What evidence might you use to support that these
might have a common ancestor?
  • bilateral symmetry
  • body segmentation
  • endoskeleton (bony or cartilaginous)
  • pharyngeal pouches (ears) (present during some
    stage of development)
  • complete digestive system
  • ventral heart
  • closed blood system
  • tail (at some stage of development)
  • Chordates (Chordata)
  • Vertebrates-fish, amphibians, reptiles, birds,
    and mammals.
  • Four characteristics
  • Stiff dorsal rod helps to organize the embryos
    development.
  • The central nervous system (brain and spinal
    cord) is tubular
  • Their sides have slits just behind the head.
    These pharyngeal slits (pharynx means throat)
    becomes gill slits of adult fish. In
    air-breathing chordates, they develop into
    various organs such as internal parts of the ears
  • They have a tail in humans its the tailbone, or
    coccyx, which curls internally.

Human Elephant Moose
Kingdom Animalia Animalia Animalia
Phylum Chordata Chordata Chordata
Class Mammalia Mammalia Mammalia
Order Primate Proboscidea Artiodactyla
Family Homindae Elephantidae Cervidae

Which of the following matches a cell organelle
with its function? A. chloroplastmovement B.
nucleuscell regulation C. vacuoleenergy
production D. mitochondrionphotosynthesis
Which of the following normally results from
meiosis in a human cell that contains 46
chromosomes? A. an egg cell with 46 chromosomes
B. a liver cell with 23 chromosomes C. a
blood cell with 46 chromosomes D. a sperm cell
with 23 chromosomes
5
The cell organelle shown below produces ATP and
is found in most eukaryotic cells that require
large amounts of energy. The highest
concentration of such organelles would be found
in which type of human cell?
A Bone B Skin C Muscle D Fat
6
Energy?

  • Male peafowl, called peacocks, have long,
    colorful tail feathers. Among peacocks there is
    variation in the size, brightness, and pattern of
    the tail. Scientists observed the mating success
    of two groups of peacocks. The graph below shows
    the scientists data.
  • Explain what the data show about the advantage of
    longer, more colorful tails for peacocks.
  • Identify one disadvantage that longer, more
    colorful tails have for peacocks.
  • Explain in detail how the longer, more colorful
    tails evolved in peacocks despite causing
    disadvantages for the males.

9
  • In 2006, scientists discovered fossilized
    skeletons of an animal with several interesting
    features. Fossil evidence indicated that the
    animal not only had scales, fins, and gills, but
    also had lungs, a full set of ribs, and limb
    bones arranged to support the animals weight.
    The illustration below shows what the animal,
    called Tiktaalik, probably looked like based on
    the fossil evidence.
  • Which of the following statements best explains
    why the Tiktaalik fossils are an important piece
    of evidence for evolution?
  •   A.They include skeletons of both males and
    females.
  •   B.They are complete skeletons of a carnivorous
    animal.
  •   C.They allow scientists to estimate the
    animals lifespan.
  •   D. They show a transitional form between fish
    and land-dwelling vertebrates.

Heat
  • Heat flows from where it is to where it is not.
  • The rate of heat exchange depends upon the
    temperature difference.
  • Different substances have different abilities to
    conduct heat. The energy required to raise 1
    gram/ 1 degree celsius is a Kelvin, what is it in
    SI?
  • What are the 3 methods of heat transfer?

  • The Moon produces no light, and yet it shines at
    night. Why is this?
  • A. The Moon reflects the light from the Sun.
  • B. The Moon rotates at a very high speed.
  • C. The Moon is covered with a thin layer of ice.
  • D. The Moon has many craters.

Table 5b-1 Evolution of the Earth's atmosphere.
Name of Stage Duration of Stage (Billions of Years Ago) Main Constituents of the Atmosphere Dominant Processes and Features
Early Atmosphere 4.4 to 4.0 H2O, hydrogen cyanide (HCN), ammonia (NH3), methane (CH4), sulfur, iodine, bromine, chlorine, argon Lighter gases like hydrogen and helium escaped to space. All water was held in the atmosphere as vapor because of high temperatures.
Secondary Atmosphere 4.0 to 3.3 At 4.0 billion H2O, CO2, and nitrogen (N) dominant. Cooling of the atmosphere causes precipitation and the development of the oceans. By 3.0 billion CO2, H2O, N2 dominant. O2 begins to accumulate. Continued release of gases from the lithosphere. Water vapor clouds common in the lower atmosphere. Chemosynthetic bacteria appear on the Earth some time between 3.9 and 3.5 billion years ago. Life begins to modify the atmosphere.
Living Atmosphere 3.3 to Present N2 - 78, O2 - 21, Argon - 0.9, CO2 - 0.036 Development, evolution and growth of life increases the quantity of oxygen in the atmosphere from lt1 to 21. 500 million years ago concentration of atmospheric oxygen levels off. Humans begin modifying the concentrations of some gases in the atmosphere beginning around the year 1700.

environmental temperatures are highest. B Gila
monster populations are largest when
environmental temperatures are highest. C
Increases in Gila monster body temperatures
directly affect the environmental temperature. D
Increases in environmental temperatures cause
Gila monster body temperatures to increase.
