Characteristics Of Life Quiz 1

Question 1

What is organization?

Answer 1

Organization is a sign of life when all living things are composed of molecules to organize to cells

EX} atoms to molecule to cells

Question 2

What is energy?

Answer 2

Living things need energy to function and survive. Energy can be stored for transferring and storing energy in the cell

Question 3

What is replication?

Answer 3

This is a goal of cells, cells replicate and arise from other cells

EX}DNA, GENES,HEREDITARY

Question 4

What are cells?

Answer 4

Cells make up an organism and are the most basic unit of life

Question 5

What is information?

Answer 5

Information is the process of organisms encoded and processed and passed on

Question 6

What is biology? Why is it important to study?

Answer 6

Biology is the study of life it is important to study because we obtain knowledge of life works and what is considered life

Question 7

What is a characteristic of life?

Answer 7

A characteristic of life is the continual maintenance of complex structure

Question 8

What is evolution?

Answer 8

Is a change in the characteristics of a population overtime.

Question 9

What is growth development?

Answer 9

It is something that defines life where organisms adapt evolve mature to survive.

Question 10

What is homeostasis?

Answer 10

Stable chemical and physical conditions in an organism’s cells, tissues, and organs

Can be achieved by: matching conditions of a stable external environment or by active physiological processes

Question 11

What is the response to environment?

Answer 11

Adaptation

Question 12

What is an organism?

Answer 12

Any living entity that contains one or more cells

characteristics are as follows: having organization, energy, replication, growth and development, information, evolution, homeostasis, cells.

Question 13

Why is the cell the smallest unit of life?

Answer 13

The cell is the smallest unit of life because it is the most fundamental building block of every living organism.

Question 14

What is a prokaryote?

Answer 14

A organism lacking a nucleus and containing relatively few organelles or cytoskeleton components

Question 15

What is a eukaryote?

Answer 15

An organisms whose cells contain a nucleus, numerous membrane organelles and extensive cytoskeleton

Question 16

What is adenosine triphosphate?

Answer 16

When hydrolyzed USED TO STORE AND TRANSFER CHEMICAL ENERGY

MOLECULE consisting up of an adenine base, a sugar, and 3 phosphate groups that have high potential energy (ATP)

Question 17

How is energy important to life?

Answer 17

Energy helps cells/life to stay alive, grow, and reproduce

Question 18

What is metabolism?

Answer 18

Balance of catabolic and anabolic reactions

Is the activity where cells acquire and use energy as they make and break apart organic compounds

Question 19

What is anabolism?

Answer 19

Process of chemical receptions that build larger molecules out of smaller molecules and atoms

SMALL to LARGE

Question 20

What is catabolism?

Answer 20

process that breaks larger molecules into smaller ones

requires an input of energy

LARGE TO SMALL

Question 21

What is the theory of evolution what does it state?

Answer 21

1. Most organisms can produce numerous offspring, but environmental factors limit the number that actually survive and reproduce.
2. heritable variations allow some individuals to compete more successfully than others for food, mates, and space
3. Successful individuals pass the favorable characteristics to offsprings
4. Favorable traits become more common in next generation and less successful become uncommon
5. Process of natural selection result in evolutionary change
6. Include genetic flow, mutations, genetic drift

Question 22

What is DNA?

Answer 22

DNA molecules contain instructions for making a new organism

Blue print of life

Question 23

What is the cell theory?

Answer 23

-most basic unit of life

• all living things one made up of one or more cells
• cells can only come from other cells-

Question 24

How is the cell theory and the theory of evolution related?

(Relationship between the cell and common ancestry)

Answer 24

Together cell theory and the try of evolution unity in belief that:

  1. The cell is the fundamental structural unit in all organisms

   2. All species are related by common ancestry and have changed through time       in response to natural selection

Question 25

Why is the cell important to biology?

Answer 25

It is important because it is the basic structural unit of living organisms
