What is The Law of Conservation of Matter (Mass)
Which is the most accurate method scientists use to predict the age of Earth?
What is absolute dating methods (radioactive or radiometric okay)
Name a disease caused by a fungal infection
Athlete's foot, yeast infection, ringworm
Categorize Renewable and Nonrenewable Resources (three each)
What is:
R- Hydropower, Solar, Biomass, Geothermal, Wind
N-Coal, Oil, Nat'l Gas, Nuclear
How can upwellings improve fishing
They bring nutrients (and life) to the surface
Double Jeopardy!
This is a chemical reaction for the decomposition of carbonic acid into water and carbon dioxide. H2CO3 → H2O + CO2 How does the reaction support the Law of Conservation of Mass?
The mass of the products will be the same as the mass of the reactants.
Which is the best reason for scientists to study ice cores obtained from Earth’s ice caps?
What is to study the past atmosphere (climate). Volcano eruptions and temperature okay
How are pandemics different than epidemics?
Pandemics affect many countries (global), an epidemic is more localized.
What happens to most of the energy as it moves throughout a food web?
It is changed (lost) into heat energy.
What are two variables that effect water quality?
What is:
pH, temperature, turbidity, Nitrates and Phosphates, dissolved oxygen levels, and bioindicators
Element X is unreactive, a gas at room temperature, and does not react with other elements. What Family is Element X most likely in?
What is Group 18 (Noble Gases)
Double Jeopardy!
List three different types of evidence for evolution
What is: embryos, DNA, homologous features (anatomy), Law of Superposition (fossils), Continental Drift Theory
What are the three branches of biotechnology, which can improve lives?
What is:
Medical, Agricultural, and Environmental
Where do plants get the food they need for energy?
They produce it (glucose/sugar) during photosynthesis
The part of land drained by a river and its tributaries?
What is a River Basin
What action would have the greatest long-term impact on reducing the amount of carbon dioxide in the air?
What is: Planting trees around farms!
Give an example of how genetic variation may result from a change in the environment where an animal lives?
What is: dark/light fur in an artic environment. Eventually, all will be light
Giraffes, peppered moths?
What is the most likely result of overusing a particular antibiotic?
more infections caused by bacteria resistant to the antibiotic
The following shows the food choices for two species of birds.
Questor- small seeds, flying insects
Wood Plaxer- large berries, beetles
Which will most likely happen to Questors as a result of Wood Plaxers migrating to their habitat?
They will co-exist with no competition
In order to be a good steward of oceans, what is one action that can show concern in regards to resources coming from the ocean?
Limit/prevent overfishing
Which best describes the sequence of the elements in Period 5 of the periodic table?
What is:
highly reactive metals, relatively nonreactive metals, metalloids, and, nonreactive gases
If a bat, an alligator, and a bird evolved from a common ancestor, what most likely can be concluded?
They have similar anatomies (homologous features).
How can biotechnology help farmers overcome sudden changes in the global climate?
by developing crops that are resistant to adverse weather
Why are digestion and respiration important to the body?
They help provide the energy needed for body functions.
