Which of the answer choices provides an accurate example of how knowledge of nuclear reactions has been used to benefit society select all that apply.

1.Radiation in correct doses may be able to prevent and treat illnesses caused by viruses, such as HIV and influenza.

2. Nuclear fusion can be easily activated and controlled in nuclear power plants and harnessed to generate clean electricity.

3. Controlled fission chain reactions can be used to produce electricity in a nuclear-powered submarine.

4.Medical imaging devices use radioactive elements with short half-lives to see through the human body and diagnose patients.

Controlled fission chain reactions can be used to produce electricity in a nuclear-powered submarine.

4.Medical imaging devices use radioactive elements with short half-lives to see through the human body and diagnose patients

Explanation:

A submarine uses nuclear vision as a source of energy. The heat from controlled nuclear fission reactions produces steam which drives a steam turbine to power the submarine.

In the area of medicine, medical imaging is becoming a popular technique for diagnosis of many illnesses. These radioactive elements with short half lives are used to see through the human body for the purpose of diagnosis.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
