- Your friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks” Which statement is the best response to correct your friend’s misconception? Group of answer choices Overproduction of offspring leads to a struggle for survival. Disuse of an organ may lead to its eventual disappearance. Characteristics acquired during an organism's life are generally not passed on through genes to its offspring. Only favorable adaptations have survival value.What are weaknesses of life histories?Why must a plant or animal make trade-offs among growth, reproduction, defenses, and other adaptive traits?
- All of the following are common or recurrent themes in biology except A) Organisms grow, develop, and reproduce B) Function determines structure C) Matter is recycled while energy flows through living systems D) Living organisms maintain homeostasis E) Evolutionary processes explain both the unity and adaptive diversity of life.What is an evolutionary tree? Is there a precise evolutionary tree known by science that explains the emergence and origin of every type of living being?In what ways does evolution depend on transfer of information? In what ways does transfer of information depend on evolution?
- Which of the following is correct concerning adaptations? (Choose one.) Group of answer choices a)They always increase an organism's ability to survive better than other individuals in the population. b)They can increase an organism's ability to survive better or reproduce better than other individuals, but not both at the same time. c)They increase an organism's ability to reproduce better than other individuals in the population, in a given environment. d)They result from any mechanism of evolution.What is biological constraints ?Why is variation amongst individuals of the same species important in ensuring species survival?
