Answer:
long-term carbon; short-term carbon
Explanation:
The long-term carbon cycle, which takes millions of years, involves geological processes and carbon reserves that bury organic matter and exchange of carbon with rocks as well as formation of fossil fuels. On the other hand, short-term carbon cycle involves biological processes such as exchange of carbon dioxide between the sea and the atmosphere, photosynthesis, respiration, which occur within shorter periods.
Humans are indeed still evolving, the way how we are evolving nowadays has changed slightly compared to how we would have been evolving had we not developed cities and the modern way of life and how we live. There are always adaptations going on and different selective pressures as well.
Answer:
The answer to your question is V2 = 0.92 l
Explanation:
Data
Volume 1 = V1 = 2.4 l
Pressure 1 = P1 = 1.5 atm
Temperature 1 = T1 = 273 °C
Volume 2 = V2 = ?
Pressure 2 = 4.5 atm
Temperature 2 = 313 °K
Process
To solve this problem use the Combined gas law
P1V1/T1 = P2V2/T2
-Solve for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (1.5 x 2.4 x 313) / (273 x 4.5)
-Simplification
V2 = 1126.8 / 1228.5
-Result
V2 = 0.92 l
The statement that explains why randomized controlled trials are often "double blind" is as follows: to decrease bias by ensuring both the participants and researchers do not know who is receiving the treatment and who is not (option B).
<h3>What is a double blinded experiment?</h3>
Double-blinded experiments are forms of scientific testing in which some information is withheld from two different parties.
In summary, neither the tester nor the subjects tested know which are the control items and which are the test items.
A double blinded is conducted to reduce or eliminate bias between the participants and researchers.
Therefore, the statement that explains why randomized controlled trials are often "double blind" is as follows: to decrease bias by ensuring both the participants and researchers do not know who is receiving the treatment and who is not.
