Ecology : study of interactions between organisms and their environment Environment : all factors outside the organism; biotic and abiotic Proximal Patterns : can be explained by present environment (weather influencing plant growth) Ultimate Patterns : can be explained by past environment (ecological experiences of ancestors through evolution) Scientific Process : 1. Observation/Discovery 2. Question 3. Hypothesis 4. Test (observe, experiment, or mathematical modeling) 5. Conclus...

CBE 235 Final.Lac Operon - correct answer -involved in heating lactose: inducible operon 1) The lactose repressor protein coded by Lacl bound to the operator tightly near the mRNA start site, blocking the ability of RNA poly to bind 2) Lactose introduced--> Lac repressor binds to lactose and changes conformation such that it can no longer bond to the operator 3) RNA poly can access the promoter and transcription goes 4) LacZ,LacY,LacA are transcribed Gregor Mendel Experiment - correct ...

Ruderal A whole community can be ruderal. Can often remain stuck in fairly simple life history trait species. Potentially not great competitors. Tolerators of harsh conditions. Often early colonizers. Colonizer Moves to suitable unihabited (by another competitor species) habitat. Ex: PJ moving into ponderosa land due to drought. There can still be colonizers without disturbance. Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:15 Full screen...

Reasons why Mendel used pea plants Ans Hermaphrodites (can self fertilize & cross easily) and discrete phenotypes Fundamental thing Mendel did Ans Count, allowing for systemization True Breeding Strain Ans produces own phenotype Mendel's Law of Segregation Ans 1. One gene controls traits 2. 2 forms of a gene 3. Each individual has 2 alleles 4. Each parent contributes 1 allele 5. One allele is dominant to the other 6. Alleles separate equally to gametes 7. Games unite randomly 8. E...
