Module 1 (vocabulary is on Biology ipad app) Flashcards
What are the four criteria for life?
- All life forms contain deoxyribonucleic acid, which is called DNA.
- All life forms have a method by which they extract from the surroundings and convert it into energy that sustains them.
- All life forms can sense changes in their surroundings and respond to those changes.
- All life forms reproduce.
An organism is classified as a carnivore. Is it a heterotroph or an autotroph? Is it a producer, consumer, or decomposer?
Heterotrophs, which are also known as consumers
An organism has receptors on tentacles that come out of its head. If those tentacles were cut off in an accident, what life function would be most hampered?
sensing changes in the surroundings and responding to those changes will be hard for this wounded creature
A parent and two offspring are studied. Although there are many similarities between them, there are also some differences. Do these organisms reproduce sexually or asexually?
sexually
What is wrong with the following statement?:
“Science has proven that energy must always be conserved.”
Science cannot prove anything
Briefly explain the scientific method.
In the scientific method, a person starts by making observations. The person then develops a hypothesis to explain those observations or to answer a question. The person (often with the help of others) then designs experiments to test the hypothesis. After the hypothesis has been tested by a significant amount of data and is consistent with all of it, then it becomes theory. After more testing with generations of data, the theory could become a scientific law.
Why does the story of spontaneous generation illustrate the limitations of science?
it shows how almost 2,000 years of executing the scientific method resulted in a law that was clearly wrong
Where does the wise person place his or her faith: science or the Bible?
Bible
Why is the theory of abiogenesis just another example of the idea of spontaneous generation?
Abiogenesis is a theory that states that life sprang from non-living chemicals eons ago. This is an example of spontaneous generation, a former law that said life could arise from non-life.
Name the classification groups in our hierarchical classification scheme in order.
Kingdom, Phylum, Class, Order, Family, Genus, Species
An organism is a multicellular consumer made of eukaryotic cells. To what kingdom does it belong?
If we were using the three-domain system of classification, in which domain would the organism belong?
Animalia; Eukarya
An organism is a single-celled consumer made of prokaryotic cells. To what kingdom does it belong? If we were using the three-domain system of classification, could you determine the domain of the organism? If so, give the domain. If not, give the possible domains in which it could be placed.
Monera; You cannot tell which domain without knowing more about the organism. However, it is either in Archaea or Bacteria, depending on its characteristics.
