Whatis Biology? |
Scientific study of life. |
|
What are the characteristics of living organisms? |
-Life is Organized -Need energy -Respond to Stimuli -Reproduce -Evolution & Adaptation -Homeostasis and regulation |
|
What is the core principle of Biology and why? |
Evolution because it explains the unity and
diversity if life. |
|
Can you list the levels of organization from the smallest to the largest? |
Atom Molecule Cell Tissue Organ Organ System Organism Population Community Ecosystem Biosphere |
|
Explain what happens to chemicals(materials) and what happens to energy in an ecosystem. |
Energy is the ability to do work energy is burned when cells use nutrient molecules to make their parts and products, they carry out a sequence of chemical reactions |
|
What is the mechanism of evolution? |
it occurs by natural selection. if your environment is good you will survive and reproduce. e.g frog; drought happens, it turns brown |
|
Explain the process of natural selection. |
if you can adapt and survive, you reproduce. e.g. birds |
|

observation
hypothesis experiment conclusion |
|
•What are the steps of the scientific method? |
1. observation 2. hypothesis 3. experiment/test 4. data 5. conclusion |
|
•What is necessary for a hypothesis to be valid? |
observation and that it can be tested |
|
•What is necessary for a good experiment that is valid? |

|
•What is a peer reviewed study? |
closely examined by a panel of reviewers who are experts on the topic |
|
•How is a “theory” in science different from a “theory” in everyday language? |
theory in science: is supported by a lot ofevidence. theory in language: speculation |
|
What is a cell? |
-the smallest most basic unit of life. -although alive it is made up of nonliving molecules |
|
metabolism |
the chemical reaction that occurs in a cell during growth and repair |
|
homeostasis |
self regulating mechanism; hypothalamus
|
|
evolution |
the process by which different kinds of living organisms are thought to have developed |
|
taxonomy |
identifying, describing, and naming organisms |
|
What are the three domains of life? |
1. Archaea 2. Bacteria 3. Eukarya |
|
What are the 4 kingdoms under Eukaryotes? |
1. Protista 2. Fungi 3. Plantae 4. Animalia |
