• The vagina is also known as the birth canal
• The uterus is a hollow, fist-sized organ located between the bladder and scrotum
• Motor neurons carry messages away from the brain
• Cerebrum activity and thought
• Cerebellum under the cerebrum posture, balanced
• Brain stem automatic functions breathing,blood pressure
• The spinal cord serves as a channel for signals between the brain
• Peripheral nervous system runs through out the heads, neck and body
• Somatic nervous system associated with involuntary
• Spinal nerves carry a motor and sensory signal
• Cranial nerves that's carry information into the brain stem
• The two major divisions is Central nervous and peripheral nervous system
• The two central nervous system has Spinal cord and brain
• The two peripheral system is autonomic ns and somatic ns
• The two automatic ns and peripheral ns is sympathetic ns and parasympathetic ns
• Nucleic acid


  Carrying molecule
• DNA - INSTRUCT NEED BY ORGAN
• RNA- DIRECTLY INVOLVED IN PROTEIN
• RNA - SINGLE STRAND
• DNA - DOUBLE STRAND
• Nucleotide - BUILDING ROCK OF PROTEIN
• DELETION - deleting
• DUPLICATION - EXTRA OR COPY
• INVERSION - FLIPPED
• TRANSLOCATION - TRANSFER TO ANOTHER CHROMOSOME
• Imprint -are shallow external molds
• Compression -preserved sedimentary rock
• Comparative anatomy ( homologous structures ) -different function but same origin
• Analogous structures - without share or involved independently
• Embryo development - evidence that the species are related
• GENETIC INFORMATION - dna genetic code reflect
• Jean pabtiste de lamark - who the first evolution who believe that the organism can change
• ADAPTION -ability of the organism
• What is the three adoption

  Theory of need,theory of use and diuse,theory of acquired characteristics
