ch1.
a. Levels of organization of life: Subatomic particles- atomic particles- organelles - cell - tissue- organ- organ system- organism- family- population- ecosystem- biosphere.
b. All life forms are based on similar fundamental organization i.e. genetic information in the form of DNA, transcribed to RNA and translated to proteins.
c. Evolution results in a vast number of different adaptations for survival and reproduction. L ife exists in many different forms in soil and on the surface of land, in water and in air.
d. Before life was classified into two kingdoms: Plant kingdom and Animal kingdom.
Later R.H. Whittaker classified into five kingdoms: Monera, Protista, Plantae, Fungi, Animalia.
e. Thinking in scientific way is the best vehicle for obtaining knowledge. The skills - observe, compare, sort and organize, predict, experiment, evaluate and apply are the seven essential steps of scientific thinking.
f. Steps: 1. Anticipate necessary time and items.
2. Create thorough tables and checklists
3. Systematize your tubes
4. Proceed consistently to aid efficiency
g. first review your data, calculate average of your different trial experiments, label all tables and graphs, draw conclusions and make recommendations.
f. Science is definitely not a list of facts, it is a method of investigation. A specific science like biology or physics has a structure of concepts based on the work of several scientists.
