BSC 108 Exam 1 -ALABAMA Domain Eukarya contains animals, plants, protists, and fungi. - ✔✔True The process of keeping internal conditions constant is known as - ✔✔Homeostasis The levels of biological organization, in order from least complex to most complex, are: biospher e, ecosystems, communities, populations, organisms, organ systems, organs, tissues, cells, atoms, molecules. - ✔✔False A new species has been discovered. Individuals of this species are multicellular eukaryotes that obtain nutrients from decomposing organic matter. In which domain should this species be classified? - ✔✔domain Eukarya Communities are more complex than popu lations. - ✔✔true What is the lowest level of structure that can perform all activities required for life? - ✔✔cells A tentative explanation of an observation is - ✔✔hypothesis A collection of hypotheses that have been repeatedly tested without rejectio n is called a - ✔✔theory The three domains of life are: - ✔✔Eukarya, Archaea, Bacteria What is the difference between hypothesis and theory? - ✔✔A theory is much broader in scope than a hypothesis and is generally supported by an accumulation of extensiv e and varied evidence. Describe one theory that unifies biology as a science. - ✔✔The theory of evolution by natural selection unifies biology as a science because it accounts for the unity and diversity of life on Earth. This theory states that there is an overproduction of offspring and competition for resources, and variation exists among individual offspring. Unequal reproductive success (natural selection) among these offspring is the mechanism of evolution. What are the steps used in the scientific method? Use an example to illustrate the steps of the scientific method. - ✔✔a)Observations, Question, Hypothesis, Prediction, Test, Revise hypothesis or Make additional predictions and test them. Example: I observe that my flashlight does not work. I ques tion whether the batteries are dead. I hypothesize that the dead batteries are causing my flashlight to not work properly. I predict that changing the batteries will cause the flashlight to work again. I test my prediction by replacing the batteries with n ew ones. If the flashlight works, my hypothesis was correct. If not, perhaps make a new hypothesis that the light bulb is dead and need replacement. What is the function of nucleic acids? - ✔✔To store and transmit hereditary information.
