Four of the different types of finches that inhabit the Galapagos Islands are pictured above. Which of the following best explains the differences in traits between the finches? A. The finches originated from different types of birds that each arrived at the islands at different times.
B. Some finches stretched their beaks out to crack hard seed, and the trait was passed on to their offspring.
C. The finches are exposed to different temperatures throughout the year causing variation depending on the season.
D. The process of natural selection caused differences to arise due to differences in available food.

spiders belong to a group of arachnids.

these traits distinguish them from insects.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
