Which of followings are true? a. Most people accept that the characteristics within a population--say pesticide resistance in lice--can change over time.
b. Some refer to the theory of evolution as "just a theory" with other competing and equally likely alternatives.
c. Some people want "special creation"--the idea that living things were created by a supernatural agent--to be considered as an alternative hypothesis alongside the theory of evolution in science education.
d. Science has rejected a hypothesis that different groups of organisms can show relationships without sharing one common ancestor.
e. Fossils are the direct evidence we have to test the theory of evolution.
f. The theory of evolution is accepted by scientists as the correct explanation for the origin of humans.

A) True

John Marshall Clark a pesticide toxicologist recently discovered in one his studies at the University of Massachusetts that about 67% to 75% of lice are no longer affected adversly by insecticides.

B) True

An alternative to the theory of evolution is the Theistic Evolution.

C) True

Creationism or Special Creation is one of the ideas of evolutions which tries to offer a better explanation to the origin of the universe.

D) False

An example would be the winds of Bees, Bats and Birds. They all use wings (with similar structure) to fly however, their origins as explained by evolution are quite different taking into conginsance how they are formed at the embryo stage.

E) True

To understand evolution, we have to study and obtain as much as possible, all the information that a fossil can provide. Many times, these information provide substantial elements which support the theory.

F) False

Evolution is a theory which scientists have accepted as ONE of the several explanations of the origins of the human species. There are other competing theories.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
