Characteristics of Life
What is the basic unit of structure and function in all living things?
The cell
The second step of the scientific method
Hypothesis
Information gathered from making observations during an experiment is called what?
Data
What is a group of similar cells performing a specific function called?
Tissues
Anything in the environment that causes an organism to react is called a what?
Stimulus
The process by which organisms maintain a stable internal environment is called what?
Homeostasis
What format should always be used when writing a hypothesis?
If..then...
Data that involves measurements or numbers is called what?
Quantitative
A group of organs working together to perform a major body function is a(n) what?
Organ Systems
In a feedback loop, which organ/structure acts as the primary Control Center for thermoregulation?
Brain
What is the difference between growth and development?
Growth is an increase in living tissue/size, while development is the sum of changes over an organism's life.
In an experiment, which variable is deliberately changed
The manipulated variable
Data consisting of descriptive words, pictures, or observations is called what?
Qualitative
What term describes a group of the same organisms living in the same area?
Population
What mechanism does the body use to bring a variable back to balance when it shifts too high or too low?
Negative feedback loop
Name the 6 characteristics of life.
Made of cells with DNA, reproduce, grow & develop, adjust to environment, use energy, adapt & evolve.
An experiment that tests the effect of only a single variable at a time is called a what?
A controlled experiment
Is "the plant grew 3 cm" quantitative or qualitative data?
Quantitative
If prairie dogs live in two completely separate geographical areas, are they part of the same population? Why or why not
No, different area
In the thermoregulation feedback loop, what is the response when body temperature drops on a freezing morning?
Shiver
What is the difference between sexual and asexual reproduction?
Asexual - One parent - genetically identical offspring
Sexual - Two parents - genetically different offspring
Why is a control group essential in an experiment?
It shows the MV caused the change
Is "the frog's skin is dark green and bumpy" quantitative or qualitative data
Qualitative
Sequence these levels of biological organization from smallest to largest: Organism, Cell, Tissue, Organ System, Organ.
Cell- tissue - organ - organ system - organism
Put the 7 steps of a homeostasis feedback loop in order: Receptor, Control Center, Stimulus, Levels Back to Normal, Output, Input, Response.
Stimulus - Receptor - Input - Control Center - Output - Response Levels Back to normal
