Geckos are a type of small lizard that live in tropical areas. Geckos are often eaten by birds, snakes and larger lizards so they need to blend into their surroundings. In one area, scientists had always found brown and green geckos that blended in with the grass and the leaves on the ground. Over time, though they found yellow geckos in the same population. Three students were talking about why there were yellow geckos. Ciena thought that the change came from a mutation in the population. Tibor thought the change came from the environment. Sasha though that Ciena and Tibor were both right. Who do you agree with and why do you think that?

Not going to say this is right but, I think that Tibor is correct because if the land has changed more over time then the yellow ones have adapted to the new living conditions while the green one have found ways to live in that environment.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

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
