Historically, the x chromosome had more genes assigned to it than its physical size would seem to warrant relative to the other chromosomes. Can you suggest another explanation as to why this was the case?

Humans contain 46 chromosome or 23 pairs of chromosomes. Among them  22 pairs are autosomes and one pair contains the sex chromosome. Humans female are XX and human males are XY.

The X chromosome determines the sex of an individual and females one X chromosome is randomly inactivated. The human X chromosome has large number of genes and contains large euchromatic regions that are highly activating gene regions. The X chromosome also contains the conserved regions that are far shorter in Y chromosome. The X chromosome is large in size and has large number of genes.

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 main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
