Basic Principles Of Biology

Question 1

Cell theory

Answer 1

Basic unit of life (all living organisms are composed of cells)

Question 2

Gene Theory:

Answer 2

traits are inherited through gene
transmission. Genes are located on chromosomes and
consist of DNA.

Question 3

Evolution:

Answer 3

any genetic change in a population that is
inherited over several generations. (Noticeable or not
noticeable)

Question 4

Homeostasis:

Answer 4

ability to maintain a constant internal
environment in response to environmental changes.

• the cells function best when they are in balance
• the body regulates the levels of things like témperature and acidity

Question 5

Thermodynamics:

Answer 5

Energy cannot be created or destroyed,
only transferred and transformed. Cells absorb energy and
convert it into different forms.

37°C is the perfect temperature for out enzymes to function
• receptors like our skin send signals to the brain through the nervous system and our effectors preform the action the bfain send back (ex. Shivering to preserve heat)

Question 6

DNA

Answer 6

Is the chemical that all of our genetic material is made of

Question 7

Gene

Answer 7

A small section of DNA that codes for protein

Question 8

Genome

Answer 8

Is an entire set of genetic material in an organism

Question 11

Chromosomes

Answer 11

Are made of dna

Question 13

What are the three main principles of cell theory

Answer 13

These principles are: cells are the basic unit of life, all living things are made up of cells, and all cells come from other cells.
