Provides an overview of plant life history and plant phylogenetics. Describes the differences between and characteristics of charophytes, bryophytes, seedless vascular plants, seeded vascular plants, and angiosperms. Provides a phylogeny with dominant generations, spore characteristics, and other traits. Compares and contrasts the characteristics of all plants (including charophytes) and land plants, mentions relevant analogous traits.

BIO206 Final Exam; Questions and Answers 100% Correct Homoplasy Correct answer-A similar (analogous) structure or molecular sequence that has evolved independently in two species. Problems with Homoplasy Correct answer-It can create an unpredictable gain or loss of a specific trait over time and during the evolution of new species Slowly evolving genes Correct answer-Useful for distantly related species Rapidly evolving species Correct answer-useful for closely related species Most us...

Life History -Correct Answer Pattern of how organisms allocate time and energy among the various activities throughout its life that affect survival, maturation, and reproduction Life History Traits -Correct Answer Longevity, growth rate, age at sexual maturation, age at first reproduction, number of reproductive bouts per lifetime, number of offspring per reproductive bout Ecdysis -Correct Answer periodic shedding of the cuticle in arthropods or the outer skin in reptiles (cicadas in lect...

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The formation of new species in populations that are geographically isolated from one another. allopolyploidy - a species with multiple sets of chromosomes derived from different species Alpha (origination...

PNB 2250 Exam 1 Study Set Questions and Answers 100% Pass Animals Traits - -distinguish them from plants and single cell organisms -eukaryotic, multicellular, complex tissues, differentiated tissues -heterotrophic: consume living or dead plants or animals -movement or sessile (stuck to something) Advantages of Multicellularity - 1. Cells dedicated to specific tasks, increase in efficiency 2. Not all genes expressed, saves energy 3. Cells farther away from surface (easier to maintain hom...

Bio 250 - Unit 2 Exam Questions and Answers 100% Passs 4 Postulates of Natural Selection: - 1) Variation exists between populations (individuals have different phenotypes) 2) Variation is heritable (it's a genetic component) 3) In each generation, there is differential survival 4) Survival and reproduction is not random Pre-adaptations/Exaptations: - Trait/feature that takes on a function when none previously existed or that differs from its original function (ex. Panda wrist bone evo...

IB Biology: Evolution Questions and Answers Already Passed What is a theory? A comprehensive explanation of some aspect of nature (vs a hypothesis, which is just a prediction as to the result of an experiment). What were some ideas from Darwin's time that influenced his work? French naturalist Buffon in the mid-1700s studied fossils and said the Earth must be older than previously assumed; Lamarck in the early 1800s proposed that life changes over time. Define acquired vs heritab...

Natural Selection - Answer A theory in which individuals with certain traits produce more offspring than others without these traits. Evolution - Answer The gradual change in a species over time. Adaptation - Answer When the heritable trait increases an individuals fitness in a particular environment. Ancestral trait - Answer Is a character that existed in an ancestor. Derived trait - Answer Is one that is a modified form of the ancestral trait, found in a descendants....

control system components of homeostasis - (1) sensor (protein based) (2) controller (3) effector (changes physiological variable) physical factors of animals - (1) energy input (cost/benefit ratio) (2) waste removal (3) growth and development (4) impacts of physics, chemistry, geometry on body form convergent evolution - organisms independently evolve similar traits as a result of having to adapt to similar environments limited solutions to the same problem analogous structures - flig...

Biology 100 ASU - Life Finds a Way Questions and Answers Graded A+ What characterizes natural selection? A) Development of traits enhancing fitness B) Differential survival and reproduction C) Survival based on strength D) Selection for optimal phenotype B) Differential survival and reproduction The prehensile tail has evolved independently in various lineages like chameleons, kinkajous, and New World monkeys, enabling them to thrive in forest canopies. This adaptation exemplifies: ...

AP Biology Exam Questions and Answers Graded A+ What are the 2 theories of evolution? Explain each Gradualism- geologic changes result from slow, gradual, continuous process Punctuated Equilibrium- Long period of stasis punctuated by short bursts of significant change. What was Lamarck's theory and why was it wrong? Lamarck = Inheritance of Acquired characteristics- traits acquired during lifetime could be passed on What is natural selection Comptetition for limited resources re...
