What is physiology? Study of how organisms, organs, cells, and biomolecules carry out the chemical or physical functions in an organism What is ecology? A holistic way of viewing nature in order to comprehend how those tangled ecosystems work by following and studying connections between all living and non living things Physiological ecology? How organisms function in their environment Dynamic process: evolution is ongoing Natural selection (benefit)? a process whereby an individual organism...

BIOL 2300 Midterm 1 Latest Update Graded A+ 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, experi...

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The formation of new species in populations that are geographically isolated from one another. allopolyploidy - a species with multiple sets of chromosomes derived from different species Alpha (origination...
