Adaptation refers to the ability to adjust and change according to one's environment or circumstances. In the context of living with nature, it implies being able to acclimate and thrive in natural surroundings, such as adapting to the weather, terrain, and resources available. This could involve developing survival skills, altering behaviors or habits, and finding ways to coexist harmoniously with the natural world. Therefore, adaptation is the most suitable term to describe the ability to adjust to living with nature.

Charles Darwin is the correct answer because he is widely recognized as the inventor of the theory of evolution. Darwin's theory, known as natural selection, revolutionized the field of biology and our understanding of how species evolve over time. His groundbreaking work, "On the Origin of Species," published in 1859, presented evidence for the concept of common descent and the idea that species adapt to their environment through natural selection. Darwin's theory remains a cornerstone of modern biology and has had a profound impact on our understanding of the natural world.

Incubating chicken eggs for 21 days is a true statement. This is because the average incubation period for chicken eggs is approximately 21 days. During this time, the eggs are kept in a controlled environment with the right temperature and humidity levels to allow the embryos to develop and eventually hatch into chicks.

Worms breathe through their skin. Unlike humans and many other animals, worms do not have lungs or gills. Instead, they have a moist and permeable skin that allows oxygen to pass through and carbon dioxide to be released. This process is known as cutaneous respiration. The skin of worms needs to remain moist in order for them to efficiently exchange gases with their environment.

Fungi is the correct answer because unlike plants, fungi do not have chlorophyll. Chlorophyll is a pigment that enables plants to carry out photosynthesis, which is the process of converting sunlight into energy. Fungi, on the other hand, obtain their nutrients by decomposing organic matter or by forming symbiotic relationships with other organisms. Therefore, they do not require chlorophyll for energy production.

Islam does not agree with the theory of evolution. The Islamic belief is that Allah created human beings and other creatures in their present form, rather than evolving from a common ancestor over time. This belief is based on the interpretation of the Quran, which states that Allah created Adam and Eve as the first humans. Therefore, the correct answer is false.

Fish that live in saltwater environments have a more concentrated urine than fish that live in freshwater environments because saltwater fish constantly lose water through osmosis, while freshwater fish gain water through osmosis. To maintain the balance of water and solutes in their bodies, saltwater fish need to excrete a more concentrated urine to conserve water and eliminate excess salts. This adaptation helps them survive in their specific environment.

The correct answer is cow and buffalo because both of these animals are ruminants. Ruminants are a group of mammals that have a specialized digestive system capable of breaking down plant materials through a process called rumination. They have a four-chambered stomach that allows them to ferment and digest cellulose-rich plant material. Both cows and buffaloes are examples of ruminants commonly found in agricultural settings, where they are raised for their milk, meat, and other products.

The correct answer is pig and snake because they are both examples of vertebrates. Vertebrates are animals that have a backbone or spinal column, and both pigs and snakes possess this characteristic. Stingrays, on the other hand, are not vertebrates as they belong to a group of animals called cartilaginous fish, which lack a true bony skeleton. Therefore, stingrays are not a correct answer in this context.

The plants mentioned in the answer (Venus flytrap, Cape Sundew, bladderworts) are all examples of carnivorous plants. Unlike typical plants that produce their own food through photosynthesis, these plants have adapted to obtain nutrients by trapping and digesting small insects or other organisms. This makes them heterotrophs, as they rely on external sources for their nutrition rather than producing it themselves.
