Answer the following question given this paragraph: Dialysis Technician Dialysis is a medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration. When kidney function fails, dialysis must be done to artificially rid the body of wastes and fluids. This is a vital process to keep patients alive. In some cases, the patients undergo artificial dialysis until they are eligible for a kidney transplant. In others who are not candidates for kidney transplants, dialysis is a lifelong necessity. Dialysis technicians typically work in hospitals and clinics. While some roles in this field include equipment development and maintenance, most dialysis technicians work in direct patient care. Their on-the-job duties, which typically occur under the direct supervision of a registered nurse, focus on providing dialysis treatments. This can include reviewing patient history and current condition, assessing and responding to patient needs before and during treatment, and monitoring the dialysis process. Treatment may include taking and reporting a patient's vital signs, preparing solutions and equipment to ensure accurate and sterile procedures. Q: Dialysis is a medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration. when kidney function fails, dialysis must be done to artificially rid the body of this? Choices: - bile juices - mucus and phloem - calories - waste and fluids A:
waste and fluids
Answer the following question given this paragraph: Aquatic biomes in the ocean are called marine biomes. Organisms that live in marine biomes must be adapted to the salt in the water. For example, many have organs for excreting excess salt. Marine biomes include the oceans, coral reefs, and estuaries ( Figure below ). The oceans are the largest of all the ecosystems. They can be divided into four separate zones based on the amount of sunlight. Ocean zones are also divided based on their depth and their distance from land. Each zone has a great diversity of species. Within a coral reef , the dominant organisms are corals. Corals consist partially of algae, which provide nutrients via photosynthesis. Corals also extend tentacles to obtain plankton from the water. Coral reefs include several species of microorganisms, invertebrates, fishes, sea urchins, octopuses, and sea stars. Estuaries are areas where freshwater streams or rivers merge with the ocean. Q: Aquatic biomes in the ocean are called what? Choices: - jungle biomes - arid biomes - artificial biomes - marine biomes A:
marine biomes

Answer the following question given this paragraph: The student athlete in Figure below is practically flying down the track! Running takes a lot of energy. But you don't have to run a race to use energy. All living things need energy all the time just to stay alive. The energy is produced in chemical reactions. A chemical reaction is a process in which some substances, called reactants, change chemically into different substances, called products. Reactants and products may be elements or compounds. Q: What is a process where some substances called reactants change chemically into different substances called products? Choices: - crystals reaction - carbon reaction - non-chemical reaction - chemical reaction A:
(Answer)
chemical reaction
