basics
What is biotechnology?
the use of living organisms or biological systems to create new products, processes, or services
gmo?
genetically modified organism
What are the main differences between traditional breeding and genetic engineering?
raditional breeding relies on selecting for desirable traits over generations, while genetic engineering directly modifies the plant's DNA
What are some benefits of using biotechnology in agriculture?
increased crop yields, reduced environmental impact, improved crop quality, enhanced food security,ect
whats the importance of scientific figures?
Everyone makes measurements. Making and using measurements is not limited to scientific research or to a science class. Everyone makes and uses measurements every day.
What are some examples of biotechnology in everyday life?
biofuels, vaccines, and genetically modified foods, ect
transgenics?
The study and practice of genetic modification by inserting genes from one species into the genetic material of another species. This can produce a new "designed" species
How is DNA used in biotechnology?
gene modification, protein production, and diagnostics
What are some examples of biotech-derived products you eat every day?
most gmo's
What is the difference between precision and accuracy?
ccuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close measurements of the same item are to each other
How is biotechnology used to produce insulin for diabetes treatment?
genetically engineering bacteria or yeast to produce human insulin, which is then harvested, purified, and used as medication
extinct species?
A species that has died out completely
What are some applications of DNA fingerprinting?
identify individuals, establish paternity, and diagnose inherited disorders
what is a bioreacter in biotechnology?
a device or vessel that provides a controlled environment for cultivating cells or microorganisms to produce specific substances
Scientific notation:195,000,000,000
1.95 x 1011
What are some ethical considerations of biotechnology?
voluntary participation, informed consent, anonymity, confidentiality, potential for harm,results communication, etc
DNA fingerprinting?
A technique for identifying individual organisms based upon the uniqueness of their DNA pattern. The technique has applications in forensics, paternity testing, anthropology, conservation biology and ecological research.
What is gene therapy and how does it work?
a technique that uses genes to treat, prevent, or cure diseases, often by replacing a defective gene with a healthy one or by modifying the expression of a specific gene
What is bioremediation and how is it used to clean up pollution?
a process that uses microorganisms, like bacteria and fungi, to clean up environmental pollution
Significant figure:27.8

How is biotechnology used in wastewater treatment?
utilizing biological processes, specifically microorganisms and plants, to degrade pollutants and remove nutrients from wastewater
genetically engineered foods
A substance that has foreign genes inserted into its genetic code. Genetic engineering can be done with plants, animals, or micro-organisms. Scientists can move desired genes from one plant into another, or even from an animal to a plant or vice versa.
What are some examples of recombinant DNA technologies?
producing human insulin in bacteria, creating gene therapies, and developing genetically modified organisms
How are bioplastics made and what are their advantages?
made from renewable resources like plants and algae, and can be biodegradable or compostable
accuracy and precision: A student determines the density of iron to be 7.07 g/cm3. The true value for the density of copper is 7.874 g/cm3. What is the percentage error of the student’s measurement?
% Error = 7.07 – 7.874 x 100%
7.874
% Error = – 10.21 %
