Thomas asks…
How can I cycle my paper?
This paper would be cycled for the first time, and presumably recycled later. I found a recycling center for it, but not a cycling center.
The Expert answers:
I think you might have to get a paid subscription to the daily schwin, and read the op-ed piece about ‘cranks and pumps’. I could be wrong, it’s been a long time since that one balled lance has won the Tour de France.
Lizzie asks…
What is one way in which energy flow differs from chemical cycling?
a) Energy can enter but cannot leave an ecosystem; chemical elements can leave but cannot enter an ecosystem.
b) Energy flows from lower to higher trophic levels; chemicals cycle from higher to lower trophic levels.
c) Energy flow is unidirectional; chemical elements can be recycled.
The Expert answers:
C) Energy flow is unidirectional; chemical elements can be recycled.
Paul asks…
Why is the citric acid cycle called a cycle?
a. The pyruvate that enters the cycle is regenerated in the last step of the pathway.
b. NAD+ and FAD are recycled.
c. The four-carbon acid that accepts the acetyl CoA in the first step of the cycle is regenerated by the last step of the cycle.
d. All of the carbon from glucose is cycled back into the atmosphere as carbon dioxide.
NADH is cycled down the electron transport chain.
The Expert answers:
It is designated as a “cycle” as it is a iterative process essential for the maintenance of the organelle.
Maria asks…
major reasons for recycling and cycling elements and compounds is to do what?
The Expert answers:
What are the major reasons for recycling certain materials?
Recycling is an easy way to reprocess materials. Recycling typically is done at a fraction of the cost of processing raw materials. Recycling is a good alternative to using up land for dumping purposes. Recycling cuts down on trash since people can make money from other people’s trash.
John asks…
Is there any new carbon in out atmosphere?
Does the carbon cycle just continue to recycle. Is it like the water cycle where its the same water being continuously cycled around?
The Expert answers:
Yes it does continue to cycle but the carbon released from burning fossil fuels is part of a very long carbon cycle in that it takes millions of years for the carbon to slowly form fossil reserves and even longer for it to be naturally released. We’ve been burning millions of years worth in just a few short decades thereby moving all of the carbon from a large part of a very large cycle to a very small part of the cycle
Joseph asks…
Which is more “eco-friendly” – handwashing dishes or running the dishwasher?
With hand washing, it is water and soap but probably more water than the dishwasher. However, the dishwasher took energy and resources to create, uses electricity every time and will need to be broken down to be recycled after it’s life cycle.
The Expert answers:
Paper plates
Lisa asks…
How should i go about changing my substrate?
I have a 35 Gallon cycled tank with 4 medium angels and 3 2 inch clown loaches…I would like to switch from my gravel to a more suitable sand subsrate. So i am curious on how i should do this. Should i put them in a temporary home until its all changed and recycled? Or would it not need to recycle?
The Expert answers:
Get a few clean 5 gallon buckets and save as much of the existing, cycled water from your tank as you can. Use one or two of those to keep you fish in until you’re finished (you could use an airpump and stone if you’re going to take a while). Then just dump the old and replace it with the new, pre-washed substrate. Then just refill your tank with the cycled water and gently put your fish back into the tank. There will be plenty of bacteria left in your filter and on the other surfaces of your tank. Your fish will hardly know anything has happened.
