Cell Basics
This type of cell has a nucleus and membrane-bound organelles.
What is a eukaryotic cell?
These biomolecules are the main source of quick energy for the body.
What are carbohydrates?
DNA stands for this.
What is deoxyribonucleic acid?
A group of the same species living in the same area.
What is a population?
This system transports nutrients, oxygen, and waste.
What is the circulatory system?
The jelly-like fluid that fills a cell and holds organelles in place.
What is cytoplasm?
Enzymes belong to this category of biomolecules.
What are proteins?
This process copies DNA before a cell divides.
What is DNA replication?
This process is described as "survival of the fittest."
What is natrual selection?
This system protects the body from disease and infection.
What is the immune system?
Unlike animal cells, plant cells contain this rigid outer layer.
What is a cell wall?
Lipids are important because they make up most of this cellular structure.
What is the cell membrane?
A chart used to predict possible genotypes of offspring.
What is a Punnett Square?
The path of energy from one organism to another.
What is a food chain?
This system breaks down food for nutrient absorption.
What is the digestive system?
These tiny structures are the site of protein synthesis in all cells.
What are ribosomes?
These biomolecules store genetic information.
What are nucleic acids?
The two stages of protein synthesis are this.
What are transcription and translation?
This type of succession occurs after a natural disaster.
What is secondary succession?
This system is responsible for sending signals using neurons.
What is the nervous system?
Name two differences between prokaryotic and eukaryotic cells.
Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
These four elements are the most common in organic biomolecules.
What are carbon, hydrogen, oxygen, and nitrogen?
A change in the DNA sequence is called this.
What is a mutation?
Two examples of evidence for evolution are discussed in the video.
What are fossils and DNA similarities?
Name at least three organs in the excretory system.
What are the kidneys, bladder, and urethra?
