Step by step
Solved in 2 steps
- The generation time of a tree species is likely to be 50 to 100 times longer than that of many species of herbivorous insects and parasitic fungi,so a tree’s potential rate of evolution should be slower. Why have trees, or other organisms with long generation times, not become extinct as a result of the potentially more rapid evolution of their natural enemies?What does the following phrase mean? “Evolution is a discipline of reconstructing past relationships, not filling in a linear chain of ‘missing links.’” Use vocabulary from the textbook to help you answer this question. I am looking for at least two SOLID paragraphs, since this question is worth two points.What is Abiogenesis? Make a comprehensive essay about the theories on the Origin of Life: Abiogenesis.
- Of the trees in the diagram below, which one of the four trees depicts a different evolutionary history than the others? A. Tree a. B. Tree b. C. Tree c. D. Tree d.Lesson: Perpetuation of Life Give at least five examples of genetic engineered plants/animals. a. b. c. d. e. Give at least 2 examples of the following: Fission- - Budding- - Fragmentation- - 3. Give at least 4 examples of plants which can do Vegetative Reproduction. a. b. c. d.The second name sets a particular species apart from the rest of the species within the genus? True or False The evolution of plant life can be based on mutation? True or false
- For about how many years of geological time have the dinosours existed on earth?? Did dinosours exist at the same time as humans? How do scientists determine when an era begins and when it ends? What is the purpose of making a geological timelineWhich of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..- How much time does it take for 1 half-life to occur? -Approximately how many half-lives are there in 20,000 years? -If 30 percent of the carbon-14 atoms remain in a sample, how long ago did the organism die?
- Volcanic ash can be used to date fossil finds because each time it is expelled by an eruption it has the same relative proportions of radioactive isotopes. True or FalseWhen a radio-isotope in a fossil with a half-life of 4,000 years has been reduced to 25% of its original amount, how old is the fossil?Why is it so important to learn about the Piltdown Hoax? Do you think it demonstrates that scientists may lose their objectivity when they want data to fulfill their expectations and desires or does it demonstrate the self-corrective nature of science? Why were people so willing to believethat one of the oldest specimens was found in south England?
