The molecule coded directly from dna is represented by number:

Hello. You forgot to add the diagram required to answer that question. The diagram is attached below:

1

Explanation:

The molecule represented by the number 1, is an RNA molecule and we can see that, because the RNA molecule has only one strand and has the uracil nitrogen base (u), as we can see in the diagram.

RNA is the molecule encoded directly from DNA, since it is manufactured using one of the DNA strands as a model, through a process called transcription that is performed by RNA polymerase.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
