Desertification:Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid.
Deforestation: the action of clearing a wide area of trees.
Climate change: Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth's surface is warming, and many of the warmest years on record have happened in the past 20 years.
Extinction:
the state or process of being or becoming extinct.
There is a key piece of information that we are missing.
we need the following:
Kb of water= 0.512
the change in boiling point (ΔTb) can be calculated using the following formula:
ΔTb= Kb x m
we already have Kb, but we need to determine the molality (m).
1) let's convert the grams of glucose to moles using the molar mass of it. The molecule formula of glucose is C₆H₁₂O₆.
molar mass C₆H₁₂O₆= (6 x 12.0) + (12 x 1.01) + (6 x 16.0)= 180 g/mol
2) let's determine the Kilograms of water.
info:
density of water= 1.0 g/ mL or 1 grams = 1 mL
1000 grams= 1 kilogram
3) let's plug in the values to solve for molality
finally, we can solve for change in boiling point.
ΔTb= Kb x m
ΔTb= (0.512) (0.545m)=
0.279°C
Answer:
To replicate DNA or to translate DNA to RNA, you need to unzip the double helix and create an exact replica of the code. To do this, the nitrogen bases are strictly paired, A to T or U and C to G. The ends of these molecules match each other in such a way that a hydrogen bond, a strong intermolecular force, can form only between matching bases. Special proteins travel up and down the DNA strand facilitating the copying of the genetic code into RNA so that it can be decoded to create proteins.
