Study Notes
Biological Hierarchy
- Levels of organization include: cells, tissues, organs, organ systems, and organisms.
- Correct sequence: cells, tissues, organs, organ systems, organism.
Population and Ecology
- In a swamp, alligators represent a population.
- A community includes interactions among multiple populations.
Experimental Variables
- In experiments, the factor that is altered (e.g., temperature in goldfish respiration) is called the experimental variable.
Causes of Stomach Ulcers
- Stomach ulcers are primarily caused by the bacterium Helicobacter pylori.
Development Stages
- The process from fertilization to adulthood, including childhood and adolescence, is termed development.
Organism Classification
- Cells containing a nucleus belong to the domain Eukarya.
Homeostasis Definition
- Homeostasis is the ability of cells and organisms to maintain a relatively constant internal environment.
Relatedness to Humans
- Closely related organisms to humans include meerkats based on evolutionary lineage.
Response to Stimuli
- The sunflower’s movement to follow the sun is an example of response to stimuli.
Science and Technology Perspectives
- Science and technology can be considered value-neutral, recognizing risks alongside benefits.
Data Collection in Experiments
- Information collected during experiments or observations is known as data.
Unifying Principle of Biology
- The unifying principle of biological sciences is evolution.
Theories in Biology
- The theory of gravity is not considered a basic theory of biology.
Study Designs
- A double-blind study is one where neither the patient nor the examiner knows whether the treatment is being administered.
Ecological Interaction Regions
- The region where populations interact with their environment is termed an ecosystem.
Kingdoms in Domain Eukarya
- The domain Eukarya contains four kingdoms.
Human Life Aspects
- Traditions, beliefs, and values are aspects of human life.
Origins of Cell Organelles
- Possible origins of cell organelles in eukaryotes include engulfing heterotrophic bacteria to form mitochondria, but groups of prokaryotic cells living together is not an accepted origin.
Functions of the Cytoskeleton
- The cytoskeleton maintains cell shape, anchors organelles, and facilitates cellular movement but does not process proteins.
Protein Fibers
- Actin filaments are thin protein fibers used for cellular movement.
Nuclear Pore Size
- Nuclear pores in the nuclear envelope are larger than a ribosome.
Glycolysis Evolution
- Glycolysis is believed to have evolved early in life because it does not require oxygen and is present in most cells.
Plasma Membrane Structure
- The plasma membrane contains two layers of phospholipids.
Organelle Functions
- An organelle likened to a post office is the Golgi apparatus, as it processes and distributes proteins and lipids within the cell.
