answer:An experiment is a scientific procedure that involves making observations, forming hypotheses, and testing those hypotheses. The other three options (A. Hypothesis, B. Assumption, and C. Observation) are all parts of an experiment. A hypothesis is a proposed explanation for a phenomenon, an assumption is a statement that is taken to be true without proof, and an observation is a piece of information that is gathered through the senses.

answer:The cash basis of accounting is a method of recording revenues and expenses when cash is received or paid, respectively. It is not required by Generally Accepted Accounting Principles (GAAP) but is often used by small businesses and individuals. Under the cash basis of accounting, revenues are recorded when cash is received from customers, and expenses are recorded when cash is paid for the costs incurred. This method is relatively simple to use and can provide a clear picture of a company's cash flow. However, it can also lead to distortions in a company's financial statements, as revenues and expenses may not be recognized in the period in which they are earned or incurred.

answer:Living organisms are interdependent on one another in various ways. This dependence can be seen through: 1. Resource sharing: Organisms rely on the resources provided by other living things for their survival. For instance, plants (producers) use sunlight, water, and carbon dioxide to produce food through photosynthesis, which is then consumed by other organisms (consumers). 2. Predation: One organism may feed on another as part of its diet. An example is the relationship between birds and insects, where birds (predators) hunt and consume insects (prey) as a source of nutrition. 3. Mutualism: In some cases, both organisms benefit from their interaction. A classic example is the relationship between bees and flowering plants. Bees collect nectar from flowers, while inadvertently pollinating the plants, which in turn helps the plants reproduce. These examples illustrate the interconnected nature of life, where the survival of one organism is often directly tied to the well-being of another.
