For temperature, the reaction will slow down and eventually stop. Above 40 degrees the enzyme will denature. For the pH, amino acids' component atoms and molecules will begin to ionise. Due to this the enzyme will then change shape.
<u>Evolution is sometimes a controversial:</u>
Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.
I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.
I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.
Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
