hooked together. It stores energy in plants. Which type of macromolecule (polymer) is cellulose?

Polysaccharide (carbohydrate)

15

What is biology?

Study of life

5

What happens to an ecosystem when biodiversity increases?

It increases the ecosystem's stability, as more organisms fit into the complex food webs.

15

What is a concentration gradient?

Molecules have a higher concentration in one area compared to another.

15

Why isn't facilitated diffusion considered active transport?

It does not require energy, though it uses a protein carrier to move particles from a high to low concentration.

15

Compare the size of eukaryotic cells to the size of prokaryotic cells. Explain.

Eukaryotic cells are larger and more complex, as they have more specialized functions compared to prokaryotic cells.

10

What is an isotope--give an example.

An isotope is an atom with a different number of neutrons. C-13 is an isotope.

15

On a graph, where is the dependent variable?

Y axis

15

What is a reactant?

Substance that is used in a chemical reaction (input).
