The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
The substance that would not transport readily in blood is : Triglycerides ( B )
<u>Although your question lacks some data below are the missing options</u>
-
Fibrinogen
-
Triglycerides
-
Monosaccharides
-
Albumin
-
Carbohydrates
Triglycerides are not readily transported in blood but it is contained in dietary fat which is been absorbed by the body through the intestine in the form of chylomicrons ( triglyceride-rich lipoproteins ).
When the chylomicrons gets to the liver, the liver disassociates the Triglycerides from the chylomicrons that is needed by the body for energy.
Hence we conclude that the substance that would not transport readily in blood is Triglycerides.

Answer:
C is surely the answer
C. Disrupting intermediate filaments will result in cells that are more susceptible to mechanical forces. In the case of the keratinocytes, disrupting keratin, a key IF in these cells, would result in very fragile cells. Less force would need to be applied using the magnetic beads to damage them or change their shape.
Answer:
The answer is A (2.5)
