Unit 8 Chemical Evolution, Prokaryotes, Eukaryote Evolution, Protista 36. Discuss the evolutionary significance of death. Their data are shown below: Student A Student B Student C a b Plant Seedling Mass grams Day 30 Day 1 4 24 5 35 4 64 Identify three different environmental variables that could account for differences in the mass of the seedlings at day 30. These minor factors are always worth points. After four generations, the following results were obtained. It really bothers me when students miss points because they glossed over the details. Discuss the theories that have been proposed to explain how these substances are transported.
This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. Show all your work and explain the importance of your final answer. Proteins—large complex molecules—are major building blocks of all living organisms. Explain how the reduction and rearrangement are accomplished in meiosis. It is advisable to research on topics that you are good at because it will be easier for you to defend your arguments. One of the genres of essays that students fear to write is an argumentative text.
The day was bright and sunny, and the wind was calm. Trichomes are hairlike outgrowths of the epidermis of plants that are thought to provide protection. Describe the production and processing of a protein that will be exported from a eukaryotic cell. Discuss the process of cell division in animals. Scientists recently have proposed a reorganization of the phylogenetic system of classification to include the domain, a new taxonomic category higher more inclusive than the Kingdom category, as shown in the following diagram. Describe the structure of a generalized eukaryotic plant cell.
It really bothers me when students miss points because they glossed over the details. Include in your answer one way in which human activity has an impact on the nutrient cycle you have chosen. However, when they ask for help from us, we make it easier for them. It shows the grader that you are not intelligent enough to assess the question accurately and select the correct answer from your store of knowledge. Describe the processes of speciation.
Be sure to clearly state the principles addressed in your discussion. Many physioligical changes occur during exercise. Discuss the adaptations that have enabled flowering plants to overcome the following problems associated with life on land. Each author presents a host of ideas for activities, resources, and assessments. The unique properties characteristics of water make life possible on Earth. Angiosperms flowering plants and vertebrates obtain nutrients from their environment in different ways.
Discuss how electrons are generated in photosynthesis and why the three samples gave different transmittance results. The distance travelled will also affect diffusion rates. What is the initial rate of this enzymatic reaction? Numerous environmental variables influence plant growth. For example, if a question asks you to describe mutualism, the grader is going to look for a definition of mutualism to award a point, and then an elaboration of mutualism, like an example, to give an additional point. College students need to learn how to write biology essay perfectly to match their level of learning. If the temperature is colder, the rate of diffusion is much slower as a result of all particles becoming closer together. Unit 10 Vertebrates, Basic Animal Structure and Function 39.
Unit 7 Evolution, Population Genetics, Speciation 29. Communication occurs among the cells in a multicellular organism. Describe the structure of a bean seed and discuss its germination to the seedling stage. Pheromones Mimicry Stereotyped behavior instinct 25. Describe the effects of plant hormones on plant growth and development. Discuss how various types of organisms and their biochemical reactions contribute to the recycling of either carbon or nitrogen in an ecosystem. A genetics question may follow a taxonomy question, which may follow a question about the Krebs cycle.
The above information is all you need in creating meaningful information for your biology extended essay. The topics may cover various biology issues. Having written this essay I feel that J. Indicate when and how each of the following occurs in meiosis. Explain the mechanisms involved in conducting water through these tissues. Structure and function are related in the various organ systems of animals.
