Answers
Answer:
Explanation:
A) The offspring cells or organisms acquire the genetic information of their parents through a mechanism known as inheritance. The inherited traits undergo modification. Through hereditary, variations between individuals can accumulate and cause species to undergo evolution by natural selection.
B) Complex proteins are made up of various protein molecules which are linked by non-covalent bonds. Amino acids are the basic units of the proteins. They link together to form a primary structure, polypeptide chain. Secondary structure is made up of beta sheets or alpha helices.
C)The theory of evolution has been supported by proof from a wide variety of scientific discipline, including paleontology, geology, genetics and developmental biology. The first proof is the common traits, you and your closest relatives look more alike than you and your cousins.
D)Anatomical evidences help us to study how species have evolved over a period of time. Analogous structures support the theory of evolution and explain the fact that how species build up adaptations in order to fit in an environment whereas homologous structures help us to understand common ancestry.
E) Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
