Carbon dating, or radiocarbon dating, measures the decay of carbon-14 to date organic materials and is not effective for dating zircon crystals. Zircon is a mineral that contains uranium and thorium, not carbon. For zircon, scientists use uranium-lead (U-Pb) dating to determine its age. This method is based on the decay of uranium isotopes into lead isotopes over time. Zircon crystals are exceptionally good at capturing and retaining uranium while excluding lead when they form, making them ideal candidates for U-Pb dating. This technique can date zircons as old as 4.4 billion years, providing crucial information on the earth's early history and the timing of geological events.

Zircon crystals cannot be dated with carbon dating. Carbon dating. also known as radiocarbon dating. is a method of determining the age of organic materials based on carbon 144 decay. Zircon crystals. however. do not contain carbon. The structure of these rocks may contain traces of uranium. so uranium-lead dating is usually used.

Titanium is a chemical element designated by the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is highly resistant to corrosion in sea water, aqua regia, and chlorine. Its most notable properties are its exceptional strength-to-weight ratio, being as strong as some steels but 45% lighter, and its resistance to corrosion, which makes it a principal material in aerospace engineering, military applications, medical devices, and sports equipment. Titanium's ability to withstand extreme environments without rusting or corroding has earned it a reputation as a high-performance material in various industries. Despite its numerous advantages, titanium’s widespread use is somewhat limited by its higher cost compared to common metals like steel or aluminum, due to the complexity of its extraction and processing.

Point mutations, changes in a single nucleotide of DNA, can indeed alter the amino acids in a protein. This happens through the process known as translation, where the sequence of DNA and RNA is used to build proteins. Each triplet of nucleotides, called a codon, specifies a particular amino acid. A change in one nucleotide could change the codon to specify a different amino acid, leading to a change in the protein's structure and function. However, not all point mutations lead to amino acid changes. Due to the redundancy of the genetic code (where multiple codons can specify the same amino acid), some mutations are silent, causing no change in the protein's amino acid sequence. Whether a point mutation changes an amino acid ultimately depends on the specific DNA sequence and the nature of the mutation.
