Homeostasisb. Positive and negative feedbackCurrent LectureCheck LaunchPad for the case study informationOomycetes- Water molds, white rusts and downy mildewso Decomposers and parasites of plants and animals- Historically considered fungiWhat makes an animal an animal?- Eukaryotic cells- Multicellularity/ specialized cells- Heterotrophs- Sexual reproduction- Energy processors- Cleavage (during development)- O2 respiration- Sensory system- Collagen/ integrinPlants vs. animalsSimilarities:These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Specialized cells - Diploid generation - Cellular respiration- Mitosis and meiosis- Hormones- Defense system- MotilityDifferences:- Autotrophs vs. heterotrophs- Alternation of generations- Cell walls- Indeterminant vs. determinant- Primary producers vs. consumers- Nervous systems- Cell to cell communications- Cell structureNon-biological feedback loops- Cruise control- Flush mechanism- Stock market- A springBiological feedback - Human body temperature- thermoregulation- Metabolism- Regulation of body sugar- Insulin/ glucagenHomeostasis- Stimulus sensor control effecterNegative feedbacks are usually seen in a loop fashionCommon positive feedbacks are labor and blood
