When a radioactive material is required to be placed in the body, the applications are brachytherapy and radioisotope imaging.
Radioactive materials are elements which has the ability to disintegrate by emitting radioactive substance or radiation. A good example of this is Cobalt-60, Titanium-99 etc.
Brachytherapy is a therapeutic process in which radioactive material is inserted into the body in close proximity to the region affected. The radioactive material emits radiations which are required to control the unwanted biological material in the body. A good application of this is the treatment of cancer using Cobalt-60.
Radioisotope imaging is a diagnostic process which is an imaging technique that may require placing a radioactive material in the body so as to trace or locate the affected part of the body. In this case, the material is used as a tracing element.
The applications that require the placing of radioactive materials in the body are brachytherapy and radioisotope imaging.

1 coulomb of electric charge is carried by 6.25 x 10^18 electrons
1 Ampere = 1 coulomb per second
10 A = 10 coulombs per second
(2.0 x 10^20 electrons) x (coul / 6.25 x 10^18 electrons) / (10 coul/sec) =
(2.0 x 10^20) / (6.25 x 10^18 x 10) sec = <em>3.2 seconds</em>
The gap between the two flasks is partially evacuated of air creating a near vacuum which significantly reduces heat transfer by conduction or convection
Answer:
For number 2 "What do living things need to survive" you could say Food, air, water. I can't think of much more but I believe it's what any basic living thing needs. Also for number 3 all the way on the bottom you can say " A species is classified based on the popularity or kind of living thing, or where it originates from like how there's different types of birds. They all come from the same first species but evolve/change genes differently over time." hope this somewhat helped :)
The answer to fill in the blank in the question above is "make sure that your phone is a hands-free system" based on the paragraph' content<span>. A hands-free system means that a person does not have to use his/her hand for operating the system. A person must use this system if he/she is in the driving situation to avoid a distraction to his/her focus.</span>
