Biology And Its Theme: Cap 1 Flashcards
The biosphere
All live om Earth, a global ecosystem of the biotic and abiotic factors
Ecosystem
Living organism in a particular area
Communities
An interacting group of different species in the same area
Population
Consist of all the inviduals of a species living within the bounds of a specified area that interbreed with each other
Organism
Invidual living things
Emergent properties
A complex system, not the invidual parts
Systems biology
The exploration of biological system by analyzing the interaction among its parts
Prokaryotic cells
Lacks a nucleus and membrane enclosed organelles. Bacteria and archaea
Eukaryote cells
Contains membrane enclosed organelles. Plants and animals
Genes
A section of the DNA of the chromosome. Cooking books of the proteins.
Dubble helix
Double strand of DNA
Nucleotides
Chemical building blocks: A,T,C,G
Gene expression
The entire process by which the information in a gene directs the manufacture of a cellular product
- transcription (split in half mRNA)
- translation (making a protein)
- protein folding
Genome
The entire library of genetic construction that an organism inherits
Producer
Produce chemical energy (plants)
Consumers
Feeds on other organism or their remains (human, worms)
Feedbacks regulation
Output or product of a process that regulates the very process.
- negative feedback. (Reduces the initial stimulus) insulin
- positive feedback (end product speeds up its own production)
Climate change
A directional change to the global climate that last longer than three decades
-extreme weathers
The three domains of life
Bacteria, Archea and eukarya.
-(four subgroups of eukarya: kingdom plantae, kingdom fungi, kingdom animalia and protist)
Decent with modification
Accumulate differences from their ancestors
Prototype mammals
Mammals from which all others mammals descended
Inquiry
The search for information and explanation of natural phenomena
Independent variable
The factor being manipulated
Dependent variable
The factor being measured that is predicted to be affected by the independent variable
