AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Lichens**: Lichens are a symbiotic relationship between two organisms: an alga and a fungus. In this relationship, both partners benefit from each other. 2. **Role of Alga**: The alga is responsible for photosynthesis, which means it can produce food using sunlight, carbon dioxide, and water. This food is then shared with the fungal partner. 3. **Role of Fungus**: The fungus provides structure and protection to the alga and helps in the absorption of water and nutrients from the environment, which is essential for both organisms. 4. **Separation of Partners**: If the algal and fungal partners are separated, the alga will continue to survive on its own because it can produce its own food through photosynthesis. 5. **Impact on Fungus**: The fungal partner, however, relies on the alga for food. Without the alga, the fungus cannot perform photosynthesis and will eventually die due to lack of nutrition. 6. **Conclusion**: Therefore, if the algal and fungal partners are separated, the alga will survive, but the fungal component will die. **Final Answer**: The algal partner will survive while the fungal partner will die. ---

  • Which of the following statements regarding species interdependence are true? 1. An association of two species where one is benefited and other remains unaffected is called mutualism. 2. An interspecific association where both partners derive from each other is called commensalism. 3.

  • Among Nature's most intriguing phenomena are the partnerships formed by any different species. The name used for these relationships, Symbiosis, comes from Greek meaning "living together". Not all symbiotic relationships are the same. There are some called commensal relationships, in which one partner gains a benefit while the other gains little or none but is not harmed. One example is the relationship between two types of fish - remoras and sharks. The remora, which is long and often striped, attaches itself to a shark (sometimes to another type of fish or a whale), using a sucker on its head. When the shark makes a kill, the hitchhiker briefly detaches itself to feed on the scraps. Another type of symbiotic relationship is parasitism, in which one partner benefits at the expense of others. Ticks and tapeworms are among familiar parasites. The third type of symbiotic relationship, called mutual ism, is a true partnership in which both partners benefit. The relationship may be limited as when zebras and wildbeast graze together on the vast African grasslands. Each species can survive on its own, but together their chances of detecting predators are improved because each contributes a specially keen sense. (Zebras have the better eyesight, wildbeast, hearing and sense of smell). In a few cases partners are so interdependent that one cannot survive without the other. Most mutualistic relationships probably lie somewhere in between The passage talks about how animals

    A
    help each other.
    B
    live together.
    C
    take advantage of the weaker ones.
    D
    are related to each other.

    Passages are given with 5 questions following each of them. Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it. The development of a mine consists of several principal activities. conducting a feasibility study, including a financial analysis to decide whether to abandon or develop the property, designing the mine, acquiring mining rights, filing an Environmental Impact Statement (EIS), and preparing the site for production. Preparation could cause environmental damage by excavation of the deposit to remove overburden (surface material above the ore deposit that is devoid of ore minerals) prior to mining. Extraction is the removal of ore from the ground on a large scale by one or more of three principal methods, surface mining, underground mining, and in situ mining (extraction of ore from a deposit using chemical solutions). After the ore is removed from the ground, it is crushed so that the valuable mineral in the ore can be separated from the waste material and concentrated by flotatin (a process that separates finely ground iminerals from one another by causing some to float in a froth and other to sink), gravity, magnetism, or other methods, usually at the mine site, to prepare it for further stages of processing. The production of large amounts of waste material (often very acidic) and particulate emission have led to major environmental and health concerns with ore extraction and concentration Which of the following is/are the principal requisite(s) for development of a mine?

    Read the passages carefully and select the best answer to each question out of the given four alternatives. Culture is defined as a people.s way of life. It entails how they dress, how they speak, the type of food they eat, the manner in which they worship, and their art among many other things. Indian culture, therefore, is the Indians. way of life. Because of the population diversity, there is immense variety in Indian culture. The Indian culture is a blend of various cultures belonging to diverse religions, castes, regions follow their own tradition and culture. Indian Culture is one of the oldest cultures in the world. India had an urban civilization even during the Bronze Age. The Indus Valley Civilization (Harappan Civilization) dates back to 3300 BC-1300 BC. Distinct cultures different from each other co-exist together in a single country. Thus, in India, there is unity amidst vast cultural diversity. The way people live in India is reflected in its culture. India is a land of unity in diversity where people of different sects, caste and religion live together. India is also called the land of unity in diversity as different groups of people co-operate with each other to live in a single society. Unity in diversity has also become the strength of India. According to the passage, which of the following is TRUE about unity in diversity?
