What was the Green Revolution?
A period of significant agricultural advancements that dramatically increased food production.
What is NASA?
NASA is the National aeronautics and space administration, the US government agency responsible for space exploration, and aeronautics research.
What is the satellite imagery used for?
Weather monitoring, environmental studies, mapping, urban planning, agriculture monitoring, and military intelligence.
Explain the difference of a gene and a chromosome
A gene is a specific sequence of DNA that codes for a particular trait, a chromosome is a structure made of DNA that contains many genes.
Explain the difference between a Web browser and a search engine
A web browser is a software application that allows you to access websites, a search engine is a website that helps find information on the Internet.
What were the main technologies that were part of the green revolution?
The development of high-yielding varieties of crops, increased the use of fertilizers, and expanded irrigation systems.
What is the primary purpose of the International space station?
to serve a research laboratory in space, scientists and astronauts conduct experiments in micro gravity to advanced scientific knowledge.
How do GPS satellites help in determining the location on earth?
By using timing signals from multiple satellites to calculate distances and triangulate a position.
Describe the process of DNA replication
Starts with DNA double helix unwinding into two strands, enzymes add nucleotides to the new strand, following the base pairing rule.
Describe how data travels from a computer to a website browser
When data is sent, it is broken down into small packets, each packet contains the destination IP address. Once our packets arrive at the server, they are reassembled.
What are some of the positive impacts of the green revolution?
Increased food production, which helped to reduce famine and improve food security in some regions
What is the thermosphere?
The layer of earths atmosphere directly above the mesosphere and below the exosphere.
What type of orbit is commonly used for weather satellites?
Discuss the ethical considerations surrounding germaine gene editing in humans.
Changes in DNA that are heritable. Ethical concerns include the potential for unattended consequences.
What is the difference between IPu4 and IPu6?
IPu4 uses 32-bit addresses which allows 4.3 billion uniq addresses, IPu6 uses 128-bit addresses which allows for a vastly larger number of unique addresses (3.4 x 10 ^36)
What were some of the negative environmental impacts of the green revolution?
Increased use of chemical fertilizers and pesticides, increased the demand for water resources, leading to depletion in some areas.
What is microgravity?
The condition of experiencing very low gravity, close to weightlessness.
What are some challenges of maintaining and operating satellites in space?
Harsh environment, limited lifespan, communication, delays, power, limitations, space debris.
How do epigenetic modifications influence gene expression?
They influence gene expression without changing the underline DNA sequence. Modifications can affect chromatin structure.
Explain the concept of net neutrality
Net neutrality is the principle that all Internet traffic should be treated equally by Internet service providers.
Discuss the social and economic impacts of the green revolution
Often favored larger land owners who could afford the new technologies, leading to an increase in equality.
