Lecture Number One Flashcards
Order
All living thing consist of one or more cells with highly ordered structures
Internal order within the species
Grow and develop
Increase of size and mass
Number of cells increase - duplication
Energy utilization
To maintain order, living things need energy
Process known as metabolism
Plants are the most important organism with transformaing energy
Regulation
Homeostasis
Self correcting internal envrionment
Keeps the body fucntioning
Must be maintained to live
Stimulis
Fluctuations above a set point (temp)
Stimulus are detected and trigger the body to respond
Reprodcution
Creating new offspring
Asexual reproduction
Can reproduce without another individual
Sexual reproduction
Creates new offspring that have genetic material from two different membersw
Evolution
Need to adapt to changes in te environment
Through evolution processes
Two mechanisms of evoltionary chnage
Vertical descent
Horizontal gene transfer
Vertical descent
Changes in lineage
New species evolve by mutations
Natural selection
Horizontal gene transfer
Exchnage between different species
