  • there is now ample DNA to coat gold particles that are shot into the seed of plant cells
  • Antibiotic resistance is an indicator that the bacteria has incorporated the desired trait.
  • can then be grown with the new desired trait as part of its genom
  • A bacteria called Agrobacterium tumafaciens then incorporates this DNA and creates copies of itself
  • inserted into a circular piece of DNA called a plasmid
  • the DNA sequence for the desired trait must be identified, isolated, and cut from its original source
  • then cured by exposure to heat and light, and the model solidifies
  • the excess resin is drained from the model
  • the laser cures the second layer of the model on top of the first layer
  • the elevator lowers the platform vertically by a small amount
  • resin’s adhesive properties
  • the laser moves horizontally across the x-axis and y-axis
  • which means that it will solidify when a laser hits the surface of the resin
  • A vat is filled with photocurable resin
  • stereolithography apparatus
  • After the model has been designed, a computer is connected to an SLA
  • solidified by the laser will fall out of place
  • be oriented to minimize unsupported surfaces
  • first develop a model on a CAD system
  • EEG (electroencephalography)
  • The function of an EEG is to monitor and record electrical activity in the brain
  • poor sleep patterns are linked to increased chance of disease
  • disposes of it through lymphatic ducts
  • opening the membrane of the glial cells
  • by flushing the metabolic waste out of the brain cells with cerebrospinal fluid (CSF)
  • metabolic byproduct
  • beta amyloid proteins
  • If this waste is not disposed of, it can become pathogenic
  • toxic metabolic waste
  • The brain creates energy through the metabolic process
  • non-neuronal cells
  • neurons, and glia
  • its shorter wavelengths are more directional than longer wavelengths
  • is limited by line-of-sight
  • makes it difficult for rural areas
  • infrastructure development
  • low population density
  • located in buildings and on street lamps
  • macrocells”, which have a wide area of coverage
  • 5G signal is broadcast by small cells
  • speed, measured as peak data rate
  • in one month, there is enough data flowing through the 5G network to fill over 1 million 1TB hard drives
  • amounting to an estimated 50 Exabytes per month in 2021
  • enables ultra-reliable applications of network technology
  • control of heavy machinery
  • remote surgery
  • which means it take 10 ms for one device to send data to another
  • enabling much faster communication between devices
  • Latency is the response time between two devices
  • a law is a description of observable phenomena
  • a theory is an explanation based on extensive evidence
  • It’s applicability is constantly tested
  • a theory is not indisputable
  • result of consensus among scientists
  • a theory has been testes and supported by many experiments in various situations
  • difference
  • the hypothesis may turn into a theory
  • hypothesis seems incontrovertible
  • after repeated testing
  • results support the hypothesis
  • go back and revise
  • either support or not support
  • exclude any subjective bias
  • allow the scientist to make objective conclusions
  • After the hypothesis has been formulated
  • able to be tested and measured reliably
  • based on those facts
  • test the hypothesis in an experiment
  • must meet a high standard of rigor
  • formulate a hypothesis
  • Facts are stated observations
  • gathers all observable facts
  • formulates a question they would like to investigate
