Answer 9

A structural component of a cell

Question 10

Molecule

Answer 10

A chemical structure consisting of atoms

Question 11

Energy conversion

Answer 11

In transformations energy is lost as heat

Energy flows through an ecosystem, entering as light and exiting as heat

Enclosed by a membrane

Used D.N.A. as genetic information

Question 14

Eukaryotic cells (one of two main forms of cells)

Answer 14

Are divided into organelles; D.N.A. In nucleus

Question 15

Prokaryotic cells (one of two main forms of cells)

Answer 15

Lack organelles; D.N.A not separated in a nucleus

Question 16

Cells contain

Answer 16

D.N.A, heritable information that directs the cells activities

Question 17

D.N.A is the substance of

Answer 17

Genes

Question 18

Genes are the

Answer 18

Units of inheritance that transmit information from parents to offspring

Question 19

Feedback regulation in Biological systems

Answer 19

Regulatory systems ensure a dynamic balance in living systems

Chemical processes are catalyzed (accelerated) by enzymes

Many biological processes are self regulating: the product regulates the process itself
