Natural selection is the process by which individuals with favorable traits are more likely to survive and reproduce, passing on those traits to future generations. An example of natural selection is the peppered moth, where the darker moths were more likely to survive and reproduce during the industrial revolution due to pollution darkening their environment, leading to an increase in their population.2. The water cycle is the continuous movement of water on, above, and below the surface of the Earth. It includes processes such as evaporation, condensation, precipitation, and transpiration. The water cycle is important in ecosystems as it helps distribute water resources, regulates temperature, and provides habitats for various organisms.3. Human activities, such as deforestation, pollution, and overexploitation, have a significant impact on biodiversity. These activities can lead to habitat destruction, loss of species, and disruption of ecological balance. Conservation efforts, sustainable practices, and the protection of natural habitats are crucial in preserving biodiversity.4. A food chain represents a linear sequence of organisms, where each organism is a source of food for the next. It shows the transfer of energy andnutrients from one organism to another. A food web, on the other hand, represents the interconnecting food chains within an ecosystem, showing the complex interactions and dependencies among different organisms.5. Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells and is essential for the release of energy needed for cellular functions.四、论述题Biotechnology plays a significant role in modern agriculture. It involves the application of scientific techniques to manipulate and modify living organisms, particularly crops and livestock, to enhance their traits and yield. The potential benefits of biotechnology in agriculture include increased crop productivity, resistance to pests and diseases, improved nutritional content, and reduced reliance on chemical pesticides and fertilizers.However, biotechnology also presents potential risks and concerns. One major concern is the impact on biodiversity, as genetically modified organisms (GMOs) may interact with wild relatives, potentially leading to unintended consequences. Another concern is the potential for the development of resistance in pests and diseases, which could render biotechnological solutions ineffective over time.To address these concerns, strict regulations and testing protocols are in place to ensure the safety and efficacy of biotech products. It is essential to conduct thorough risk assessments and engage in public discourse to addressethical, environmental, and health considerations associated with biotechnology in agriculture.In conclusion, while biotechnology has the potential to revolutionize agriculture and address various challenges, careful evaluation, regulation, and monitoring are necessary to harness its benefits while mitigating potential risks.。

Explain the role of the immune system in defending the body against infections.答案：The immune system plays a crucial role in defending the body against infections by recognizing and eliminating harmful pathogens such as bacteria, viruses, and otherforeign substances. It consists of various cells, tissues, and organs that work together to protect the body. When a pathogen enters the body, the immune system responds by activating white blood cells and producing antibodies that target and neutralize the invaders. This response helps to prevent the spread of infection and promotes healing and recovery.2. Describe the process of respiration in humans.答案：Respiration in humans is a process that involves the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment. It consists of two main stages: inhalation and exhalation. During inhalation, air containing oxygen is drawn into the lungs through the nose or mouth, then travels down the trachea and into the bronchi, which branch into smaller tubes called bronchioles. The bronchioles end in tiny air sacs called alveoli, where the exchange of gases occurs. Oxygen from the air diffuses across the thin walls of the alveoli into the bloodstream, where itbinds to hemoglobin in red blood cells. At the same time, carbon dioxide, a waste product of cellular respiration, diffuses from the blood into the alveoli. During exhalation, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and forcing the carbon dioxide-rich air out of the lungs. This cycle of inhal。

Explain the concept of natural selection and how it contributes to evolution.Answer: Natural selection is the process by which organisms with traits that are better suited to their environment are more likely to survive and reproduce. Over time, this leads to an increase in the frequency of these advantageous traits within a population, which can result in the emergence of new species or the extinction of less adapted ones. This process is a key mechanism of evolution, as it leads to the adaptation of species to their environments and the diversification oflife on Earth.四、论述题（20分）Discuss the importance of biodiversity and the threats it faces.Answer: Biodiversity refers to the variety of life on Earth, including the variety within species, between species, and within ecosystems. It is crucial for several reasons: 1) It provides essential ecosystem services such as pollination, water purification, and climate regulation; 2) It serves as a source of food, medicine, and other resources for humans; 3) It contributes to the resilience of ecosystems, allowing them to adapt to changes and recover from disturbances; 4) It has intrinsic value, as each species is a unique part of the Earth's heritage.Threats to biodiversity include habitat loss due to deforestation, urbanization, and agriculture; overexploitation through overfishing, poaching, and logging; climate change, which can alter ecosystems and force species to migrate or face extinction; pollution, which can poison habitats and organisms; and the introduction of invasive species, which can outcompete native species for resources. Conservation efforts are essential to protect biodiversity and the benefits it provides to humans and the planet.。
