Biotic- living part of environment
Aboitic- not living air water/ climate
LEvels of organistion
Species
Population
Commmunty collection of interaction population
Ecosystem bio and abio factors
Habit were you live
Niche living in same tree different positions
predator / prey relationship predator are carnivores and omnivores and dependent on each other
Symbiosis
-comensalism one species plus zero doesnt get anything good or bad
Mutualims plus plus ant
Parasitism parasite beliefs other is harmed
Vocab autortroph food from self Heretrophs- consumer different place gets there food
Herbivor
Carnivore
Scaventgers clean up crew
Decomperser break down dead reclyers
Food chain/ patterns of flow energy flowws grass -mouse - owl
Food webs pay attention to arrows
Energy pyramids show relative amount ofenergy avalbine at each trophil levels
Limiting factors bio abio
Primary succession stages of the environment
Carrying capacity a number of organism of 1 species the environment can support
Biodiversity - the variety of life in an area
Trophich regions
Biger is better high biodiversity = stable ecosystem
Low biodiversity = less stable ecosystem
Threats to biodiversity Habitat loss
global warming increases in global temperature due to atmospheric co2 levels
Pollution and overpopulation
Causes using gases fossil fuels
Alternative energy sources - solar panel wind terbindes hydroelectric nuclear geothemeral
BIOCHEMISTRY
Compound - composed of atoms of 2 or more differenrt element that are chemically combingsed - bonding occurs between atom when they reach stability
Covalent bonds- atom share electrons hydro ions share with each other
Ionic bonds - Transfer electrons between atoms
Diffusion - the movement of particles from where there's more to and lesser
Carbharate carbs simple sugars
Lipids fatty acids and glyserol
Protein -amino acids
Nucleic acids - made out of mecleotides
CELLS BIOLOGY
Cell types
Prokaryotes dont membrane small
Eurkaryotes lots of cells presemce of membrane bound in organelles
Cell membran regulates what goes in and out
Cell wall support and protection
Nucleus control center
Ribosomes makes protein
Lysosomes breaks things down
Golgi - modfird protein and lipid s
Vacuoles stores things water nutruins ions
Chloroplast make energy from sunlight
Mitochondria make energy from carbs
Plant cells vs animals cells
Plant cells have cell walls animals dont
Plant cells have Chloroplast animal s
Plant cell has a central vacuum
Animals have centrio
Osmosis - movement of water to where is was more to were it was less going into
Mitosis 2 daughter cells are formed each identical to the original entire cell splits Sytokinesus division of the cell / splits in half
Organizaiton cont small to big
Cancer cells uncontrolled cell division MEDELIAN GENTICS AND MEIOSIS
Traits - characteristic heigh flower color seed texture
Phenotype - physical appearance
Genotype genetic makeup e
Alleles from of a gene for a trait
dominant allele always expressed T tall
recessive allele t short
Homozygous 2 of the same alles
Heterozygous has different alleles
Rule of dominance dominant allele is always expressed recessive allele insnt
Law of segetration pairs of alleles gamits separe when they fertilze each other
Law of independent assortment genes for different traits are inherited independently of each other
Meiosis type of cells divisions end up with four daughter cells which are different from each other
Diploid cell with 2 of each kind of chromosome
We have 46 cells
Haploid cells with 1 of each kind of chromosomes
crossing over exchange of genetic material between nonsister chromatids mixs up patterns of alleles
Pedigree chart square are male circles - female filled in - afflicted half filled - carrier
Genotype
-IaIa or Iai- type A
- IbIb or Ibi - type of B
- IaIb - type AB
- Ii-type O
Independent something you change
Dependent variable data what are you collecting time it take reaction to occur
