Breaking large molecules down into smaller molecules
digestion
Where does fertilization occur?
fallopian tubes
Who is the father of evolution?
Charles Darwin
What is a negative impact of the loss of biodiversity
Extinction, less stable ecosystems, potential loss of valuable resources
What is a benefit of sexual reproduction?
-diverse offspring
-can develop traits to aid in survival
The removal of all waste produced by the cells of the body
excretion
1. What is the female gamete?
2. What is the male gamete?
1. egg
2. sperm
Why does extinction occur?
The environment changes and the species cannot adapt
What is global warming and what causes it?
Greenhouse gases getting trapped in the atmosphere are causing Earth's temperatures to rise which had led to global warming

2. identical
Define the term photosynthesis
is the process of storing the energy from the sun in the chemical bonds of glucose (sugar). Occurs in the chloroplast of plant cells
What 2 things do the ovaries produce?
eggs and estrogen
The individuals best adapted to their environment will be more likely to survive. This allows their favorable characteristics to be passed onto offspring
ex. giraffes with longer necks
What is the negative impact of imported/invasive species?
They compete with natural species taking over food, space etc.
They disrupt the food web/ecosystem
List 2 advantages of asexual reproduction
- Enables organisms to reproduce without a mate
- No wasted time and energy
- Enables some organisms to rapidly reproduce a large number of uniform offspring
Define the term gel electrophoresis
A laboratory technique used to separate bands of DNA according to size
what reproductive technology process is used to create a visual map of chromosomes?
karyotype
A karyotype is an individual's complete set of chromosomes

2. DNA
3. Biochemistry (proteins)
4. Vestigial structures
5. Comparative anatomy (homologous structures)
6. embryology
List 2 negative effects of habitat destruction
species lose their habitat which results in loss of biodiversity, extinction, may affect food chain
What specific processes cause the variety of traits we see within organisms of a sexually reproducing species?
Meiosis
Crossing Over
Fertilization of sperm and egg
