Study Notes
Laboratory Equipment
- Test tubes are hollow glass cylinders used for experiments containing one closed end.
- Crucible tongs are specialized tongs designed to handle hot crucibles.
- Beaker tongs allow for safe transport of heated beakers.
- Test tube holders securely hold test tubes during experiments.
- Pipettes measure out small liquid volumes with precision.
- Droppers dispense liquids drop by drop for controlled applications.
- Spatulas scoop chemical powders or solid samples for measurement.
- Triple beam balance is employed to measure the mass of objects accurately.
- Meter sticks measure the length of objects, providing precise dimensions.
- Thermometers gauge temperature with various scales (Celsius, Fahrenheit).
- Stir rods mix chemicals and liquids thoroughly in laboratory settings.
- Petri dishes serve as culture containers for microbiological growth.
- Evaporating dishes separate solids from liquid solutions through evaporation.
- Dissecting pans are designed to hold specimens during dissection activities.
- Dissecting kits contain tools necessary for performing dissections.
Biological Concepts
- Cells are the basic unit of life, classified into prokaryotes (single-celled, no nucleus) and eukaryotes (cells with a nucleus).
- Four major tissue types: nerve, muscle, epithelial, and connective tissues, each performing distinct functions.
- Organs are groups of tissues working together; examples include the liver, stomach, heart, and kidney.
- Organ systems consist of organs collaborating for specific functions, such as digestive and respiratory systems.
- Organisms can be unicellular or multicellular, encompassing all living creatures.
Cell Cycle and Mitosis
- The cell cycle includes growth, replication, and division, consisting of phases such as G1 (growth), S (synthesis), and G2 (preparation for division).
- M phase encompasses mitosis and meiosis, where cell division occurs.
- Cytokinesis is the division of the cytoplasm following karyokinesis (nuclei division).
- G1 phase involves cell growth and preparation for DNA synthesis, while S phase involves DNA replication.
- G2 phase synthesizes proteins crucial for cell division.
Protein Production
- DNA (deoxyribonucleic acid) carries hereditary information in organisms.
- RNA (ribonucleic acid) is involved in protein synthesis, including transcription and translation processes.
- Transcription copies genetic information from DNA to messenger RNA (mRNA) in the nucleus.
- Translation decodes mRNA into proteins, with tRNA transporting specific amino acids to ribosomes, where proteins are assembled.
- The codon chart provides the mapping of three-nucleotide sequences to their corresponding amino acids.
Additional Biological Terms
- Ecosystems consist of communities of organisms and their nonliving environments.
- Biomes are large areas with similar climates and ecological communities.
- Organ systems and communities function together to maintain life processes in ecosystems.
