SCIENCE

• G0 Phase


  quisent or resting stage
• first gap phase (G1)


  cell becomes metabolically active in preperation for DNA replication
• synthesis phase 


  DNA content of the cell is duplicated and may last 6-8 hours
• second gap phase (G2)

  cell continues to growth, synthesizes proteins and enymes need for cell division, and completes the replication of its centuosome's for admit 4-5 hours
• mitosis phase (M)


  cell divides into the daughter cells equal DNA content and is the shortest phase up to 2 hours
• interphase


  the period G1, 5, and G2 are together
• cyclin 


  dependent kinases (CDK) asnd cyclins control molecules which serves as checkpoint between phases
• DNA


  this is where the cell comes from
• cell 


  basic unit of life
• DNA 


  deoxyribonucleic acid-genetic information
• bone marrows 


  produces the cell through mitosis
• Gametes


  sex cells
• egg cell 


  female cells
• sperm cells


  male cells
• mitosis


  the cell division into two daughter cells
• early prophase (metasis phase)


  the forming of chromosomes
• metaphase (mitosis phase)

  the alignment of the chromosomes in the equatorial division
• anaphase


  separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
• telophase


  the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
• later prophase 


  attachment of microtube to the kinetochore
• Gregor Johann Mendel


  father of genetics
• seven characteristics that george observed:

  height

  pod shape

  pod color

  seed shape

  seed color

  flower color

  flower position
• allele 


  variability of a specific gene
• heterozygous


  combination of different allele
• species 


  group of organism that can interbreed and produce healthy and fertile offspring
• taxonomic hierarchy

  kingdom

  phylum

  class

  order

  family

  genius

  species
• gametophyte (non-vascular phase)


  haploid social phase
• sporophyte (non-vascular phase)


  diploid phase
• phloem 


  transports sugar from leaves to other parts of the plant
• animal taxonomy 


  have 9 major phyla of animals
• porifera


  are asymmetric aquatic animals with unspecialized cells
• echinoderms


  are radially asymmetric marine animals with up to 7000 species that include sea cucumbers, starfish, etc
• Digestive System

  Circulatory System distributes absorbed nutrients and carries hormonal signals that control digestion speed
• Digestive System

  Endocrine System produces hormones that regulate digestion
• Digestive System

  Excretory System works with to eliminate waste
• Digestive System

  Nervous System controls the speed of digestive processes
• Digestive System

  Muscular System assists with the movement of food through the digestive tract
• Carbohydrates


  A large group of organic compounds that includes sugars, starch, and cellulose, containing hydrogen and oxygen in the same ratio as water (2:1) and used as structural materials and for energy storage within living tissues
• proteins- help in growth
• fats- provide energy
