Structure A is most likely a

• mitochondrion that synthesizes food for the cell

• nucleus that is the site of food storage

• mitochondrion that absorbs energy from the Sun

• nucleus that is responsible for the storage of information

Which statement best explains how A and B are able to survive in their environments?

• The organelles in B perform similar functions to the organ systems in A.

• The transport system in B is more complex than the transport system in A.

• Both A and B take in oxygen from the water.

• Only A can pass on traits to offspring.

Which structure produces chemicals that regulate the reproductive cycle?

• A

• B

• C

• D

The arrows represent the movement of which substances?

• carbon dioxide and sugar

• oxygen and ATP

• ATP and carbon dioxide

• oxygen and sugar

Which label correctly identifies what X represents in the concept map?

• nucleus

• chromosome

• autotrophic cell

• heterotrophic cell

The shape of each of the molecules is important because

• molecules having different shapes are always found in different organisms

• the shape of a molecule determines how it functions in chemical reactions

• the shape of a molecule determines the age of an organism

• if the shape of any molecule in an organism changes, the DNA in that organism will also change

Which process did the student record in his drawings?

• genetic engineering

• asexual reproduction

• selective breeding

• gamete formation

The bacteria that result from reproduction of this cell will most likely have the ability to

• replicate all of the genetic instructions found in humans

• produce vaccines to be used to immunize humans

• produce a human blood cell according to instructions in gene X

• produce the human protein coded for by gene X

If the line did not stay around the carrying capacity, but continued to rise, which concept would this graph best illustrate?

• environmental stability

• genetic variety

• behavioral change

• overproduction
