Study Notes
Reproduction and Development
- Ensures offspring exhibit characteristics similar to parents.
- Growth and development essential for species continuity.
Regulation and Homeostasis
- Homeostasis maintains internal balance within organisms.
- Regulatory mechanisms include nutrient transport and blood flow.
- Thermoregulation is crucial for controlling body temperature.
Cellular Organization
- Cells are the smallest unit of life, categorized into prokaryotic and eukaryotic types.
- Tissues consist of similar cells performing specific functions.
- Organs are structures formed by different tissues working collaboratively.
- Organ systems consist of groups of organs performing complex functions.
Evolution
- Evolution involves gradual changes leading to the emergence of new species from older ones.
Isotopes and Periodic Table
- Isotopes: Variants of elements with the same protons but different neutrons.
- Carbon-14 dating provides methods to date materials using isotopic composition.
- The periodic table organizes elements by increasing atomic number and similar properties.
Chemical Properties
- Properties of elements largely influenced by outermost electrons.
- Atoms strive for stability through full outer shells, following the octet rule.
- Emergent properties arise in compound structures, differing from individual components.
Steroids and Proteins
- Steroids are lipids with a core structure of four fused carbon rings; they are hydrophobic.
- Cholesterol is vital for maintaining membrane fluidity and synthesizing other steroids.
- Proteins are formed from amino acids linked by peptide bonds, folding into complex shapes.
- Functions of proteins include enzymatic (catalyzing reactions), catabolic (breaking down substances), and anabolic (building compounds).
Microscopy Techniques
- Microscopes are vital for observing cells, magnifying objects and providing clarity.
- Light microscopes can magnify cells up to 400 times with resolution around 200 nanometers.
- Electron microscopes offer higher magnification (up to 100,000x) and resolution (50 picometers) but require sample preparation that kills specimens.
Microscope Components
- Two basic types: simple (single lens) and compound (multiple lenses).
- Essential parts include the base for stability, arm for carrying, stage for slides, and various lenses for magnification.
- Condenser lens enhances illumination and contrast, while iris diaphragm controls light reaching the specimen.
Slide Preparation Methods
- Different slides include flat, concave, dry mount, wet mount (for motile specimens), and smear mount (for blood).
- Staining techniques enhance visibility of cellular structures, aiding identification and observation.
Role of Extracellular Matrix
- The intracellular matrix supports internal processes while the extracellular matrix provides structure and facilitates communication between cells.
