A placebo is basically an alternative medical treatment (e.g. pill)  that doesn't <span>contain an active substance meant to affect health. So it isn't actually solving anything but it can have the placebo effect. Which can be assumed is the reason it is sometimes used in experiments. </span>

A placebo is kind of a "fake" treatment but, typically the person receiving a placebo is unaware it has no medical effect on them so they believe they are feeling better. For example, a lot of anxiety meds are placebos and people don't know so their brain tricks them into thinking they are feeling less anxious. This could be used in experiments where a group believes they are affected to see how they react

The phylogenetic distribution of the enzyme rubisco is limited to
Dmitry_Shevchenko [17]
<h2>The phylogenetic distribution of the enzyme RuBisCo is limited to all photoautotrophs, both bacterial and eukaryotic. </h2>

Explanation:

  • This is because the  RuBisCo mechanism takes place in all photoautotrophs and fixes inorganic CO2 into organic biomass or the biosphere through the Calvin Cycle of photosynthesis.
  • The D-Ribulose-1, 5-Biphosphate Carboxylase-Oxygenase or RuBisCo is a catalytic enzyme that plays a crucial part in photosynthesis through carbon fixation by photoautotrophs including bacteria and eukaryotes.
  • The RuBisCo takes part in photosynthesis especially in Calvin Cycle during fixation of carbon from carbon dioxide to D-Ribulose.
  • Since it is a photosynthetic enzyme, it is present in photoautotrophs .
