Flashcards
Feedback Loop
Feedback Loop
A system where the output of a process is used as an input to regulate that same process. Think of it like a thermostat adjusting the temperature based on the room's current warmth.
Selective Pressure
Selective Pressure
The pressure exerted on a population by environmental factors, such as predators, food availability, or disease, that influences which individuals are more likely to survive and reproduce.
Homeostasis
Homeostasis
The process by which organisms maintain a stable internal environment despite external changes. Think of it like a body maintaining a consistent temperature even during the day and night.

Study Notes
Feedback Loops in Organisms
- Feedback loops regulate body systems, like blood sugar.
- These loops maintain internal stability (homeostasis) in organisms by adjusting various physiological processes.
- Negative feedback loops oppose initial change, stabilizing conditions.
Levels of Biological Organization
- Cells are the basic structural and functional units of life.
- Tissues are groups of similar cells working together.
- Organs are composed of different tissues performing specific functions.
- Organ systems are groups of organs working together.
Energy and Cellular Processes
- Review formulas for cellular respiration (relate to energy production).
Natural Selection and Evolutionary Processes
- Natural selection is the process where organisms with advantageous traits are more likely to survive and reproduce.
- Selective pressures are environmental factors driving natural selection.
- Understand how natural selection leads to adaptations and biodiversity.
Homeostasis in Organisms
- Organisms employ various mechanisms to maintain stable internal conditions (homeostasis).
- Processes like regulating temperature, water balance, and blood sugar exemplify homeostasis.
Scientific Argumentation
- Construct scientific arguments using a claim, evidence, reasoning, and counterclaim structure.
Antibiotic Resistance
- Antibiotic resistance is the ability of bacteria to survive exposure to antibiotics.
- Particular bacteria develop resistance due to specific mechanisms.
Bacteriophages
- Bacteriophages are viruses that infect and replicate in bacteria.
- Bacteriophages can be used to combat antibiotic-resistant bacteria.
Models and Midterm Prep
- Study and practice "models" questions (similar to midterm written response questions).
