Ques: Q: What is the medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration called? Read this paragraph and choose the correct option from the provided answers: 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. 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 life-long 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 and preparing solutions and equipment to ensure accurate and sterile procedures. Choices: - tumors - digestion - arthritis - dialysis A:
Ans: dialysis

Ques: Q: Which is the dominant stage of the lifecycle of a fern? Read this paragraph and choose the correct option from the provided answers: The dominant stage of the lifecycle of a fern is the sporophyte, which consists of large compound leaves called fronds. Fronds fulfill a double role; they are photosynthetic organs that also carry reproductive organs. The stem may be buried underground as a rhizome, from which adventitious roots grow to absorb water and nutrients from the soil; or, they may grow above ground as a trunk in tree ferns (Figure 25.20). Adventitious organs are those that grow in unusual places, such as roots growing from the side of a stem. Choices: - gametophyte - larvae - zygote - sporophyte A:
Ans: sporophyte

Ques: Q: What theory explains most of the features of earth's surface? Read this paragraph and choose the correct option from the provided answers: The theory of plate tectonics explains most of the features of Earth's surface. Plate tectonics helps us to understand where and why mountains form. Using the theory, we know where new ocean floor will be created and where it will be destroyed. We know why earthquakes and volcanic eruptions happen where they do. We even can search for mineral resources using information about past plate motions. Plate tectonics is the key that unlocks many of the mysteries of our amazing planet. Choices: - Big Bang theory - flat earth theory - string theory - plate tectonics A:
Ans: plate tectonics

Ques: Q: Are coral reefs found in warm or cold water? Read this paragraph and choose the correct option from the provided answers: Coral reefs are found only in warm water. Coal swamps are also found in tropical and subtropical environments. Wegener discovered ancient coal seams and coral reef fossils in areas that are much too cold today. Wegener thought that the continents have moved since the time of Pangaea. Choices: - cool - cold - both - warm A:
Ans:
warm
