Bio 101 Unit 1 Quiz 1
Living organisms share a number of characteristics. These unifying characteristics separate them from non-living things. For each of the following statements, check the statements that correctly distinguish living things from non-living things.
All living organisms are made up of one or more cells. All living organisms reproduce by passing on specific genetic information to future generations. Only living organisms (populations) are capable of evolving. Only living organisms require an input of energy to drive cellular activities. All living organisms maintain a relatively stable internal environmental despite external environment change. All living organisms grow by increasing cell size and/or cell number.
Drag the provided terms on the left to the boxes on the right in order of least inclusive (narrowest category) to most inclusive (broadest category).
Atom, Molecule, Organelle, Cell, Tissue, Organ, Organ system, Organism, Population, Community, Ecosystem, Biosphere
Which of the following is the smallest unit of life?
Cell
Which of the following characteristics is unique to living organisms?
Composed of cells
Which properties (of living organisms) only become evident when the component parts are correctly assembled?
Emergent properties
Edward Jenner noticed that the milkmaids who milked cows by hand often were infected with cowpox and that their infections were mild. He also noticed that these same milkmaids did not contract smallpox, which was a much more serious disease. He presumed that the cowpox infections prevented the milkmaids from contracting the much more serious disease of smallpox. Subsequently he began vaccinating people with the pus-like material from cowpox lesions to determine if his thinking was correct. In the story above, the underlined portion is a(n)
Hypothesis
Drag the part of the scientific method on the left to the example on the right it best matches. Then, drag the sentences into the sequence they would most likely happen following a simplified scientific method.
Observation, Hypothesis, Data collection, Analysis, Peer review
Rank the following levels of biological organization from the lowest level of complexity to the highest level of complexity.
Oxygen atom, DNA molecule, Nerve cell, Nervous tissue, Brain, Fish, School of fish, Group of dolphins fish and algae, Pacific Ocean & its inhabitants, Planet Earth
Which of the following serves as the ultimate source of energy for an ecosystem?
Sun
A hypothesis is best described as
a logical explanation that can be tested.
Through evolution, populations can
adapt to the environment.
Which term BEST describes populations of trees, insects, mammals, fungi, bacteria, and many other organisms that interact in any location?
community
The process of maintaining a constant internal environment is called
homeostasis.
Evolution happens through a number of different mechanisms. One of the mechanisms is called natural selection. Natural selection is:
when organisms survive and reproduce the most successfully, because they are best adapted to their environment.
