Many farmers and gardeners compost their plant and animal waste. the living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. the next season, farmers use this substance as a natural fertilizer for their crops. a biology student has grown tomato plants for several years. until now, he used an artificial fertilizer formulated for tomato plants. this fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. the student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. answer the following questions to plan an investigation using the steps of the scientific method and the student find the answer to his question. part f how does the design of your experiment control for outside factors that may affect the results

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

wha is what i will use to get my free points

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
