Answer:
The first historical use of biomaterials dates to antiquity, when ancient Egyptians used sutures made from animal sinew. The modern field of biomaterials combines medicine, biology, physics, and chemistry, and more recent influences from tissue engineering and materials science.

Carbon film fossil is the type of fossil that preserves delicate details of an organism after pressure squeezes out liquids and gases.
Carbon film fossil is a type of fossil that is mainly composed of carbon and can preserve delicate details of organism’s (animal and plants) parts. The formation of carbon film fossil starts when a dead organism is buried under sediments. After some time, the organism will begin to decay in a process known as carbonization. Pressure will squeeze out liquids and gases from the dead organism, leaving behind a layer of carbon. Carbon film fossils usually appear black or brown in colour.
Loss of Rb, an important part of the G1-S transition checkpoint, can result in uncontrolled cell cycle progression and cancer. All of the following would mimic loss of Rb except constitutively active Ras GTPase activating protein. Correct answer: letter E.
Constitutively active Ras GTPase activating protein would not mimic loss of Rb, because it would not directly result in uncontrolled cell cycle progression.
<h3>What is Retinoblastoma (RB)?</h3>
Rb is an important tumor suppressor protein that works to inhibit cell cycle progression by preventing the activation of E2F transcription factors. Constitutively active Ras GTPase activating protein would not directly interfere with the Rb-E2F pathway, which is necessary for uncontrolled cell cycle progression and cancer.
