Explanation:
Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal
Cells become haploid in cytokinesis of meiosis one because the chromosomes have divided.
The oldest true fossils are trace fossils called Stromatolites found in Australia, and dated between 3.5 to 3.3 billion years old.
Raphael Baumgartner and their team have finally uncovered evidence of organic matter in the ancient rock formations known as stromatolites found at the Dresser Formation fossil site in the Pilbara region of Western Australia. They detail their findings in a new article published in the journal Geology.
With a variety of methods, including scanning electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, nano-scale secondary ion mass spectrometry, and stable carbon isotope analysis, the researchers examined the samples in thin slices.
According to the team's analyses, pyrite, a mineral with many tiny pores, makes up the majority of the stromatolites. Additionally, the pyrite contains nitrogen-bearing organic material and strands and filaments of organic material that closely resemble the remains of microbial biofilm colonies.

Answer:
Lysosome
Explanation:
Freezer burn occurs due to the sublimation of ice in unprotected meat rich in muscles during long-frozen storage. It appears after thawing. The ice crystals rupture the lysosomes which in turn contain hydrolyzing enzymes.
Leakage of the hydrolytic lysosomal enzyme causes freezer burn and affects the appearance of the frozen meat. The hydrolytic enzymes of lysosomes partially digest the cells which in turn impart bad flavor to the stored food.
