19
Q

Inorganic compounds

A

Anything that is not an organic compound is inorganic

20

Genes

A

Within some DNA molecules there are certain sequences of nucleotides called

22
Q

Trait

A

Coded genetic information leads to this

23
Q

Chromosome

A

Thousands of genes make up a single chromosome

24
Q

Nuclear change

A

Change in nuclei of its atoms

25
Q

Heat

A

The total kinetic energy of all moving atoms, ions, or molecules within a given substance

26
Q

Electromagnetic radiation

A

Energy travels in the form of wave as a result of changes in electrical and magnetic fields

27
Q

Energy quality

A

A measure of the capacity of a type of energy to do useful work

28
Q

High-quality energy

A

A great capacity to do useful work because it is concentrated

29
Q

Low quality energy

A

Is so dispersed that it has little capacity to do useful work

30
Q

First law of thermodynamics or law of conservation of energy

A

Whenever energy is converted from one form to another in a physical of chemical change, no energy is created or destroyed

31
Q

Second law of thermodynamics

A

Whenever energy is converted from one form to another, a lower quality energy is created

32
Q

System

A

A set of components that function and interact in some regular way

33
Q

Most systems have the following key components

A

Inputs from the environment, flows or throughputs of matter and energy within the system, and outputs to the environment

34
Q

Feedback

A

Systems are affected by this. It is any process that increases or decreases a change to a system

35
Q

Feed-back loop

A

Causes a system to change further in the same direction

36
Q

Negative or corrective feedback loop

A

Causes a system to change in the opposite direction from which it is moving

37
Q

Time delay

A

A lack of response during a period of time between the input of a feedback stimulus and the system’s response to it

38
Q

Tipping point

A

The point at which a fundamental shift in the behavior of a system occurs

39
Q

Synergistic interaction

A

When two or more processes interact so that the combined effect is greater than the sum of their separate effects

40
Q

Science

A

A human effort to discover how the physical world works by making observations and measurements, and carrying out experiments.
