Griffith college Tri1 202334 [WEEK12] Vertebrate and Human evolution Understand that the first chordates, from which vertebrates later evolved, arose in the Cambrian Explosion, ~ 500 MYA. 1) lancelet -> with notochord, tail, pharyngeal slits and hollow nerve cord 2) hag fish -> having head (ear, eyes, nasal opening and brain) BUT now jaws and vertebrate 3) lampreys -> earliest vertebrate, it has no jaws With jaws -> sharks and rays 4) tiktaalik -> fish and amphib.. 2023. 5. 28. [WEEK12] The Chemistry of Medicine ORIGINS OF DRUGS Plants and plant derivatives are the major sources of drugs. NOTE: (Infographics shown below as examples and for your interest only - not examinable) Plant-based drugs account for approximately 30% of all pharmaceuticals. A number of medicines (including tablets, injections, capsules, creams, mixtures and vaccines) contain animal products or are animal derived. Microbial product.. 2023. 5. 27. [WEEK12] The Chemistry of Exercise -ATP is the energy currency of the cell -Dephosphorylation of ATP (removal of P) releases energy -ATP is produced by cells by breaking down the food we eat in a process known as cellular respiration -Muscles utilise ATP to power contraction through Actin-Myosin cross bridge recycling -> FOR MUSCLE CONTRACTION , ATP is used as an ENERGY SOURCE -> ATP is produced by CELLULAR RESPIRATION < FUELS of.. 2023. 5. 26. [WEEK11] Evolution of Populations and Speciation Genetic diversity is dependent on population size; understand how the example of facial tumours in Tasmanian Devils illustrates this. When the population size is too small, it has less vairability in indiviuals gene, which means that it has less source to be natural selected. Large enough population is required for having a chance for more fitted individual existing. For example, tasmanian devil.. 2023. 5. 23. 이전 1 2 3 4 ··· 9 다음 반응형
