The study of life
What is biology?
The genetic code of most living things
What is DNA?
The basic unit for measuring length/distance in the metric system
What is a meter?
The first step in the scientific method
What is asking a question or identifying a problem?
Are viruses living things?
It's up to you
The smallest units of life
What are cells?
The rate at which an organism uses energy
What is metabolism?
The basic unit for measuring mass in the metric system
What is a gram?
Step 2: After a question/problem has been established, scientists make an educated guess or prediction called...
What is a hypothesis?
How are sexual and asexual reproduction different?
Sexual reproduction requires two parents and produces offspring with a combination of their genes... asexual reproduction describes a single organism producing a copy of itself
Producing offspring
What is reproduction?
A signal to which an organism responds
What is a stimulus?
The basic unit for measuring volume (the amount of space a liquid takes up) in the metric system
What is a liter?
Step 3: After scientists make a hypothesis, they test it by designing an...
What is an experiment?
Why is it important for organisms to maintain homeostasis?
Homeostasis is necessary for an organism's survival
Reproduction that requires two parents
What is sexual reproduction?
Stable internal conditions
What is homeostasis?
What system of measuring temperature do scientists typically use?
What are degrees Celsius?
Step 4: After testing their hypothesis by conducting an experiment, scientists...
What is analyze the data?
What is one example of how an organism maintains homeostasis?
Regulating temperature, heart rate, breathing rate, blood pressure, water/salt balance, etc.
Reproduction that requires one parent
What is asexual reproduction?
An organism/species changing over generations to help them survive in their environment
What is evolve?
The prefix in the metric system that means 1000x bigger AND the prefix in the metric system that means 1000x smaller
What are kilo (1000x bigger) and mili (1000x smaller)
Step 5: After analyzing data from the experiment, scientists use the information they learn to draw a...
What is a conclusion?
The characteristics that all living things share
They're made of cells, contain DNA, reproduce, grow, evolve, react to their environment, use energy, and maintain stable internal conditions
