In a positive feedback system, the response enhances or intensifies the original stimulus. This means that when the original stimulus is detected, the response is triggered and it amplifies the stimulus, leading to a greater response. This creates a loop where the response further stimulates the stimulus, resulting in a continuous increase in the response. Therefore, the statement "True" is correct.

A tissue is a group of similar cells and their surrounding materials performing specific functions. Tissues are the building blocks of organs and are specialized to carry out specific functions in the body. They can be classified into four main types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each type of tissue has its own unique structure and function, allowing them to work together to maintain the overall function and health of the organism.

A person lying face down would be in the prone position, not the supine position. The supine position refers to lying face up, while the prone position refers to lying face down. Therefore, the given statement is false.

The highest level of structural organization is the organism level. This level includes all the organ systems working together to maintain the overall function and health of the organism.

A plane that separates the body into unequal right and left sides is called a parasagittal plane. This plane is parallel to the midsagittal plane, which divides the body into equal right and left sides. The parasagittal plane allows for the examination of specific structures on one side of the body without affecting the other side. It is often used in medical imaging and surgical procedures to focus on particular areas of interest while minimizing disruption to the rest of the body.

The sweat glands producing the sweat would be considered the effectors in a feedback loop. Effectors are the part of the loop that respond to the stimulus and produce a response to bring the controlled condition back to its set point. In this case, the controlled condition is the body temperature, and the stimulus is the increase in body temperature due to the workout. The sweat glands, as effectors, respond to this stimulus by producing sweat to cool down the body and bring the temperature back to the set point.

Metabolism refers to all of the body's chemical processes, including both anabolism and catabolism. Anabolism is the phase of metabolism that builds up new substances, such as the synthesis of proteins and the storage of energy in molecules like glycogen. Catabolism, on the other hand, is the phase of metabolism that breaks down substances, such as the breakdown of carbohydrates, fats, and proteins to release energy. Therefore, the correct answer is metabolism, anabolism, catabolism.

The growth on the urinary bladder is located in the hypogastric region. The hypogastric region is the lower central region of the abdomen, which is where the bladder is situated. This is the most appropriate region to position the camera for an x-ray of the bladder growth.

The peritoneum is a membrane that lines the abdominal cavity, not the thoracic cavity. The thoracic cavity is associated with the pericardium, mediastinum, and pleura.

During fetal development, unspecialized stem cells have the ability to differentiate into specialized cells, including brain cells. This process of differentiation allows the stem cells to acquire specific structures and functions necessary for their role in the brain. Therefore, the correct answer is differentiation.

The fluid located within cells is called intracellular fluid, while the fluid located outside of the cells is called extracellular fluid.
