Which of the following is true? - A scientific theory is a hunch about a natural event. - A scientific theory explains what we know to this date about a natural phenomenon, often with considerable experimentation and observation for confirmation. - A theory is not falsifiable. - A scientific fact and a scientific theory carry the same weight in the scientific community.
A scientific theory explains what we know to this date about a natural phenomenon, often with considerable experimentation and observation for confirmation.
Identifies best practices, using evidence, to make informed decisions
Applied Science
The production of the mRNA Covid-19 vaccines is an example of which of the following?
Applied Science
Explain how the world works
Basic Science
Which of the following aligns with what researchers found related to the impact of animal diversity and measured increases in Lyme disease? - By decreasing the number of dilution hosts prevalence of lyme disease increases - None of the above - By introducing new hosts to the environment the likelihood of contracting lyme disease increases. - By increasing the number of dilution hosts prevalence of lyme disease increases.
By decreasing the number of dilution hosts prevalence of lyme disease increases
Measurements at Mauna Loa show atmospheric CO2 increased dramatically since the 1950s. However, the rise has not been steady. CO2 rises and falls each year, creating a sawtooth pattern. What drives the annual upswing in CO2? - CO2 increases when photosynthesis < respiration in Northern Hemisphere - CO2 increases when photosynthesis < respiration in Southern Hemisphere - CO2 increases when photosynthesis > respiration in Southern Hemisphere - CO2 increases when photosynthesis > respiration in Northern Hemisphere
CO2 increases when photosynthesis < respiration in Northern Hemisphere
The majority of actual dry weight (biomass) gained by plants as they grow enters the plant from which of the following sources? - Nitrogen dissolved in water taken up by plant roots - Energy from the sun captured by leaves - Calcium dissolved in water taken up by plant roots - Carbon dioxide in the air that enters through the leaf - Organic substances in soil that are taken up by plant roots
Carbon dioxide in the air that enters through the leaf

True or false: Ticks are a dilution host for Lyme disease.
False, possums are a dilution hosts for lyme disease
Which of the following is not an example of replication in an experimental design? - Applying the experimental and control treatments to multiple experimental units each - Holding constant all variable, except the independent variable, between groups - Taking multiple measurements of the dependent variable - Repeating the entire experiment
Holding constant all variable, except the independent variable, between groups
______________ reasoning is a type of logical thinking where one uses related observations to arrive at a general conclusion
Inductive

Forest ecosystems are an important source of new pharmaceuticals. What class of ecosystem services are medicines harvested from forests?
Provisioning
Barrier islands often help buffer the effects of storm surge caused by hurricanes. What class of ecosystem services does this fall under?
Regulating
Is the following statement true or false? "The species accumulation curve of a designated study area gives the expected number of observed species as a result of sampling effort."
True
True or False: An experimental unit is the subject that receives a treatment or intervention and is the main focus of the study, from which a response variable will be collected.
True
