The test: to understand if the actn3 protein affects running ability, researchers conducted a test. they recruited a group of competitive runners and measured the level of actn3 protein molecules each runner had in their bodies. then, they had the runners participate in a sprint (a short-distance run). during the test, the runners sprinted as fast as they could for 100 meters. evidence: scientists found that the runners who sprinted the fastest had the highest amount of actn3 protein molecules in their bodies. do you think that this evidence shows that the actn3 protein determines running ability? explain your ideas using the words protein, trait, and feature in your response. ​

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

answer: that would be cheating

explanation:

cell division is not regulated in tumor cells.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
