Answer:
Epidemiological Study
Explanation:
This type of study is called and epidemiological study. The design of this study uses a group or individual that have been exposed or not been exposed to a certain condition. The parameters will account for similar age, sex working habits etc. This will correctly identify if the contributing factor is the exposure of the agent or otherwise.
Once a seller spikes the prices of goods, services or commodities to a level much higher than is considered reasonable or fair, it is called Price gouging and is considered unfair, possibly to an unprincipled level. This laws are types of rice ceilings and often result in shortages of a scarce good.
The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
<span>In photosystem II, which is actually the first of the light reactions, H2O is an an input, and split. The H electrons and protons are used by the plant to create ATP for the Calvin cycle. As for the O2 molecules, they are released by the plant as waste. Which is good for us living organisms that require O2, which is required as the terminal electron acceptor at the very end of cellular respiration. The O2 that plants release into the atmosphere, is breathed in by us, and that is how it enters our body.
So the sugar from plants provides us chemical energy (we break it down over several steps and take the free energy to produce ATP).
The final step of cellular respiration, which is electron transport and oxidative phosphorylation requires those O's we inhaled, because it accepts electrons from NADH and FADH (which are both carriers of electrons from the glucose that has been broken down), and by accepting the electrons allows for H protons to enter the ATP synthase protein which phosphorylates ADP + Pi (inorganic phosphate) into ATP. This yields I believe 32-34 ATPs, by far the biggest energy making component of respiration. Those H protons that were used for oxidative phosphoylation then react with the Os and leave our body as H2O.
So in short, the products of photosynthesis that living organisms use are glucose and oxygen. The oxygen is crucial for organisms that use aerobic respiration (aerobic meaning they need O2).
I also forgot to mention CO2. CO2 enters the plant at the beginning of the Calvin Cycle. The plant uses carbon fixation, in which it basically takes inorganic CO2 from the air, and makes (fixes) it into an organic compound, glucose. This is actually how the plant obtains its biomass.
Anyway, without plants, our atmosphere would contain far too much CO2 to sustain life on earth. Think of Venus. It would act as a thick blanket that would retain all of the sun's heat, causing a runaway greenhouse effect.</span>
