Question

buffers are bases that cause the ph of blood to increase. buffers prevent small amounts of acid or base from changing the ph of blood. buffers are catalysts that prevent changes to the ph of blood. hobie draws the following model of a carbon atom. which change to the model would improve its accuracy? proton neutron electron move each neutron so it is next to a proton. move the protons and neutrons to a small space in the center. move the protons and electrons to a small space in the center. move all of the particles so that they are evenly spaced.

Explanation:

1. For the buffer - related question: Buffers are solutions that resist pH changes upon addition of small amounts of acid or base. They are not bases that just increase pH, nor are they catalysts.
2. For the carbon - atom model question: In an atom, protons and neutrons are located in the nucleus (a small space in the center), while electrons orbit around the nucleus. The current model has particles scattered throughout, and moving protons and neutrons to the center would make it more accurate.

Answer:

1. Buffers prevent small amounts of acid or base from changing the pH of blood.
2. Move the protons and neutrons to a small space in the center.
