In any population there will be variations of certain characteristics. for example, in the giraffe population there is a variation in neck lengths among individuals. some have longer necks and some have shorter necks. which of these events would the giraffes with the longer necks have the best chance of surviving?
a) loggers come in a chop down all of the trees
b) insects can only eat the highest leaves due to the canopy
c) a plant disease infects the trees, resulting in total leaf death.
d) monkeys swarm in and tear off all of the lower leaves to use for shelters

Hi there!

The best possible scenario for the giraffes with longer necks to survive would be one in which all the lower leaves somehow disappear! This would mean only giraffes with longer necks can eat therefore those will have a better chance of surviving. Luckily the answer that fits that perfectly would be...

D. Monkeys swarm in and tear off all of the lower leaves to use for shelters.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
