Light Pink Biology Words

• What is Recombinant DNA Technology?

  Comprises of altering genetic material outside an organism to obtain enhanced and desired characteristics in living organisms
• Stem Cells, Embryonic Cells?

  Created by introducing new genetic materials into an embryo of an organism (Can be passed onto offspring)
• Stem Cells, Adult Transgenic Organism?

  Introducing new genetic material into cells of an already developed organism (Cannot be passed onto offspring)
• What is Coevolution?

  When two or more species have a close relationship and influence each other's evolution
• What is Genetic Drift?

  Where the frequency of certain genes within a population can change by chance (Random)
• What is Isolation?

  The separation of a species or population, preventing it from interbreeding with other members of its species
• What is Speciation?

  The process by which new species arise from a single ancestral species
• What is Punctuated Equilibrium?

  Theory that suggests that species often evolve in rapid change followed by long periods of stability where little change occurs
• What is a Cladogram?

  Diagram used to show the relationships between different groups or organisms based on shared characteristics
• What is Gradualism?

  Theory that suggests that evolution occurs gradually and continuously over a long period of time (Changes slow and steadily)
• What is Prokaryotic?

  Simple cells that don't have a distinct nucleus or other membrane-bound organelles, smaller and less complex than Eukaryotes
• What is Eukaryotic?

  More complex cells that have a distinct nucleus enclosed within a membrane along with other membrane bound organelles
• What is Conjugation?

  The process of genetic transfer between two bacterial cells
• What are Ecological Roles?

  The specific functions and interaction that a species has within an ecosystem
• What is Radial Symmetry?

  Body parts are arranged around a central axis (Like jellyfish and sea anemones)
• What is Bilateral Symmetry?

  Has a distinct front and back, as well as top and bottom (Like worms, insects, and mollusks)
• What is Asymmetry?

  Displays asymmetrical body structures where there isn't a specific symmetry pattern (Like Sponges)
• What is Spherical Symmetry?

  Similar body parts radiate from a central point in multiple directions
• What is the Nervous System?

  Complex network of nerves and cells that transmit signals between different parts of the body
• What is Cephalization?

  The evolutionary trend where nervous tissue, sensory organs, and feeding structures become concentrated in the head or end of an organism
• What is Organization?

  The arrangement and structure of the components within an organism as well as the coordination of those components to carry out specific functions
• What are Digestive Tracts?

  Long hallow tube that extends from the mouth to anus and its responsible for the digestion and absorption of food and nutrients
• What is a Filter Feeder?

  Feeds by straining matter and food particles from water
• What is Cellular Respiration?

  Process where cells break down glucose and other food molecules to produce energy in a form of ATP
• What is the Neuron function?

  Specialized cells that transmit information in the form of chemical and electrical signals
• Brain function?

  Processes information from senses, controlling movements, regulating bodily functions like breathing and heart rate
• Blood Flow Pattern?

  Heart pumps oxygen rich blood to body through arteries, delivers oxygen and nutrients to tissues, blood returns to heart then gets oxygenated
• Blood Pressure?

  The force of blood pushing against the walls of your blood vessels
• Heart Function?

  Pump blood throughout body, when heart beats it sends oxygen and nutrient rich blood to organs and tissues
• Blood Clotting?

  When a blood vessel is damaged, platelets arrive first to plug the hole then a series of chemical reactions happen to form a clot to stop the bleeding and heal the wound faster
• Regulation of Breathing?

  When your brain senses a change, it sends signals to your diaphragm and other breathing muscles to speed up or slow down
• Regulation of Blood?

  Involves many various systems working together, like insulin controlling blood sugar levels
• What is Homeostasis?

  Many different systems working to regulate and maintain a stable environment inside you
• What is Symbiosis?

  Relationship between organisms
