- Why are animals used in biological research? What considerations are maintained by scientists?How can we preserve animal reproduction?Which of the following is/are exaptations? a) Group of answer choices b) Feathers of birds c) Production of many small offspring in high predation sites. d) mammalian inner ear ossicles (bones) e) Development of a waxy cuticle in dry environments.
- Which of the following is not a feature common to most animals? a. development into a fixed body plan b. asexual reproduction c. specialized tissues d. heterotrophic nutrient sourcingIn 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?Your colleague is studying a newly discovered organism. She is becoming increasingly convinced that the organism is an arthropod. You find that you must respectfully disagree when you note that the organism has a set of distinctly non-arthropod characteristics. The features that cause you to exclude the organism from the arthropod grouping are antennae, six legs, and mandibles. pseudocoel, closed circulatory system, and ventral heart. Malpighian tubules, ommatidia, and tagmata. jointed legs, ecdysis, and an exoskeleton. compound eyes, book lungs, and a hemocoel.
- Humans as individuals have a number of disadvantages compared to other animals. For instance we are not very fast, strong, cannot see well in the dark, have a poor sense of smell and hearing compared to other animals, and we are not very good climbers. With all of these disadvantages how is it that we have been so successful? Shouldn't we have gone extinct as other humanoids such as Homo erectus? Discuss why humans have beaten the odds and are so successful.Spirochaetes are free-living, anaerobic bacteria that contain spiral-shaped cells. Nematodes are roundworms that are incredibly diverse and, as a group, have adapted to survive in all environments. Which of the following statements accurately describes the DNA of both groups? * The spirochaete genome is smaller than the nematode genome. Nematode DNA is circular. Spirochaete chromosomes are composed of just DNA while nematode chromosomes also include specialized proteins. O Spirochaete DNA is linear.how would you describe human beings to aliens?
- What is segmentation? A. a subdivided body plan with repeated parts B. a body plan where each segment contains a different organ system C. a form of reproducing where the organism creates new segments that break off D. a body with a head and many segments that carry only reproductive organs right © 2003-2022 International Academy of Science.

This tree should be primarily based on physical characteristics, such as: I. Presence or absence of a backbone II. Ability to breathe in air or water III. Cold or warm blooded IV. Carnivore, herbivore, or omnivore V. Presence or absence of hair/fur VI. Any other external structure such as horns TO DO: Lay all the animals on their desks and separate them into two groups using the physical characteristics above☝ The animals are on the picture.In the evolutionary tree of vertebrates, birds are most closely related to: a) Mammals b) Crocodiles c) Placoderms d) Salamanders
