Negative feedback it reduce the effect on the body like blood sugar and body temperature Positive feedback it enhance the stimulus like labor contraction blood clotting Superior towards the head Inferior away from the head also called caudal Anterior towards the front of the body also called ventral Posterior dorsal towards thhe back of the body Medial towards the middle line of the body Lateral away from the midline biology Page 1 Week 2 Tuesday, August 27, 2024 8:24 AM Chemistry Week 2 Audio recording started: at 8:33 AM on Tuesday, August 27, 2024 Energy capacity to do work 4e types of energy Chemical energy Mechanical energy Electrical energy Electromagnetic energy 1st law of thermodynamics is that energy can neither be created nor destroyed but can converted D2O is an isotope, it used in tracking excretion and also used in carbon dating Radioisotopes same chemical formula but different structural formula Used as staining which is used in imaging Water is very cohesive because of the hydrogen bond REDOX Osmolarity molarconc Osmolarity massconc Con't Anything that has carbon is organic Monosaccharide glucose-fructose, galactose Disaccharides sucrose lactose maltose Polysaccharides glycogen starch and cellulose Function energy storage Insulation Protection for organs *phospholipids, steriods Week 2 Audio recording started: 8:45 AM on Thursday, August 29, 2024 A and T , C and G Importance of water Universal solvent High capacity for heat High vaporization point High reactive Provide cushion to the brain ( it might cause trama) PH potential of Hydrogen biology Page 2 PH potential of Hydrogen Buffer anything that converts strong acids/strong into weaker ones Prevent large rapids swing in PH Phospholipids the head is polar and hydrophilic [attracted to water biology Page 3 Cell Tuesday, September 3, 2024 8:21 AM Cell theory: the smallest unit of life All organisms are made up a cell Cell can only arise from other cells * Principle of complementary 3 Basic components Plasma membrane Cytoplasm Nucleus Study the structure of extracellular material 3 extracellular fluid - Blood plasma - Intersifia fluid Chas solutes] - Cerebrospinal fluid Cellular Secretion [Saliva, mucus, gastric juice ] matrix cellular known as a glue [most abundant material] Plasma membrane (Cell membrane] Phospholipids Glycolipids Chlolorestol it make sure it is stable Plasma membrane is selectively permeable two methods -.passive no energy, diffusion, osmosis 3 types Simple facilitated differs via carrier or channel protein, leakage handed, aquaporins e-g water, gated requires a stimulus osmosis – active AT require_ Na K pumps Vesicular transport Endocytosis Exocytosis (into plasm > I Cystosal get like solution Organelles Endoplasmic rectiluim mitochondria Write my own notes on this Golgi apparatus Cell Ribosome Lysosomes Interphase Subdiviison A and G C and T Prophase chromatin condenses and form chromosome. Metaphase chromosome aligns on the equato..RNA: Copies DNA code and sends it to Ribosome then endoplasmic reticular biology Page 4..RNA: Copies DNA code and sends it to Ribosome then endoplasmic reticular three types I MRNA copies DNA strand RRNA forms ribosome along other protein TRNA: carry Amin0 acid. Rate of cell division Hyperplasia fast.\ Atrophy: slow growth Telomer * help protect ends of chromosome biology Page 5  tissues Tuesday, September 10, 2024 8:24 AM types of tissue Epithelial tissue: function protection, absorption, filtration, excretion, secretion, sensory reception special parts: polarity, have a top Cspicad] & a bottom [basal] surface specialized contacts supported by connective tissue avascular but Innervated Regeneration Classes of Epithelia 1. 11 have two names. first name = cell layer - stratified = 2 layers thick Second name Connective tissue makeup Ground substance Fibers Cells biology Page 6 ☺ biology Page 7
