Module 1 Assignment - Introduction to Biology and Scientific Method
Part 2 for drag and drop question Not a property of all living things
- composed of many cells - individuals evolve over time - eats other organisms to gain energy - requires another individual to reproduce
Part 1 for drag and drop question. A property of all living things
- reproduces its own kind - complex, but well-ordered, structure - Populations evolve over time - takes in, converts, and expels energy - response to the environment
The collared lizard study What is the hypothesis of this case study?
A function of male coloration is to attract females.
A hypothesis is a(n) ______________.
A proposed explanation for a set of observations
Which of these is required for natural selection to occur?
All of the answers are correct
The collared lizard study If the proportion of brightly colored mail lizards increased steadily in the future generations, this would ________.
Be an example of evolution due to natural selection
The _____________ consists of all the parts of the Earth that are compatible of supporting life
Biosphere (Extra info: The first use of the term biosphere was by a geologist named Edward Suess in 1875.)
What are genes composed of?
DNA
Information flow and biological systems is necessary for negative (regulative) feedback to operate. Which of these examples does not involve flow of information providing feedback?
Drought kills many trees.
Even though biology is a broad field of study, ___________ serves as a central theme that unifies all of biology.
Evolution. (Extra info: Evolutionary theorist Theodosius Dobzhansky wrote that without the light of evolution, biology "becomes a pile of sundry facts some of them interesting or curious but making no meaningful picture as a whole.")
The collared lizard study What conclusion can be drawn from the data?
Females do not always choose brightly colored males. (This one is tricky because it may seem like none of them are right.)
Which statement is a valid scientific hypothesis?
Humans and bacteria share a common genetic code.
You try to start your car, but it does not start. Which of these is a prediction?
If I recharge the battery, then my car will start.
Imagine a human made object that can assemble identical copies of itself, process energy, and adjust his internal environment to external changes. Is this hypothetical or look in the sample of life?
Not necessarily, because although it exhibits most of the properties of living organisms, it does not exhibit all of them. (Don't forget to read the extra info after you input the answer. It's very useful.)
What are the two main processes that the systems depend upon?
Nutrient recycling and energy flow
The collared lizard study " male colored lizards show considerable color variation" This is a(n) __________.
Observation
Which function is NOT a property of life?
Populations of organisms rarely change over time.
Which of these is a key feature of the scientific process?
Scientific hypotheses must be testable.
Which of these statements is CORRECT?
Scientific ideas are subjected to repeated testing.
The collared lizard study Dull-colored males were used in this experiment to ________.
Serve as a comparison (control) group to the brightly colored males
What does "adaption" in an evolutionarily context?
The accumulation of favorable variations in a population over time (It'll be tempting to say all of the above, but the third option is wrong.)
Which information flow is disrupted when diabetes destroys insulin-producing cells?
The body is unable to respond to signals that indicate the amount of glucose in the blood.
How do hypotheses differ from theories?
Theories are more comprehensive than hypotheses.
Which of the following best describes a theory?
a comprehensive explanation of natural phenomena supported by abundant evidence (Extra info: theories are supported by the accumulation of extensive and varied evidence.)
Which substance is not recycled but rather is lost from ecosystems?
energy
The emergence of antibiotic resistance and hospital settings indicates that ______________.
heritable variations already existed among individuals within the population (There will be extra info.)
What name is given to a proposed explanation for a set of observations?
hypothesis
In his book The Origin of Species, Darwin argued that species living today descended from a succession of ancestral species. What mechanism did Darwin propose to explain how evolution occurs?
natural selection
Which concept was proposed by Darwin?
natural selection
What name is given to the functional compartments of the cell?
organelles
Most plants are ________.
producers
Science is _______.
the inquiry-based effort to describe and explain nature
Antibiotic resistance evolves in bacteria when ________.
the presence of antibiotics favors bacteria that already have genes for resistance
Which of these scenarios is the result of natural selection?
the proliferation of pesticide-resistant insects
What is biology?
the scientific study of life
The ________ is the smallest unit that can display all the characteristics of life.
cell
Which structure can perform all the activities required for life?
cells
Which of these is an ecosystem?
Lake Erie and everything living in it (This is correct because this includes both the living and nonliving components of the particular area.)
What mechanism might explain why polar bears are white and bears sounds farther south have a darker color?
Natural selection (The extra info shown after you put in the answer is interesting.)
What process accounts for the different breeds of domesticated dogs?
artificial selection
In science, theories _____.
can tie together a large number of observations that previously seemed unrelated
