Question

Which scientific discipline best links the use of titanium and plastics in artificial bone and joint replacements? physics chemistry biology materials

Answer 1

Answer;

Biology

Explanation;

• Biology is the scientific discipline that best links the use of titanium and plastics in artificial bone and joint replacements. This is done in medicine which is a branch of biology.
• For example the ball and the socket of the hip joint are replaced with a metal implant, and a plastic spacer is placed in between. The most commonly used metals used include titanium and stainless steel.
• Titanium is often used in the body because of its biocompatibility and, with surface modifications, bioactive surface. The strong and corrosion-resistant properties of titanium make it reliable and biocompatible.

Answer 2

Correct answer choice is :

B) Chemistry

Explanation:

Advanced titanium-based compounds have been also used for some years for extremely stressed femoral segment stalks. Both metal samples present a higher impedance to pitting, crack, and galvanic corrosion, stress corrosion weakening and corrosion burnout than polished stainless steel of comparatively low power properties. For this purpose, the low element power of hip prostheses made of the recent stuff is paid for by a larger cross-section of the prosthetic stem, this depending on the geometric situations of the femur.
