Characteristics of Life
This word describes a cell’s ability to maintain internal balance.
Homeostasis
This part of the cell controls what enters and leaves the cell.
The Cell Membrane
DNA is made of repeating units called this.
Nucleotides
An organism that makes its own food is called this.
Producer
Plants use this tissue to transport water from roots to leaves.
Xylem
All living things are made of these basic structural units.
Cells
These are cells without a nucleus.
Prokaryotic cells
This process copies DNA into mRNA.
Transcription
This type of natural relationship benefits at least one organism.
symbiosis
These organisms often live in extreme environments and are not bacteria.
Archaea
The molecule that stores the genetic instructions for life.
DNA
This process moves molecules from high to low concentration without energy.
Diffusion
A Punnett square shows possible combinations of these.
Alleles
This term describes the ability of an organism to survive and reproduce.
Fitness
This is a vertebrate adaptation that protects embryos on land.
The Amniotic Egg
This term refers to chemical reactions in the body that provide energy.
Metabolism
These organelles make energy from food in cellular respiration.
The Mitochondria
This type of mutation changes just one base.
Point Mutation
Random changes in allele frequency, especially in small populations.
Genetic Drift
This group of animals has an exoskeleton and jointed legs.
Arthropods
This process allows living organisms to pass traits to offspring.
Reproduction
This transport process uses energy to move molecules against the concentration gradient.
Active Transport
The process where ribosomes build proteins from mRNA.
Translation
This scientist is known for the theory of natural selection.
Charles Darwin
This term describes animals with a left and right side that mirror each other.
