Question 3

What is the scientific definition of Evidence?

Answer 3

The collected body of data from experiments and observations.

Question 4

What is the scientific definition of Inference?

Answer 4

An inference is a logical interpretation based on prior knowledge, experience or evidence.

Question 5

What is the scientific definition of of Variable? And what are the two kinds of variables?

Answer 5

A variable is a factor that changes in an experiment.

1. An independent variable is the variable being manipulated in the experiment.
2. A dependent variable is a variable responding to the manipulated variable.

Question 6

What is the scientific definition of a Hypothesis?

Answer 6

A hypothesis is a suggested answer to a well defined scientific question or a possible, testable explanation for observations.

Question 7

What is the scientific definition of an Experimental Group?

Answer 7

An experimental group is a group being manipulated in an experiment, including the independent variable.

Question 8

What is the scientific definition of Scientific Theory?

Answer 8

Question 9

What is the scientific definition of Abiogenesis?

Answer 9

Abiogenesis is the idea that long ago, very simple life forms spontaneously appeared through chemical reactions.

Question 10

What is the scientific definition of Scientific Law?

Question 15

What is the scientific definition of Anabolism?

Answer 15

Anabolism is the sum total of all processes in am organism that use energy and simple chemical building blocks to produce large chemicals and structures necessary for life.

Question 16

What is the scientific definition of Catabolism?

Answer 16

Catabolism is the sum total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks.

Question 17

What is the scientific definition of Photosynthesis?

Answer 17

Photosynthesis is the process by which green plants and some other organisms use the energy of sunlight and simple chemicals to make their own food.

Question 18

What is the scientific definition of an Omnivore?

Answer 18

An omnivore is an organism that eats both plants and other organisms.

Question 19

What is the scientific definition of an Autotroph?

Answer 19

An Autotroph is an organism that is able to make its own food.

Question 20

What is the scientific definition of Homeostasis?

Answer 20

Homeostasis is the maintenance of stable internal conditions.

Question 21

What is the scientific definition of a Herbivore?

Answer 21

A herbivore is an organism that only eats plants.

Question 22

What is the scientific definition of a Carnivore?

Answer 22

A carnivore is an organism that only eats organisms other than plants.

Question 23

What is the scientific definition of Heterotrophs?

Answer 23

Heterotrophs are organisms that depend on other organisms for food.

Question 24

What is the scientific definition of a Mutation?

Answer 24

A Mutation is an abrupt and marked change in the DNA of an organism compared to that of its parents.

Question 25

What is the scientific definition of Inheritance?

Answer 25

Inheritance is the process by which physical and biological characteristics are transmitted from the parent (or parents) to the offspring.

Question 26

What is the scientific definition of an Endotherm?

Answer 26

An Endotherm is an organism that is internally warmed by a heat-generating metabolic process.

Question 27

What is the scientific definition of an Ectotherm?

Answer 27

An Ectotherm is an organism that lacks an internal mechanism for regulating body heat.

Question 28

What is the scientific definition of Asexual Reproduction?

Answer 28

Asexual Reproduction is the process by which a single organism produces genetically identical offspring (offspring receives all DNA from one parent).

Question 29

What is the scientific definition of Receptors?

Answer 29

Receptors are special structures that allow living organisms to sense the conditions of their internal or external environment.

Question 30

What is the scientific definition of a Scanning Electron Microscope?

Answer 30

A microscope that passes a beam of electrons over the surface of a specimen.

Question 31

What is the scientific definition of Sexual Reproduction?

Answer 31

Process by which two parents produce genetically different offspring (offspring receives a combination of DNA from two parents).

Question 32

What is the scientific definition of the International System of Units?

Answer 32

The International System of Units is the metric system (abbreviated S.I.) which is the most widely used system of measurement in science.
