1. A student wants to buy a new skateboard. He wants to find out if the size of the wheels affects how far he can coast on the skateboard. He also wants to find out if the type of material the board is made of
affects how far he can coast on the skateboard. He decides to compare two skateboard models that are
the same size but are made of different materials and have different size wheels:
Model 1
Model 2
Plastic skateboard
Large wheels
Wooden skateboard
Small wheels
He pushes off as hard as he can and stands on the skateboard until the skateboard comes to a stop. He
tries each skateboard 5 times to see how far he can go. He uses the same pavement and the same
starting point for all the trials. He finds out that he can coast farther with Model 1. What can he conclude
from this test?

It is evolution, because we all have some of the same traits like eye color or shape or ears.

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
