iChapter 1: Biology: Exploring Life
Characteristics of living things
1. Order- the highly ordered structure that typifies life
2. Reproduction- the ability of organisms to reproduce their own kind
3. Growth and Development- consistent growth and developme
The origin of species is the source of biological diversity
Speciation: the process by which one species splits into two or more species
- Each time it occurs the diversity of life increases
- Speciation from a common ancestor explains the diversity

UNIT 2: 5.9 Systems of Linear and Quadratic Equations Day 2
Using a separate sheet of paper, solve each system algebraically.
y = x 2 + 3x 5
y = x +3
y = x 2 36
y = x 16
y = 2x2 + 4x
y = x 4
y = x2 2 x + 2
y 2 x = 2
