What is life?
How we fit into the big picture
What are the nine charatertics of life?
Order, Metabolism, movement or motility, responsivness, cold, reproduction, growth and development, inhertiance of traits, adaptation, and evoloution.
Only maintained by using energy. Maintained by an arrangment of structure units and activties.
Order
Total of chemical processes or reactions in living organisms. Sum off all life’s processes
Metabolism
Move themselves, to move parts of their body
Movement or motility
Example of Movement or motility in animals
birds fly, plants open the flowers
The ability of organisms to precede and react to their enviroments
Responsivness
Example of responsivness in animals
Humans percieve weather put on coat, Birds fly low when you perchieve storms, and animals get winter coat/lose winter coat.
Process that gives rise to offspring, allows life to continue
Reproduction
Two types of reproduction
Sexual, asexual
Describe asexual reproduction
one parent, identical gene information, bacteria, plants
Describe sexual reproduction
two parents, half of genes
Why is a sleep clone not really cloning?
the cell has been changes, it can be reverted back to the orginial cell.
Ordered sequence of progressive changes that result in increased size and complexity
Growth and Development
Heriety, Inherit genes from parents
Inheritance of traits
Overtime, something happens (physical traits, changes in body) They can surive.
Adaptation
Aquires new ways to surive Passed on through the generations, they can aquire traits over time and it becomes the norm.
Evoloution
What is natural selection?
Over the course of evolution nature selects the stronger species to reproduce and surive.
What is maninduced artificial selection?
We intefere with nature. Examples: shaving wool on sheep, breeding dogs.
What is how to organize organisms
Classification system
What are the 5 kingdoms
Monera, Protists, Fungi, Plants and Animals
What is divided to make the 6th kingdom?
Monera
What are the two divisons of monera, to the make the 6 kingdoms
Archae bacteria, Eubacteria
Name of the steps of the scientific method?
- Make an obersavation, 2. Ask a question. 3. Make an educated guess or hyopthesis. 4. Design an experiment with a control. 5. Gather your data (what is it telling you)
What do you do if your hypothesis is wrong
Redesgin the experiment
What do you do if your hypothesis is right?
Share your information
What occupies space, and is everywhere
Matter
Study of structure and behavior of atoms and molecules
Chemistry
Can not be broken down further
Element
6 elements that make up living organisms (SPONCH)
Sulfur,phosphorous, oxygen, nitrogen, carbon, hydrogen.
Name three types of bonds
Covalent, ionic, and hydrogen
2 or more atoms bonded together (held by chemical bonds) Resulted by electrons
Molecule
Causes chemical reactions to happen
Electrons
Strongest, share electrons energy of two atoms.
Covalent Bond
What results from a covalent bond?
Water molecule
Weakest bond, most important in nature
Hydrogen Bond
What results from a hydrogen bond
Water
Cystalized structure, two atoms oppositely charged
Ionic bond
What results from an ionic bond?
Table salt
What is important to life?
Water
What are 4 reasons why water is important?
- Water makes up a bulk organisms
- Water acts as nature’s cooling system
- Universal Solvent
- Because of water and photosynthesis we have oxygen in our air.
Why is water the universal solvent
any substance can dissolve into it
What is solute?
substance dissolved (sugar, salt)
Three electronic properties of water
- Cohesion. 2. Adhesion, 3. Capiliarity
Physical Property of water
Surface tenison
Tendecy of like molecules to cling together
Cohesion
