• Cellular Level
•Cells -a group of atoms, molecules, and organelles working together;
Basic unit of life
• Tissue Level
•A tissue -a group of similar cells working together.
• Organ Level
•An organ -a group of different tissues working together
• Organ System Level
•An organ system is a group of organs working together
•Humans have 11 organ systems.
• The Organism Level
•A human is an organism

Question 2

What are the elements and macromolecule types (5) and functions (4) on the chemical level?

Answer 2

Question 3

What is tissue def and the 4 types of primary types of tissue?

• Four types of primary tissues are
1. Epithelial tissue
2. Connective tissue
3. Muscle tissue
4. Neural tissue

Question 4

what are the 2 classifications of organ types and make-up requirements?

Answer 4

1. Multi-taskers (skeletal muscles- for movement thermal regulation etc)
2. Specialists (Heart etc)
   They are made up of different tissues and organ functions are supplied by their tissues wether movement is required, joining or anchoring is needed, sending message to do things and or a cover or a way to let things in etc.

Question 5
