Which is part of the theory of evolution by natural selection?
Katen [24]

Answer:

The correct answer is: A. Only the best-adapted animals in a population survive.

Explanation:

  • Natural Selection is the process by which the individuals of a species which has the potential to sustain and survive in adverse or changing environment gets a survival advantage over those individuals which are unable to adapt themselves to altered environmental conditions.
  • As the less potent individuals die in altered environmental conditions the  adaptable individuals escapes competition with them for natural resources.
  • Evolution causes species to alter their characteristics depending upon the demand of the conditions. These changes can vary, can be less or drastic.
  • Animals pass all the newly adapted traits to the successive generations either as genetic traits or as acquired traits, as this is necessary for the offspring to survive in the altered environment.
  • Natural selection is best defined as "the survival of the fittest".

b) Glycolysis is the process by which glucose is converted to two molecules of pyruvate.

Glycolysis is a process in which a glucose molecule is broken down into two molecules of pyruvate. The process of glycolysis occurs without oxygen therefore it can occur in both aerobes and anaerobes.

The process of glycolysis occurs in the cytoplasm of the cell and the products of glycolysis are 2 molecules of pyruvate, 2ATP, and 2 NADH molecule. Then the pyruvate molecule gets into mitochondria which it's complete oxidation takes place. Therefore the right answer is a and b.
