Fundamental building block of all matter
- 2 Atoms = Molecule
- 3 Atoms = Compound
- Molecule is the smallest particle of a compound
- Atom is the smallest particle of a molecule
As association of 2 or more atoms. They are atoms joined in chemical bonds.
The smallest unif of life
Mitochondria…Structure within a cell that has a particular function to perform
Cells can be conbined to form tissues
A grouping of tissues engaged in a collective task
Set of organs engaged in a collective task that keeps thee body functioning properly. The circulatory system
Individual that consists of different type of cells.
Groupof single-celled or multi-celled individuals of the same species in a given area
All populations of all species in a specified area.
The physical environment… Living and non-living organisms. A community interacting with its environment.
All of the areas of the earth including the atmosphere that can support life. organisms live.
- Variation among living organisms
- A mass variety of life
Is the ability to maintain a certain level of things in the body. Tolerable ranges: Temperature, Sugar levels, PH (Level of acid)
Characteristics of Life
- Successfully reproduce
- Respond to changes in the environment
Makes its own food
Gets energy and nutrients from other organisms.
They break down organic material and recycling. Fungi and Bacteria. It can be recycled or re-used by plants
Blue-print of what an organism is – Contains the instructions to making protein.
The capacity to do work
Substance that an organism needs for growth and survival but cannot make for itself.
Parents produe offspring
- Deviced the classification system
- Deviced a naming system that has 2 parts
- Swedish botanist. 1750
- Did some things to helps us organize organisms
- Created a naming systems in order to help us label organisms
- Started with plants
- Binomial System: (Two – Names)
- 1st part: Genus (1st name)
- 2nd part: Species (Family Name)
1st letter of the Genus is always capitalized. Acer rubrum and done in italics.When you write it you just underline it.
Kids prefer candy over fresh green spinash
- Kingdom Animalia
- Phylum Chordata (with or without backbone)
- Class Mammalia (mammals
- Order Primates (Humans and monkeys)
- Family Hominidae (human like)
- Genu Homo
- Species Sapiens
- Eu = True
- Karya = Central point / Nucleus
Number of protons. Determines the element
- A pure substance that consists only of atoms with the same number of protons
Arranged the known elements by chemical properties. Atomic number. known for his extravagant hair.
Forms of an element that differ in the number of neutrons their atoms carry.
- Anything that has mass and takes up space
2 ideas about Evolution
- There is a variation within a species
- As environment changes nature selects the variant that is best suited to survive.
C.HOPKINS CaFé – Mighty Good especially with salt
- K (Potasium) Kalium
- Ca (Calcium)
- Fe (Iron) Feruso
- Mg (Magnesium)
- Na (Sodium) Natrium
- Cl (Chloride)
- Smaller than atoms
- Nucleaus = Protons and Neutrons
- Around = Electrons
Atomic Mass Unit
Number of protons find in the nucleaus
The number of protons
Total number of Protons and Neutrons
Forms of an element that differ in the number of neutrons their atoms carry
Why do some elements combine?
- Whether an element is chemical active or not depends on the number of Electrons on the outer energy level.
- Rule of 8
- When an atom is not consider neutral
- They have gained or loss electrons
- Ions form Ionic bonds
Organic compounds (Molecules)
- Nucleic acids (DNA / RNA)
Covalent Bond: STRONGEST BOND
- Carbon / Oxygen / Nitrogen / Phosphorus / Hydrogen / Sulfur
- Share Electrons
- Is formed when a positive side of a molecule is attracted to the negative side ofanother
- Hydrogen bonds are form when you have a combination of positive and negative sidesWater and protein attracts
Water has a pos and neg side
- Water loving molecules; substance
- Describes a substance that dissolves easily in water
- Water fearing molecules. Fats and Oils
- Resists dissolving in water.
- Liquid that can dissolve other substances
- The substance that is being dissolved
- Kool-Aid powder
- The combination of both substances
Attraction of water molecules to other substances
- Attraction of water molecules to each other
- Dueto hydrogen bonding
is a substance with an excess of Hydrogen ions
- A substance with an excess of Hydroxyl Ion.
Measure of molecular motion
Variant that it is best suited to survive
Protein Primary Structure
The order that the amino acid has to go in.
Protein Secondary Structure
The initial shape that the polypeptide takes as it is being constructed
Protein Tertiary structure
The final shape that the whole polypeptide has
found in animals and are solvents in room temperature.
found in plants and they tend to be liquids at room temperatures (or oils)
A long chain of amino acids
