Cell Biology
What is the basic unit of life?
Cell
What does DNA stand for?
Deoxyribonucleic acid
Who is considered the father of evolution?
Charles Darwin
This term describes different species living together in a specific area.
Community
The primary function of this system is to transport oxygen and nutrients throughout the body.
Circulatory system
Which organelle is responsible for producing energy in the cell?
Mitochondrion
Which base pairs with Adenine in DNA?
Thymine
This process is described as the survival and reproduction of organisms best suited to their environment.
Natural Selection
This organism produces its own food through photosynthesis and serves as the base of most food chains.
Grass
This organ is essential for breathing and is part of the respiratory system.
Lung
This part of the cell is selectively permeable, allowing certain substances to enter or leave while blocking others.
Cell Membrane
These are different forms of a gene that can result in variations of a trait.
alleles
Webbed feet in ducks are an example of this trait that improves an organism’s ability to survive in its environment.
Adaptation
In a food chain, energy flows in this direction.
Producer to Consumer
This is the basic unit responsible for transmitting signals in the nervous system.
Nueron
Unlike animal cells, plant cells typically do not contain this structure involved in cell division.
Centrioles
This is the genotype that represents a homozygous dominant trait.
AA
Scientists use these preserved remains to track evolutionary changes over time.
Fossils
This term defines the role or job an organism has in its environment.
Niche
This is where the digestive process begins.
Mouth
Which structure contains a cell’s genetic material?
Nucleus
If tall (T) is dominant and short (t) is recessive, this is the phenotype of a plant with the genotype Tt.
Tall
This is the main reason why genetic variation is essential within a species.
Evolution/Survival
If this important species were removed, the ecosystem would most likely collapse.
Keystone Species
This system controls the release of hormones throughout the body.
Endocrine system
