what does immunological tolerance create ~~> random generation of repertoire of BCR and TCR production of self reactive specificities types of TCR recognition due to random TCR gene rearrangement ~~> - can't recognise self-MHC (die) - recognise self MHC and p from Ag in thymus (+ve then eliminated by -ve selection) - self MHC and p not in thymus (+ve selection) what is TCR survival and tolerance based on ~~> TCR affinity need a pop of cells with medium affinity to self MHC...

Geomorphology - the science of landforms (their origin, form, and spatial distribution) Topography - elevation changes of the earth's surface over a given space or distance (ridges and valleys) Landform - an individual element of a landscape, mountain, or a valley, etc. Uniformitarianism - the idea that the processes of change we see today are the same as they were in the past and will be in the future. Types of landforms - tectonic, fluvial, karst, glacial, eolian, and coastal Tectoni...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...
