4 Questions With Correct Answers
Define Biology - CORRECT ANSWER✔✔-biology is the scientific study of
| | | | | | | | | |
life
List and explain the characteristics of life (fig 1.2 pg 3) - CORRECT
| | | | | | | | | | | | |
ANSWER✔✔-Order, Evolutionary Adaptation, Regulation, Energy | | | | |
Processing, Reproduction, Response to the environment, Growth and
| | | | | | | |
development, and Energy Processing | | |
List and Explain the levels of Biological Organization - CORRECT
| | | | | | | | | |
ANSWER✔✔-from LG to sm: Biosphere, Ecosystems, Communities, | | | | | | |
Populations, Organisms, Organs, Tissues, Cells, Organelles, Molecules
| | | | | |
Evolution - CORRECT ANSWER✔✔-the process by which different kinds
| | | | | | | | |
of living organisms are thought to have developed and diversified from
| | | | | | | | | | |
earlier forms during the history of the earth.
| | | | | | |
Why is DNA considered the molecule of inheritance? - CORRECT
| | | | | | | | | |
ANSWER✔✔-Short Answer: DNA contains genetic information, which is | | | | | | | |
passed onto offspring.
| |
, Define Population and give examples of populations - CORRECT
| | | | | | | | |
ANSWER✔✔-these consist of all the individuals of a species living within | | | | | | | | | |
the bounds of a certain area.
| | | | | |
Example: A meadow can consist of a population of Day Lily's as well as a
| | | | | | | | | | | | | | |
population of deer | |
Explain Evolution through Natural Selection - CORRECT ANSWER✔✔-the
| | | | | | |
weak are killed off, leaving the strongest to reproduce and create
| | | | | | | | | | | |
offspring best fit to the environment
| | | | |
Explain how adaptations come about through natural selection -
| | | | | | | | |
CORRECT ANSWER✔✔-adaptations occur when the "weak" are killed
| | | | | | | |
off. More of the "strong" are produced, killing off the "weal" gene,
| | | | | | | | | | | |
leaving the "strong" to reproduce
| | | |
Explain why evolution is a central theme in biology. - CORRECT
| | | | | | | | | | |
ANSWER✔✔-Evolutionary change ties all forms of life to a common | | | | | | | | | |
beginning over 4 billion years ago. Evolution theme ties all of biology
| | | | | | | | | | | |
together.
What are the thee domains by which all living organisms are classified? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-Bacteria, Archaea, Eukarya
