What are the levels of organizations (smallest to largest)

Molecules
Macromolecules
Macro molecular assembly
Cell
Tissue
Organ
Organ system
Organism
Does correlation guarantee causation?
No, if a hypothesis is supported it may suggest causation
Hypothesis
Tentative explanation
What is a prediction?
Expected outcome
Where does the Dependent variable go in the axis’s?
Y axis
Where does the Independent variable go in the axis’s?
X axis
What’s inductive reasoning?
An observation that arrives to a theory
What’s deductive reasoning?
A theory that arrived to observations
Why is a peer review important?
It measures the strength and credibility of your data
What causes climate change? (Name At least 3)
Green house gases
Deforestation
Albedo effect
Deterioration of ozone layer
Suns luminosity increase
Volcanoes
Natural variation
Why is there a correlation between CO2 and temperature?
If temperature increases, more carbon dioxide is being exposed. If carbon dioxide emissions increases, more heat is going to be released to the atmosphere
Deforestation
Land use change
What is climate change?
Directional change to the global climate that last for more than 3 decades.
What has climate change affected?
Wind patterns
Storms droughts
Deforestation
Animal extinction
What is evolution?
Process of change overtime that has resulted in the outstanding array of organisms found on earth.
Difference between prokaryotes and eukaryotes?
Prokaryotes lack a nucleus and eukaryotes don’t. They also contain cytoplasm and chloroplast.
What is DNA?
Deoxyribonucleic acid
Genes
Each section of the DNA of a chromosome
Gene expressions
The sequence of genes that provides a blueprint for protein production
What are the 4 binding nuclei acids ?
A-T and C-G
What does an Antibody do?
Fights infections
MRNA _ protein
Transfers
Genomics
Entire library of genetic instructions of an organism
How much is the Earth heating up?
Two degrees
What is the green house effect ?
Gases that are trapped in our atmosphere that trap and slow down heat that would escape the earth
How does the GHE causes global warming?
Many trapped gases such as Carbon dioxide and methane are being trapped because of the amount of emissions
How do we know humans are responsible for the increase
in carbon dioxide?
Due to human activity such as burning of fossil fuels and natural emissions
Why do people deny the science of climate change?
Market orientations
What could happen for such change in climate ?
Extreme weather, lots of animal habitats, deterioration of ice caps.
What is the Paris agreement?
Virtually every country agreed to limit future emissions.
Does clean energy help or hurt the economy?
Good: Job growth in renewable energy is strong
Bad: costly
What is fracking ?
Hydraulic fracturing that excavates coal instead of burning
What is clean coal?
Approach in which emissions from coal burning power plants would be captured and pumped under ground
scientific hypothesis
if then and because
statistical hypothesis
showing correlation
null hypothesis
showing no correlation between variables
alternate hypothesis
correlation between two variables
prediction
what you expect to happen
theory
prediction or hypothesis tested and proven to be true yet falsified
