Question 1

What are organisms?

Answer 1

Anything that is alive.

Question 2

Define homeostasis.

Answer 2

It is keeping the internal enviroment of the cell, within the ranges required for life.

Question 3

Answer 3

Its the material inside of all cells that organells float in.

Question 4

What is a zygote?

Answer 4

Its an egg that is fertilized.

Question 5

Define metabolism.

Answer 5

Its the sum of all the chemical reactions in an organism.

Question 6

What is cellure respiration?

Answer 6

Its the metabolic process that releases the chemical energy stored in food.

Question 7

What are the 3 nonliving levels into which life is organized?

Answer 7

They are atoms, molecules, and organells.

Question 8

At what level of organization does life begin?

Answer 8

At the cellular level.

Question 9

What do cells orgainize into?

Answer 9

They orgainize into tissues.

Question 10

What is a hypothesis?

Answer 10

A hypothesis is an inference that you make before an experiment.

Question 11

What is the control group?

Answer 11

This is the group that didn’t change in the experiment; the group being compared to.

Question 12

What is the dependent variable?

Answer 12

This is the variable that changes because the independent variable changes.

Question 13

What is the independent variable?

Answer 13

This is the variable that you change in the experiment, it varies the dependent variable.

Question 14

What do tissues organize into?

Answer 14

Hey organize into organs.

Question 15

What do organs form together?

Answer 15

They form systems.

Question 16

What do many systems form into?

Answer 16

They form into an entire organism.

Question 17

What is biology?

Answer 17

It is the study of all living things.

Question 18

What are organelles?

Answer 18

They are a part of a cell, each does a specific job.

Question 19

What are cells?

Answer 19

They are a part of a tissue, all cells are seperate into different categories (ie, brain cells).

Question 20

What is scientific method?

Answer 20

It is the process that people go through in order to form a hypothesis, create a theory, and through experimentation, possibly form a scientific fact.

Question 21

Define observation?

Answer 21

This is the act of watching something, to see how it acts, or its effects on the enviroment, or a specific subject.

Question 22

What is the experiment group?

Answer 22

This is the group that is directly manipulated in order to test or see the results of a hypothesis or theory.

Question 23

What is theory?

Answer 23

This is an educated guess/observation, just before scientific fact.

Question 24

What is a prediction?

Answer 24

In science this is a guess that holds slightly less merit than a hypothesis, solely because it is an inference made without further education into the subject in question (an uneducated guess).

Question 25

What is an experiment?

Answer 25

These are the steps taken to test a hypothesis or theory. It is important that when performed, only a single given variable is changed at a time.

Question 26

What is development?

Answer 26

It is the stage in life where the organism grows into the later stages of its life.

Question 27

What is organization?

Answer 27

In biology, organization is the separate levels of life in an organism (ie, cells, tissue, organs, organ systems, etc).

Question 28

What is unicellure?

Answer 28

It is an organism consisting of only a single cell, such as a bacterium.

Question 29

What is multicellular?

Answer 29

It is an organism consisting of many cells, such as a human.

Question 30

Define evolution.

Answer 30

This is the process in which a species adapts to its enviroment over a long period of time.

Question 31

Define adaptation.

Answer 31

This is similar to evolution, except that it is more short term, where an organism quickly "evolves" in a new environment that it may have, for example, immigrated to.

Question 32

What is natural selection?

Answer 32

It is the process (or possibly belief) that an organism will naturally be attracted to a mate that has a greater chance of producing healthier offspring.

Question 33

What is reproduction?

Answer 33

This is the process in which two members of the same species conduct in either sexual or asexual activities in order to form one or more new members for the population of its species.
