Science

• Biodiversity means variety of life forms within an ecosystem.
• Population is a group of individuals that can breed
• mutualism both benefits
• Symbiosis is a symbiotic relationship
• Food web is a feeding relationship between different organisms
• Food chain is each organism is eaten by the next one in the chain
• Habitat is a specific place or environment
• Niche - a specific role or way of life
• Abiotic Limiting factors - consists of two - abiotic and biotic.
• THREATS TO BIODIVERSITY

  • Habitat Loss
  • Over Exploitation
  • Intro to new species
• Expotential Growth Model is a population that is increasing at a rapid and greater state than the birth rate
• Logistic Growth Model is a model that grows a population at a slower rate and has a limit capacity called Carrying Capacity
• Population Density is a measure of the number of people living per unit of area
• RNA means Ribonucleic Acid
• Ribonucleic Acid (RNA) is a polymer of nucleotides that is the primary molecule of genetic information in all cells
• Messenger RNA (mRNA) is a single stranded RNA molecule that carries the information from DNA to ribosomes
• Ribosomal RNA (rRNA) is a single stranded molecule that is used to synthesize proteins
• Transfer RNA (tRNA) carries amino acids to the ribosome
• Transcription is the process of copying the DNA into RNA, which is the first step in protein synthesis
• Translation is the process of converting the information in a gene into a sequence of amino acids.
• Evolution is the change in the inherited characteristics of a population over time.
• Mircro is a small change of a species
• Macro is a big change for a species or organism
