Classification and other review
This is the most specific level of classification (most detailed "box").
Species
What are some things humans do that negatively impact the environment?
reduce habitat size, deforestation, clearing land to build things, pollution, over hunting, poaching, overfishing, ect
What is the basic unit of life?
a cell
What is a hypothesis?
testable explanation
Tell me about a stimulus and response in the wild
cat walks by, dog barks
The scientific name for African Pygmy Dormouse is Graphiurus murinus. What is the Genus name.
Graphiurus
what happens when two animal species depend on the same source of food?
competition - leading to natural selection - those that have adaption that help them survive/thrive better will get to reproduce
regulation of an organism's internal environment to maintain conditions needed for life
homeostasis
What are significant figures (sig figs).
Way to write measurements that show accuracy of tool used
Name two organisms that are in the same kingdom but not in the same phylum.
Butterfly and Dog
What type of things are considered fossils?
seashells encased in mud; imprints in rocks; bones buried; specimen preserved in ice
What are examples of inheritable traits?
anything not acquired after birth (injuries, accents, tattoos, hair dye)
What does it mean to respond to stimuli?
react to something in your enviroment
What are the steps of the scientific method
observation, question, hypothesis, experiment, conclusion, share results
Name one way animals or humans maintain homeostasis
shivering
What does Eutrophication mean and how is it caused?
Nitrogen runs off into water from fertilizer, causes algae bloom (algae explode in population); sucks all the O2 out of the water and blocks sunlight, sufficates animals and plants underneath, other plantlife below dies.
Water - moves water around the system, evaporation, precipitation, condensation, run off ect
Nitrogen - nitrogen is unusable in air form, bacteria must fix it, comes from ammonia mostly (urine/when animals/plants die) - needed for DNA building
Carbon - dead animals and waste getting broken down. burning fossil fuels - building block of life; Respiration cycles
Inherited changes that occur overtime to help a species survive
adaptations
Define each part: 1. Independent variable; 2. Dependent variable 3. Constant
IV - what I change
DV - what changes because of what I changed
Constant - things I keep the same on purpose
What makes two animals a part of the same species?
They can reproduce and make fertile offspring; don't view other species as viable mates. have a common ancestor
How are photosynthesis and Cellular Respiration a cycle?
the outputs of one of the inputs of the other
What are the three symbiotic relationships and how are each organism affected?
parasitism - +; -
Mutualism - +; +
Commensalism - + ; 0
Which characteristic of life is not essential (does not HAVE to occur to still be considered living)?
Reproduction
Describe how observation or data that are inconsistent with theory should be treated
review, retest, adjust theory if needed
Which is the process that results in mass being added to an organism that may include formation of new cells and new structures?
growth
