Which of the following statements about the "tree of life" is correct?
Before Carl Woese, all cellular life forms were classified into five kingdoms: Monera, Fungi, Plants, Animals, and Protists.
Using rRNA genes for phylogenetic reconstruction, Carl Woese uncovered a previously unrecognized group that was thought to be bacteria. Afterward, all cellular life forms were classified into three domains: Archaea, Bacteria, and Eucarya.
It is found that the relationship among Archaea, Bacteria, and Eucarya changes, depending on which gene was used for phylogenetic reconstruction.
All of the above
QUESTIONS
1.
a) The earth's inner core is just a few hundreds of degrees less than the temperature of the
Sun: about 5200 degrees Celsius versus about 6000 Degrees Celsius. With that much heat
in the centre of the earth, why is it still possible for life to exist on the surface of the
earth?
b) How is the heat in the earth's centre able to melt the outer core but not the inner core?
2). a). Describe the Goldsmith Classification of element.
b). Describe how Goldsmith rules are used to classify Elements.
c). Describe how the bonding types and magma differentiation aids in the distribution of
trace elements in the Earth

Group of answer choices There is much scientific evidence suggesting that all creatures living on Earth today appear to have evolved from a common ancestor. Louis Pasteur discredited the concept of spontaneous generation by demonstrating that even bacteria and other microorganisms arise from parents resembling themselves. There is ample physical evidence that the earliest life forms on Earth were multicellular creatures, perhaps resembling some of our primitive fish. When the earth formed some 4.6 billion years ago, it was a lifeless, inhospitable place.
