Characteristics of Life
What is the basic building block of all living things?
The Cell
What does “homeostasis” mean?
Maintaining a stable internal environment.
Name the molecule that stores genetic information.
DNA
Does Evolution happens to individuals or populations?
Populations
Why is energy important for living things?
Needed for growth, repair, and all life processes.
What do we call the set of traits that all living things must have?
Characteristics of Life/living things
Give one example of homeostasis.
Sweating, shivering, plants regulating water, etc.
What is heredity?
Passing traits from parents to offspring.
What causes evolution to happen?
Reproduction + trait differences + natural selection.
What do autotrophs do for energy?
Make their own food.
What characteristic explains why a whole species changes over many generations?
Evolution
What is metabolism?
The sum of the total of the biochemical reactions occurring in an organism.
Give one example of a trait passed from parents to offspring.
Hair color, eye color, dimples, etc.
Give one example of evolution.
Pesticide resistant bugs / antibiotic-resistant bacteria, finches beaks
What do heterotrophs do for energy?
Consume other organisms.
What characteristic explains why life continues from one generation to the next?
Reproduction
It provides energy and materials for growth, repair, and life processes.
What is one benefit of asexual reproduction?
Quick, doesn’t require a mate, makes many.
How are reproduction and evolution connected?
Only traits that get passed down can cause evolution over generations.
Give an example of an autotroph.
Plants, algae
What are the 8 characteristics of Living things?
cells, develop/grow, respond to stimuli, metabolism, reproduce, homeostasis, evolution, DNA
How does responding to stimuli help organisms survive?
Helps them avoid danger, find food, and adapt.
What is one benefit of sexual reproduction?
Genetic diversity
Why do scientists think evolution is important?
It helps species adapt and survive environmental changes.
Give an example of a heterotroph.
Humans, animals, fungi.
