Answer:
These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine. The advantage of this mechanism is that the long-term maintenance of body fluids isn't as dependent on external water sources as once believed.
Tubular reabsorption is the process that moves back into the bloodstream the solutes and water out of filtrate. It is so called because this is the second time they have been absorbed in which the first time was when they were absorbed and transported from the digestive tract into the bloodstream. The substances travels from the filtrate of the proximal convoluted tubule and next to the LOOP OF HENLE.
Answer;
-PET scan
A PET scan uses radioactive markers in the blood to monitor blood flow and metabolic activity via x-ray
Explanation;
-A positron emission tomography (PET) scan is an imaging test that helps reveal how the tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.
-A PET scan is used to diagnose certain health conditions, to plan treatment, to find out how an existing condition is developing, and to see how effective a treatment is.
-In a PET scan, a machine detects radiation that is emitted by a radiotracer. A radiotracer consists of radioactive material that is tagged to a natural chemical, such as glucose.
Nonrenewable resources and found it fixed amount hence not managing properly will lead to full use of it and cannot be replaced
Explanation:
- Nonrenewable resources are found in the ground and they are the natural resources created by nature
- It includes fossil fuels, like natural gases, oil, coal, etc and also the minerals used for making metals
- These natural resources have taken more than human's life span to form, up to million years. Hence, replacing of these natural resources are not possible
- Renewable natural resources are trees, water, air. These resources can be recycled and they are also circulating in the atmosphere in the form of a cycle.
- Hence, nonrenewable resources should be managed properly for it last for the coming generations.
