Elements of an experiment
What is a control group?
The base line group of an experiment
What is a laser?
Light amplification by stimulated emission of radiation.
Define system?
A collection of interaction, interrelated, or interdependent parts that can work together to make into a complex whole.
What's a closed loop system?
A self-regulated mechanism that uses feed back to maintain a specific output.
What is Mendelian genetics?
Set of fundamental principles that shows how traits are passed on from parents to their offspring.
What is a constant?
Things that keeps the same.
What are some uses of genetic engineering?
Develop medical therapies, GMO crops, industrial uses, cleaning environment
Describe what is system input.
Any matter, energy, or raw material that enters the system.
Difference between open and close loop system.
Open loop system do not monitor feedback. Closed loop system monitor the out put and adjust the input, make it more accurate and stable.
How does mendelian genetics works?
Inherit two copies of each gene. Which separate during gamete formation.
What are the difference between independent and dependent variables?
Independent variable is what the researcher control, the dependent variable is the outcome
What is artificial intelligent?
A kind of complex computer system that is capable of solving tasks.
what is the purpose of a system?
A way to solve the problem and prove the output is correct.
What is the purpose of a open loop system?
To provide a simple and reliable control method for predictable tasks.
Describe the newton’s law of motion.
Describes the relationship between physical objects and the force acting upon it.
What’s the purpose of control group in a science experiment?
As a baseline for comparison.
The two main scientific theory does space travel use?
Newton's law of motion, law of universal gravitation.
Why is photosynthesis important?
Use solar energy to create glucose also creates the base of the good chain like oxygen, and process the global carbon cycle.
What kind of system is the human body temperature regulation?
Closed loop system.
Describe why Mendelian genetics is important.
It established that traits are inherited through discrete units.
Parts of a conclusion
Summarize the result, find supporting data, explain error during the experiment.
How does nuclear fusion works?
Combine light atomic nuclei under extreme heat and pressure.
What is the system input, system process, and the system output of the human nervous system?
Input: sensory, collect information from surrounding area. Process: integration, occur in brain to interpret data. Output: motor, the brain will send signals to muscle to have reaction.
What are the elements of a open loop system.
Controller, actuator, and controlled process.
Describe how the newton’s law of motion shows in cars.
The first law explain why the car need seat belts. The second law dictates more forces is needed for heavier cars. The third law allows wheels pushing backward on the road to propel the car forward.
