Solved by a verified expert:This is a biology exam review. Needs for it to be thorough and descriptive. Module 8. Cell communication and hormone systems serve to maintain homeostatic environments and coordinate physiology. To test whether you know this material, challenge yourself to: (a) Use a physiological example to explain the concept of homeostasis and to describe the phenomenon of negative feedback in terms of a detection system, set-point, and effectors. Tell why positive feedback cannot contribute to homeostasis. (b) Compare and contrast lipid and protein hormones and the ways they are sent and received.(c) Explain the function of an endocrine gland. Tell how animal cells detect and coordinate responses to endocrine signals, either in the form of peptide hormones or steroid hormones.(d) Compare and contrast the way in which nerve and hormone signals are sent to distant parts of the body to enable control and coordination of animal systems and response.(e) Diagram the glucose homeostasis control via the pancreas.Module 7. Species have diverse life cycles and modes of reproduction that maximize reproductive success and reflect evolutionary tradeoffs.To test whether you know this material, challenge yourself to:A. Describe the role of sexual and asexual reproductive phases in the life cycles of fungi, plants, and animals. Identify examples in which sex and reproduction are decoupled and examples where the two are closely connected. Explain how bacterial populations maintain genetic variability.i. Review from the general sexual life cycles for animals, plants, and fungi, remembering the terms meiosis, fertilization, haploid, diploid, sporophyte, gametophyte, dikaryon, karyogamy, plasmogamy, and “alternation of generations”.ii. Review from the difference between asexual reproduction and sexual reproduction, and state the evolutionary advantages and potential limitations of each in different environments. B. Give examples of reproductive adaptations of plants, animals, and fungi to terrestrial life.C. Relate the parts of a flower to the production and dispersal of pollen, seeds, and fruits, and discuss how interactions among species are important for plant reproductive success. Explain the innovations and coevolution between angiosperms and animals have contributed to the overwhelming success of the angiosperms. D. Give examples of how plants use hormones to control the timing of seed dormancy, germination, and fruit ripening, and explain the evolutionary benefit of each. IDEA 2. Development of multicellular bodiesA. In specific terms, describe how cell position and cell communication can lead to differential gene expression, and thus to production of specialized tissues i. Describe the role of master regulatory genes, such as Hox genes in animals and MADS BOX genes in plants.B. Compare and contrast development patterns in plants and animals, including the terms meristem, developmental plasticity, gastrulation, germ layers, and indeterminate growth.i. Describe the basic plant organs and tissues, and give examples of how the three main plant organs are adapted to specific environments and functions. Explain how structure and function are related using a plant tissue and its cells as an example.
