Question	Answer
what theme or themes are exemplified by (a) the sharp spines of porcupine b the cloning of a plant from a single cell and c a hummingbird using sugar to power flight	structure and function, cells are an organisms basic unit of life, and continuity of life is based on heritable info,
give an example of each theme	Emergent: The heart needs intact pieces to pump blood because other pieces alone will not fulfill it Environmental interactions: a mouse eaten by a predator, Energy transfer: grass turns sun energy into fuel, Structure function: wolf teeth eat prey,
continued	cellular basis of life: chemicals allows for digestion made by different cells in digestive tract, Genetic basis of life: eye color based on inheritance, Feedback: full stomach sends feedback to brain to decrease appetite, Evolution: all plants have chlor
How is mailing address analogous to biology's hierarchical taxonomic system	like an adress, groups- subordinates to group- narrows down to certain structures of biology like adress can go state, city, zip code
explain why editing is an appropriate metaphor for how natural selection acts on a poplulations heritable variation	it is edited because better suited traits survive and reproduce
what if fungi and animals are more closely related to each other than either kingdoms is to plants?	they were probably closer related in past species
contrast inductive reasoning with deductive reasoning?	inductive reasoning gets generalizations from specifics, deductive predicts specific based on general premises
in the snake mimicry experiment, what is the variable?	color of snake
why is natural selection a theory	it is more broad than a hypothesis and applies to all kind of organisms with a lot of background
suppose you extended the snake mimicry experiment to an area of Virginia where neither type of snake is known to live there? predict results	it would probably be attacked more due to it's bright colors and less organisms would fear it
how does science differ from technology?	science wants to understand natural phenomena while technology involves application of scientific discoveries for a particular purpose to solve a problem
higher percentage of residents of africa than u.s africans have sickle cell gene and the gene may protect from malaria. Why in evolutionary terms do you believe this happens	natural selection. those with sickle cell may have desired genes to survive in Africa because of malaria while in America this advantage is not seen
why is evolution considered the core theme of biology?	evolution explains the most fundamental aspects of all life on earth. it accounts for the common features shared by all forms of life due to descent from a common ancestor. while also providing an explanation for how the great diversity has arisen
how could natural selection have led to the evolution of adaptations such as thick, water conserving leaves of the mother of pearl plant on cover of this book?	plants that could conserve water better could have did a better job surviving and this would lead to my reproduction of this plant and over time others would die off
what are the roles of inductive and deductive reasoning in the process of scientific inquiry	inductive allows for hypothesis formation while deductive leads to predictions that are used to beat hypothesis*
Explain why different approaches and diverse backgrounds among scientists are important	more is learned because of different ideas that innovations can rise where culture can coexist
all organisms on campus make up?	community
what is the correct sequence of levels in life's hierarchy proceeding down from an individual animal	nervous system, brain, nervous tissue, cell, organ
what was not obeserved by darwins theory natural selection	poorly adapted individuals never reproduce
system biology is mainly an attempt to	understand the behavior of entire biological systems
protists and bacteria are grouped into different domains because	protists have a membrane bound nucleus, which bacterial cells lack
what best demonstrates the unity among all organisms	the structure/ function of dna
a controlled experiment is one that	tests experimental and control groups in parallel
statement distinguishing hypotheses from theories	hypotheses are narrower in scope, theories have broad explanatory powers
example of qualitative data	fish swam zigzag
best describe logic of scientific inquiry	if hypothesis is correct, expect certain test results
