- Question 1 of 7
1. Question
1 pointsCategory: Science and TechnologyEnriched uranium is one in which?
Correct
Natural uranium is 99.284% 238U isotope, with 235U only constituting about 0.711% of its weight. Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased artificially through the process of isotope separation.

2. Question
1 pointsCategory: Science and Technologyatch the following
Isotope Use
- Holmium-166 1. to treat bone cancer
- Iron-57 2. to find tumor in body
- Arsenic-74 3. used in blood as tracer
- Phosphorus-32 4. to treat joint pains
Codes:
Correct
Holmium-166-chitosan complex for the treatment of knee and joint synovitis. The four naturally occurring isotopes of iron, iron-54, iron-56, iron-57, and iron-58 are used primarily as tracers in studies on blood. Arsenic -74 is used to detect the tumours in the human body. Phosphorus-32 is used in radiotherapy in cancer patients.

6. Question
1 pointsCategory: Science and TechnologyNeutrinos are
- tiny particles that carry no charge.
- interact very strongly with electrons and protons.
- high in energy.
- may be produced by the giant black hole at the centre of the Milkyway.
Correct
Neutrinos are tiny particles that carry no charge and interact very weakly with electrons and protons. NASA scientists have found that the giant black hole at the centre of the milkyway may be producing the mysterious high energy neutrinos.
