Letter to MLA

Dear BC MLA,

It has come to my attention the failures we have had in BC when it comes to LNG and we shouldn’t have it progress any further.

This can provide areas with an unsafe water supply that you cannot live on but are forced to adapt and find a way to live with it anyway.

“LNG is often regarded as extremely dangerous and toxic with container ships called floating bombs. But is this perception accurate? The historical reality is that LNG has the best safety record of all common fuel types and is completely non-toxic. Of course natural gas vapors are flammable and present safety hazards that must be managed, but these hazards are substantially less than for gasoline, diesel and other liquid fuels.”

How Dangerous is LNG?

““LNG is safe, on land and in transit as a result of detailed industry standards, strict regulations, and a commitment to risk management,” reads one government website. As the U.S. Congressional Research Service tidily noted in 2004, there have always been public concerns about the siting of LNG terminals because “LNG is a hazardous liquid transported and stored in enormous quantities, often near populated areas.””

“In fact, a recent and nasty explosion at an LNG facility in Washington State, combined with alarming British research on what scientists call “vapour cloud explosions” or the release of flammable gases into the atmosphere, has raised new doubts about the adequacy of safety regulations for siting LNG export terminals in North America.”


From what I see this is an unsafe approach and I would advise against it.


Thank You.

1. Sedimentary – Without the formation of sedimentary rock we wouldn’t have the great attraction sites of places like the grand canyon.

Igneous – without igneous rock we wouldn’t have granite which is useful for us as we use it
For decoration.

Metamorphic – we use metamorphic rock as roof tiles because it resists acidic weathering.

2. Both are by the cycling of matter of rock, magma, water, ice, gases and living things that remain. In the rock cycle, rocks and matter go through uplift, weathering, erosion, deposition, melting, crystallization and metamorphism as they travel between earths surface and its interior layers.

3. They are deposited by hydrothermal fluids. They are formed by sediments particles of rock material that have been transported to new locations. They are produced by the breaking down of rocks.

4. I would expect to find them mostly in the Canadian shield because of how large it is.

5. You are looking for when they have been squeezed out of source rocks and concentrated in traps or reservoirs because that is when the two minerals become economically useful as fossil fuels.

6. Metamorphic rocks change form based on the influence of heat, pressure, or chemical activity. Sedimentary rocks are essentially formed by pieces of smaller rocks, fossils, and sediments

7.BC – sedimentary and volcanic, intrusive, sedimentary
Alberta – sedimentary
Saskatchewan – sedimentary and volcanic, intrusive
Manitoba – Intrusive, sedimentary and volcanic
Ontario – sedimentary and volcanic, intrusive
Quebec – Intrusive
Newfoundland – sedimentary
New Brunswick- Volcanic
Nova Scotia – Volcanic
PEI – Volcanic

8. Rocks can affect politics and economics around the world in ways like diamonds and the affects they have on money.


1. Describe the process of translation: initiation, elongation, and termination.

Initiation – Happens when mRNA, tRNA and an amino acid meet up inside the ribosome. Once a stop codon reaches the ribosome translation stops.


Elongation – The ribosome delivers the message, reading codons and bringing in the proper aminoacyl tRNA’s to translate the message out to protein.


Termination – At a stop codon, a release factor reads the triplet, and polypeptide synthesis ends.

2. How did todays activity do a good job of modelling the process of translation? In what ways was our model inaccurate.

It helped us understand how it works and it was inaccurate because the A and P sites were to big.

RNA Transcription

How is mRNA different from DNA?

DNA is made up of deoxyribose sugar and mRNA is made up of ribose sugar.
DNA has thymine where as mRNA has uracil.
DNA is in the nucleus and mRNA diffuses into the cytoplasm.

2. Describe the process of transcription.

DNA is copied into mRNA which carries the information to perform protein synthesis.
3. How did todays activity do a good job of modelling the process of RNA transcription. In what ways was our model inaccurate.

It show how mRNA comes and attaches to the DNA to copy the information and then leaves and the DNA zips back up again once it leaves. RNA preliminary comes in and unzips the DNA then takes the information then releases itself and the DNA zips back up. Then RNA does its thing. Its so fast that you cant see it happen.


DNA Replication

When does DNA replication occur?

Occurs prior to cell division, and is a semiconservative process.

2. Name and describe the 3 steps involved in DNA replication. Why does the process occur differently on the leading and lagging strands.

Unwinding – The unzipping of the double helix structure.

Complimentary base pairing – A pairs with T and C pairs with G

Joining – Ligase is like glue, it joins all the nucleotides together to create a strand.

The difference between leading and lagging is, Leading is continuous as the DNA unzips and Lagging is Fragments form as the DNA unzips.


3, The model today wasn’t a great fit for the process we are exploring. What did you do to model the complimentary base pairing and joining of adjacent nucleotides steps of DNA replication. In What ways was this activity well suited to joining this process? In what ways was it inaccurate.

To model the complimentary base pairing we used colour beads where each colour referred to ATCG.

This was well suited for the joining process because it shows the hydrogen bonds (white) and where they all connect together.
