Joseph asks…
is the recycled water of the water cycle clean?
The Expert answers:
The water in the ‘water cycle’ begins over the ocean, where the heat of the sun causes water vapor to rise into the sky, where it later falls as rain…… Water vapor is pure…. When it becomes rain, it may have a dab of dust in it….. If the rain falls thru polluted air, it may pick up some of the pollutants… So not all rain water is good to drink….. But once it hits Earth and gets filtered by the soil , down into aquifers, it’s pretty clean at that point….. Water that becomes runoff from rain picks up some icky stuff from the streets, down the sewers, to the rivers, etc….. So, yes, it starts out clean…..

what molecule is recycled in the citric acid cycle?
The Expert answers:
Oxaloacetate

I want to find a battery charger that recycles through a discharge/charge cycle to prolong its life?
As an oldie I am finding my vehicle batteries fail prematurely because of lack of use – I need a device that cycles a battery through charge/discharge and thus prevent sulphation and overcharging
The Expert answers:
If you use a “trickle charger” on your battery, It will maintain a charge (you can get ones that run from sunlight.) Discharging and recharging a modern car battery will destroy it. Today’s car battery’s do not need water added, “sulphation” too be checked or anything else to be done except maintain there charge. The only battery’s that benefit from a discharge cycle are deep cycle battery’s that are usually used for marine applications.
Paul asks…
Because the water cycle recycles fresh water at a relatively slow pace, water is considered a nonrenewable ?
The Expert answers:
Water can be considered a renewable material (also non-renewable) when carefully controlled usage, treatment, and release are followed. If not, it would become a non-renewable resource at that location. For example, groundwater could be removed from an aquifer at a rate greater than the sustainable recharge. Removal of water from the pore spaces may cause permanent compaction (subsidence) that cannot be renewed.
Charles asks…
Which of the following is NOT true about matter in the biosphere?
Which of the following is NOT true about matter in the biosphere?
[a] matter is recycled in the biosphere
[b] biogeochemical cycles transform and reuse molecules
[c] the total amount of matter decreases over time
[d] water and nutrients pass between organisms and the environment
[e] the lack of a specific nutrient can reduce primary productivity
Thanks in advance 🙂
Vanessa.
The Expert answers:
When you say biosphere, are you referring to earth? Because earth is not shrinking, the resources are being transformed into useless molecules. I would go with B.
Steven asks…
Is death the natural cycle of food chain and recycle of resource?
Or it was not the original design of the Creator. Death change the original Creator design and only exist after sin and transgression of the Creator laws as justice demand?
Was the original Creator design of life is eternal youth and eternal life for man existence?
Will this be restored to man once again after sin is eradicated?
Will death, the final enemy will be no more for eternity?
The Expert answers:
Death is only an enemy to those who would fear it, and who would choose an undying eternal tortuous existence out of ignorance.
Death is only natural, and much preferable to immortality.
Mark asks…
Describe how the carbon cycle relates to the carbonate reactions in this investigation.?
This is an extra credit question for my chemistry class.
Earth’s long-term carbon cycle involves the recycling of carbon through the ecosystems over thousands of years. Many scientists believe that the cycling of carbon from carbonate rock to the atmosphere was an important factor in the development of Earth’s climate. Investigate the long-term carbon cycle and its role in maintaining Earth’s climate. Describe how the carbon cycle relates to the carbonate reactions in this investigation.
The Expert answers:
You should look up in library not here
Sharon asks…
summarize the production of ATP for each of the three stages in aerobic respiration. how is ATP recycled?
i know that there is 4 stages but we dont need the stage between gylcolysis and the kreb’s cycle, just those two and the electron transport chain
The Expert answers:
Oh k
here we go!
1. Glycolysis (in the cytoplasm)- you cut cluces into 2 pyruvates which are 2 3-carbon molecules, while that happens you reduce 2 NAD+ to 2 NADH and 2 ADP to reduce to 2 ATP
———since you dont need to know the prep rxn…lets skip it and saythat you made the acetyl CoA 2-carbon molecule
2.Krebs cycle (in mitochondria)- CO2 is produces but you yield 2 ATP, 6 NADH, and 2 FADH2
3.ETC or oxidative phosphorlyation (in the inner mitocondrial membrane)- NADH and FADH2 pass electrons down the chained until O2 is the final electron acceptor to make H2O; with that you produce alot of ATP, sorry dont know how much for sure
hope this helps with the numbers
i am pretty sure they are correct or close
David asks…
Which of the following is NOT a function of PGAL in plants?
A. it is used to produce ATP
B. it can be converted to glucose
C. it is recycled in the Calvin cycle
D. it can be changed into lipids
The Expert answers:
A. It is used to produce ATP – not correct.
B. It can be converted to glucose – correct
C. It is recycled in the Calvin cycle – correct – is used to regenerate the 5C acceptor (RuBP)
D. It can be changed into lipids – correct – can be converted to glycerol (a component of lipids).
