order
response to environment
evolutionary adaptation

emergent properties
interaction between organisms and with environment
necessity of energy transfer/transformation
form fits function
cell is the basic unit of life
life continues through DNA
feedback mechanisms regulate biological systems

What is genomics? What three developments make this possible?

genomics is the study of/analysis of the genome of an organism.

technological tools such as DNA sequencing
bioinformatics
interdisciplinary research

4

What are positive and negative feedback?

positive feedback- end product speeds up its own production
negative feedback- end product accumulation slows down production

5

What are the 8 taxonomic categories of life (in order from smallest to largest)?

species, genus, family, order, class, phylum, kingdom, domain

6

What are the three domains?

bacteria, archaea and eukarya

7

What are the kingdoms?

animalia, plantae, protists and fungi- eukarya
bacteria, archaea- prokarya

8

Discern between plantae, fungi, animals and protists.

Plants produce their own food by photosynthesis.
Animals ingest food.
Fungi absorb dissolved nutrients from their surroundings(often from decomposition).
Protists are single celled.
