Term
Bottleneck
Definition
Occurs when asmall percentage of a population survives, less variability
Term
Adaptive Radiation
Definition
Refers to the fact that a speciation occurs through adapting to an envionrment through natural selection
Term
Genetic Drift
Definition
Easily observable in small populations, a change in the frequency of an allele
Term
Founder's Effect
Definition

 

  1. When a small population breaks away from a large one
  2. Reduction in allele diversity greater expression of genetic traits than would be in big one

 

Term
Abiotic Sythensis
Definition

 

  1. Theory that life originated from inorganic matter
  2. 1953 Stanford, was able to get amino acids from inorganic molecules and lightning

 

Term
Endosymbiotic Theory
Definition

 

  1. Belief that eukaryotes (cells with nuclei) developed from prokarytoic cells (without nuclei)
  2. Chlropoasts in planet cells and mitochondria developed from the smaller ones

 

Term
Origin of Life on Earth
Definition

 

  1. One theory is that life developed from non-living material when nonliving synthesis took place and amino acids and nucleotides formed
  2. Believe RNA is first genetic material

 

Term
Five Kingdom Classification
Definition

King Phillip came Over for Good Soup

Kingdom Phylum Class Order Family Genus Species

Term
Five Kingdoms
Definition

Monera (Prokaryotes)

Protista (Algae)

Fungi

Plantae

Animalia

Term
Types of Protista
Definition

Photosythetic (Plants)

Consumer (other organisms)

Saprophytes (dead things)

Term
Fungi Kingdom
Definition

Cell walls have chitin, a long chain polymer carb

 

Term
How did Oxygen appear in atmosphere
Definition

Paleoproterozoic Era (2.5-1.6 billion years ago)

 

Oxygen in ocean combined iwth iron, then started to leak out. Led to extinction of many anaerobic organisms

Term
Vascular Plant
Definition
Tall growing plants, have xylem and phloem are vascular
Term
Nonvascular Plants
Definition
Do no have xylem to transport water, these are mosses and liverworts
Term
Autotrophs
Definition
Make their own food
Term
3 major processes of plants
Definition
photosynthesis, transpiration, and respiration
Term
Two Major Systems of Plants
Definition

Shoot System: Leaves, buds, stems, flowers, and fruits
Root System: Component of the planat that is underground.

 

Meristems form plant cells by mitosis

Term
Plant Transpiration
Definition
Light encourages stomata to open and water is lost more quickly than in dark. If high temp, high transpiration.
Term
Plant Alternation of Generations
Definition

Two processes during sexual reproduction alternate.

Meosis and fertilization

Term
Equation for Cell Respiration
Definition

 

 

C6H1206 + 6O2 -> 6CO2 + 6H20 Energy

Term
11 Organ System
Definition
Skeletal, Muscular, Nervous, Digestive, Respitory, Circulatory, Skin, Excetory, Immune, Endocrine, Reproductive
Term
Skeletal System
Definition
Support throughout the body and allows structure
Term
Muscular System
Definition
Allows the body to move
Term
Nervous System
Definition

 

  1. Brain, spinal cord, and nerves
  2. Responses, electrochemical
  3. Involuntary things like heartbeat

 

Term
Digestive System
Definition
Mouth, pharynx, esophagus, stomach, rectum, anal, canal, teeth, tongue, liver, appendix
Term
Respitory System
Definition
Nose, trachea, bronchi, lungs
Term
Circulatory
Definition
Heart, blood, and blood vessels
Term
Skin
Definition
Skin, hairn, nails, sweat glands, oil glands
Term
Excetory
Definition

 

  1. Kidney, uters, bladder, urethra
    1. Maintin amount of fluid in body
    2. Removes solid waste

 

Term
Immune
Definition

 

  1. Lymph Nodes, lymph vessels, spleen
    1. Protects from external intruisions
    2. Protect against some cancer cells

 

Term
Endocrine
Definition

 

  1. Pituitary gland, pineal gland, thyroid gland
  2. Stimulate heart muscle
  3. Regulate blood sugar

 

Term
Reproductive
Definition
Testes, uretrhra, prostate, scrotm vagina etc.
