• The gentle taper of the tail produces a logarithmic spiral
• one that gets smaller, yet the small parts look like large parts?

  Logarithmic spiral
• SHOWS WAVE- LIKE PATTERNS CREATED WHEN THE ANIMAL PRODUCES A BURST OF PIGMENT AND THEN LESS OF IT?

  Mollusk Shell
• ADD SUCCESSIVELY LARGER CHAMBERS TO KEEP UP WITH GROWTH?

  Nautilus Shell
• Bubbles intersect at three way junctions close to 120 degrees. AN INTERPLAY OF THE MATERIAL?

  SURFACE AREA AND TENSION
• When water meets a repellent surface. DROPLET SHAPE IS DICTATED BY?

  SURFACE TENSION
• ARISES FROM LAVA CRACKS THAT ARISE FROM BUILD UP AND TENSION?

  Regularity
• SINUOUS WAVES ARISE FROM A PULSE, AN EBB AND FLOW OF SAND AS THE WIND BLOWS?

  Sand dune undulations
• IS THE ARRANGEMENT OF LEAVES ON A PLANT STEM?

  Phyllotaxis
• WITH THE SUN AND RAIN FROM ABOVE, ORTHOGONAL (PERPENDICULAR) TO THE PLANE OF THE LEAF, THE DIVERGENCE ANGLE MUST BE SUCH AS TO MINIMIZE BLOCKAGE OF LOWER LEAVES BY HIGHER LEAVES?

  Fibonacci Spiral
• What are the cycles and patterns are seen in living systems?

  Biogeochemical, water, nitrogen, carbon
• influenza life cycle virus?

  Attachment, Penetration, Uncoating, Biosynthesis, Assembly, Release
• the basic unit of life?

  Cell
• smallest structure that exhibits almost all known

  properties/attributes of “being alive”
• reproduction and developmental processes depend?

  Mitosis and Meiosis
• one of the postulates of the Cell Theory, i.e. “Cells arise from

  the division of other pre-existing cells”.
• a four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids?

  tetrad
• Mitosis steps?

  Prophase, Metaphase, Anaphase, and Telophase
• Meiosis steps?


  PMAT 1 and PMAT 2
• In Mitosis, is that true that it has 4 stages in total plus the interphase?

  True
• Where mitosis happens?

  Somatic cells
• What is the purpose of mitosis?

  Cellular proliferation
• Mitosis produces how many daughter cell?

  2
• In mitosis, chromosome number remains the same
• In mitosis, Genetic variation doesn't change
• Mitosis and Meiosis produce new cells, similar basic steps, and starts with a single parent cell
• In meiosis, how many stages in total?

  8
• Meiosis happens in?

  Germ cells
• The purpose of meiosis is?

  sexual reproduction
• In meiosis, how many daughter cell it produces?

  4
• In meiosis, chromosome number is halved in each daughter cell
• In meiosis, Genetic variation increased
• The result of an extra copy of chromosome 21?

  Down syndrome
• Down syndrome is also known as?

  Trisomy 21
• haracteristic facial features, short stature; heart defects?

  Down syndrome
• susceptibility to respiratory disease, shorter lifespan?

  Down syndrome
• prone to developing early Alzheimer's and leukemia?

  Down syndrome
• often sexually underdeveloped and sterile, usually some degree of mental retardation?

  Down syndrome
• correlated with age of mother but can also be the result of nondisjunction of the father's chromosome 21
• correlated with age of mother but can also be the result of nondisjunction of the father's chromosome 21?

  Down syndrome
