Name: . Unit 1 Exam Life Science: Reproduction And Human Development 1) Identify three examples of recessive traits in humans and three examples of dominate traits in humans. List answers below (3 marks) RE 9.1 - Examine the process and influences on the transfer of genetic information and the impact of that understating on society past and present. Specific to indicator d- Identify examples of dominant and recessive traits in humans and other living things. Bloom’s Taxonomy – Comprehension 2) Fill in the blank with the correct term to complete the following definitions. Fill in the blank (2 marks) The contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. Each human cell contains roughly two meters of DNA. are a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. RE 9.1 - Examine the process and influences on the transfer of genetic information and the impact of that understating on society past and present. Specific to indicator C – recognize that the nucleus of a cell contains genetic information and identify the relationship among chromosomes, genes, and DNA in transmitting genetic information. Bloom’s Taxonomy – Evaluation (a choose question) 3) Compare and contrast the peppered moth pre and post industrial revolution. Analyze what occurred and how this affected the future moth populations. Short answer (4 marks) RE 9.1 - Examine the process and influences on the transfer of genetic information and the impact of that understating on society past and present . Specifically indicator F- discuss environmental factors and personal choices that may lead to changes in cell’s genetic information Bloom’s Taxonomy – Analysis 4) Illustrate what the cell looks like during the following phases of mitosis. (8 marks) Interphase Prophase Metaphase Anaphase, telophase and cytokinesis R.E 9.2 - Observe and describe the significance of cellular reproductive processes, including mitosis and meiosis. Specifically indicator A – observe and describe cell division using microscopes, prepared slides, and/ or video. Bloom’s Taxonomy – Knowledge 5) Sketch and label a diagram of an animal cell. Include the cell wall, cytoplasm, nucleus, nucleolus, and nuclear membrane. Identify which part of the cell is responsible for cellular processing. (6 marks) R.E 9.2 - Observe and describe the significance of cellular reproductive processes, including mitosis and meiosis. Indicator C – recognize that the nucleaus of a cell determines cellular processes Bloom’s Taxonomy – Application 6) True or False section Circle the best answer for the following statement: (5 marks) An advantage of sexual reproduction in living things is genetically identical offspring. True or False R.E 9.3. Indicator B – compare advantages and disadvantages of sexual and asexual reproduction for individual plants and animals, and for populations A plant that is well adapted to a rocky mountainside with little chance for cross-pollination would benefit from asexual reproduction versus sexual reproduction. True or False R.E 9.3. Indicator B – compare advantages and disadvantages of sexual and asexual reproduction for individual plants and animals, and for populations Binary fission is a form of sexual reproduction. True or False R.E 9.3. Indicator C – describe various methods of asexual reproduction in plant species (e.g., budding, grafting, binary fission, spore production, fragmentation, and vegetative reproduction) and list specific examples. Hydra is an animal species that uses asexual methods to reproduce. True or False R.E 9.3. Indicator G – describe various methods of asexual reproduction in animal species (e.g., budding parthenogenesis) and list specific examples (e.g., hydra, aphids, and hammerhead shark). The application of asexual reproduction knowledge and techniques in the agriculture industry in Saskatchewan allows specific favorable traits to be passed down through generations. True or False R.E 9.3. Indicator E – Investigate and describe applications of asexual reproduction knowledge and techniques in the Saskatchewan agricultural and/or forestry sector. Bloom’s Taxonomy – Comprehension 7) Compare and contrast sexual and asexual reproduction. List at least three comparisons and three contrasting point. (3 marks) R.E 9.2 - Observe and describe the significance of cellular reproductive processes, including mitosis and meiosis. Indicator B – Compare advantages and disadvantages of sexual and asexual reproduction for individual plants and animals, and for populations. Bloom’s Taxonomy – Analysis 8) Arrange the following terms into their proper order in regards to the major stages of human development (Starting with the first stage being the beginning of human development). (4 marks) Embryo Fetus Zygote Birth R.E 9.4 Analyze the process of human reproduction, including the influence of reproductive and contraceptive technologies. Indicator C- describe the major stages of human development from conception to birth, including reference to signs of pregnancy, X and Y chromosomes, zygote, embryo, and fetus. Bloom’s Taxonomy – Synthesis 9) Choose a word from the word bank and match it with a definition below. Write the answer to the definition on the blank provided. (5 marks) All R.E 9.4 Analyze the process of human reproduction, including the influence of reproductive and contraceptive technologies Reproductive Technology Testosterone Vas Deferens Progesterone XX Estrogen Zygote Hormone Contraceptive - A chemical substance secreted by one tissue and travels by way of body fluids to affect another tissue in your body. Also referred to as a chemical messenger. Indicator B – compare the structure and function of the male and female human reproductive systems, including the role of hormones. - A fertilized gamete Indicator C- describe the major stages of human development from conception to birth, including reference to signs of pregnancy, X and Y chromosomes, zygote, embryo, and fetus. - Women with low body fat often do not produce enough amounts of this hormone. Primarily female sex hormones. Indicator B - compare the structure and function of the male and female human reproductive systems, including the role of hormones. urethra. - Responsible for transporting mature sperm to the Indicator B - compare the structure and function of the male and female human reproductive systems, including the role of hormones. - Examples of this include in vitro fertilization, artificial insemination, and embryo transfer. Indicator E – provide examples of scientific knowledge that has resulted in the development of reproductive technologies and contraceptive technologies. Bloom’s Taxonomy - Evaluation 10) A social and cultural issue regarding sexual reproduction is abortion. How is abortion different from contraceptives? Short answer hint: related to fertilization (3 marks) R.E 9.4 Analyze the process of human reproduction, including the influence of reproductive and contraceptive technologies. Indicator F – examine social and cultural issues related to the use of reproductive and/or contraceptive technologies in humans and defend a given position on a an issue related to the use of reproductive and/or contraceptive technologies in humans.
