MOCA: Science Latest Update with Verified Solutions

MOCA: Science Latest Update with Verified Solutions Earth Science - A branch of scientific study about the planet we live on - Includes geology, the weather, the ocean, biomes, the environment, and more. Life Science - Involve the scientific study of living organisms - Ex: microorganisms, plants, animals, and human beings Physical Science - Study of non-living systems - Involves the study of matter and its motion through space and time, along with related concepts such as energy and force Life Cycle - The continuous sequence of changes of an organism from birth to adult Metamorphosis - A change of form from one stage to the next in the life cycle of an organism Prokaryotes - Single cellular organism - Cells do not contain a defined nucleus - Microorganisms that are typically encountered - Ex: E.Coli Archaebacteria - Single cellular organism - Cells do not contain a defined nucleus - Often called extreme bacteria and live in places where life is not expected to be found - Ex: Thermophiles Eukaryotes - Can be single or multicellular - Have a defined nucleus where the DNA is separated from the cell cytoplasm - Includes all animals, plants, fungi, and protist 3 domains of living things 1. Prokaryotes 2. Eukaryotes 3. Archaebacteria 6 kingdoms of living things 1. Animal 2. Plant 3. Fungi 4. Protist 5. Eubacteria 6. Archaebacteria Taxonomic Hierarchy - The process of sorting organisms based on their physical features - Domain is the most general level - Species is the most specific level 13 Eukaryotic cell organelles 1. Chloroplast 2. Mitochondria 3. Cytoplasm 4. Nucleus 5. Endoplasmic reticulum 6. Plasma Membrane 7. Ribosome 8. Golgi complex 9. Vesicles 10. Cell Wall 11. Centrioles 12. Lysomes 13. Cytoskeleton Chloroplast - Found in plants - Where sugars are made in photosynthesis Mitochondria - The power plant of the cell - Where cellular respiration occurs Cytoplasm - The liquid that allows for movement outside the cell Nucleus - Where DNA is held, the instructions on what to do Endoplasmic Reticulum - Where proteins and fats are made Plasma Membrane - The type of cellular barrier found in
