Explain what is most likely to be different about the poorly drained portion of the pasture in the following scenario. Situation: A farmer has noticed that, while the majority of a pasture drains well without drying out and supports lush grass and leafy herbs, one portion is often poorly drained. The soil there is hard and compacted, and it is regularly invaded by a range of wild plants, including Russian Sage, asters, yarrow, and purple coneflowers. The farmer takes soil samples to discover what is different about this portion of his pasture.

This is ur answer…

Hope it helps u mate…

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
