Hope you all enjoyed a bit of a vacation. This term too I will count the homeworks as one test. Get a good start and do this 2nd homework on evolution...and use the text to assure you get all correct. It's like an open book test! Don't forget to read all the answers before you select the most correct one.
Question #1: The process of natural selection is based on the assumption that:
(A) environmental changes will cause changes in the body structure in individuals
(B) most changes from generation to generation are the result of mutations
(C) part of the population of organisms always remain stable
(D) different traits inherited by offspring have different survival value.
Question #2: Which statement is NOT included as part of our modern understanding of evolution?
(A) Sexual reproduction and mutations provide variation among offspring.
(B) Traits are transmitted by genes and chromosomes
(C) More offspring are produced than can possibly survive
(D) New organs are formed when organisms need them
Question #3:Which two factors provide the genetic basis for variation within many species?
(A) asexual reproduction and meiosis
(B) mutations and sexual reproduction
(C) competition and the synthesis pf proteins
(D) ecological succession and mitosis
Question #4 Mutations can be transmitted to the next generation if they are present in
(A) hormones
(B) gametes
(C) body cells
(D) muscle cells
Question #5: Every spring, each mature female fish of a particular species produces several million eggs. However, the total population of this species remains at around 10,000 from one year to the next. State two reasons why the fish population remains approximately the same from one generation to the next.
