Calculate pH a decrease of one unit on the pH scale means a solution is ten times more acidic. a decrease of two units means the solution is 100 times more acidic. how much more acidic is acid precipitation( pH = 4.0) than pure water (PH= 7.0 )
Answer:
Each unit of decrease has an exponential increase. So if you are looking at an item that has a Ph of 4 and water has a Ph of 7 —-that means it is 10 to the 3rd power more acidic or 1000 times more acidic than water.
Explanation:
A decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.
What is the effect of pH on the cell?The pH scale shows the pH from 1 to 14, where pH 7 is taken as neutral, below which the solution is more acidic, and above which the solution is more basic. The pH has an important role in the organism as it regulates the blood and maintains enzymatic function.
Hence, a decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.

You learned about the aptly named enzyme Citrate Synthase. There are more enzymes that count citrate as substrate or product. Compare and contrast two reactions below that each split two carbons from citrate to make oxaloacetate. One catalyzed by the enzyme ATP Citrate Lyase and the second catalyzed by Citrate Lyase.
Acetyl-CoA
Citrate → ↑ → Oxaloacetate lyase
CoA-SH → ↑ ↑ ←ATP ↓→ ADP + Pi
ATP Citrate
Acetate
Citrate → ↑ ↓→ Oxaloacetate
Citrate lyase
Which of the following is an accurate statement about why ATP is required by ATP Citrate Lyase?
a) The hydrolysis of the thioester involving CoA-SH helps split ATP into ADP and Pi.
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
c) The Acetyl-CoA is pulled rapidly away to make lipids so the reaction needs extra energy to make it fast enough to keep up with demand.
d) The two carbons of acetate are more energetic than those on Acetyl-CoA and therefore don't need ATP to split them from citrate.
e) ATP is required to spit the two carbons from citrate.
Answer:
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
Explanation:
In the citrate cycle, we know that lysis is mediated by the hydrolysis of ATP, which is the fuel of the reaction, so the correct answer is B. The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.

When considering human impacts to ecosystems, identify the incorrect statement:
Select one:
a. cod, swordfish, halibut and mackerel populations are especially vulnerable to collapse
b. coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
c. aquaculture may provide a sustainable alternative for raising farmed fish to feed a growing human population, allowing ocean fisheries to recover
d. over half of global ocean fisheries populations have become severely overharvested within the past century
Answer:
coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
Explanation:
This is a wrong statement because coral reefs contrary to the statement is not recovering, Over-fishing an destructive fishing,(to meet up with increasing demand) are some of the human impacts reltively control by the enforcement.
But,acidification (eutrophication), and mass coral bleaching from global warming are not restricted by the enforcement of fishing quotas and are drastically reducing the population of the reefs.This in turn affecting the survival of the fishes, reducing the population,

Will change in ocean salinity cause a change in climate overall? Why or why not?
Answer:
Yes
Explanation:
Ocean play very important role in climate change. Change in the salinity of ocean definitely going to affect climate because changes in salinity have effect on water density.
Change in density allows changes in the movement of seawater and shift in climate pattern. if salinity will increase, water will become heavier and sink deep in ocean, which joins the currents that circulate all over the world. These currents affects the transport of heat and affect the rainfall pattern, example of such currents is gulf stream.
So, stable salt densities or salinity in the oceans keep the earth’s climate in balance.

What part of the fungus is seen in the woods or on the lawn? Please help I will mark you the branniest!
Damp conditions can bring out other types of fungi that can create more serious problems for your lawn. Brown patch, fusarium blight, and rust are a few of the diseases that thrive in wet grass.
Polypores are also called bracket fungi, and their woody fruiting bodies are called conks. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and their relatives corticioid fungi are the most important agents of wood decay.

Nadeau et al., (Royal Soc. B. 2007) Reconstructed dN/dS ratios for genes involved in sexually dimorphic plumage in pigeons and their relatives.
i. Let’s imagine that Nadeau et al., tested 5 genes, and got the followingdN/dS ratios:
gene1: 0.01
gene2: 0.05
gene 3: 0.90
gene 4: 1.01
gene 5: 2.34
Which gene has a dN/dS ratio that provides the strongest evidence of negative (‘purifying’) selection?
Answer:
The correct option is gene 1 with the dN/dS ratio of 0.01
Explanation:
In order for negative selection to occur, the dN/dS ratio has to be between 0 and 1. There three genes that lie within this range, and hence, we can choose the smallest one to provide the strongest evidence among those to represented as the one being negatively selected. Where the dN/dS ratio is equal to 1, it means neutral and where the dN/dS ratio is greater than 1, it means positive selection.
Hope that answers the question, have a great day!
