Ketone-1,5-diphosphate carboxylase oxygenase (chemical reaction 3D schematic diagram)
Rubisco is one of the most abundant enzymes in nature, playing an important role in carbon fixation and photorespiration processes. Specifically, Rubisco participates in the dark reaction process after the light reaction in the photosynthetic reaction, catalyzing the carboxylation of ribulose-1,5-diphosphate (RuBP) and then cleavage to form two glycerol-3-phosphate (PGA) molecules. This reaction is a crucial step in the Calvin cycle.

Hacker Bird (Restoring 3D Model)
Phorusrhacidae is a large carnivorous bird species. The closest relative to them today is the crane family. The terror bird, also known as the terror bird, is a bird like carnivorous animal that lived alone during the same period as the saber toothed tiger. It is about 1-3 meters tall. Terror birds have hard leg bones and strong muscles, which can completely crush the bones of medium-sized prey and slowly feed on the nutrient rich bone marrow in the prey's bones. According to scientists' estimates, terror birds can reach speeds of up to 97 kilometers per hour, and the extinction of terror birds is believed to be related to wolf packs and disasters.

Migvie Kirk Monument in Aberdeenshire
Migvie Kirk is located on a small road northwest of Tarland in Aberdeenshire. This irregularly shaped stone is made of gneiss and is 2.1 meters high. The front of the stone faces east, away from the gate you just walked through. The front is mostly occupied by carved crosses and decorative patterns. The outline of the cross is unusual, with four arms intersecting at the center. The upper corner is carved into the shape of a metal ring, as if this cross is a pendant depiction. Appropriate lighting and a little imagination are needed to see clearly, but there are other carvings on the area left by the angle of the cross.
Lunar probe 25
In October 1998, Russian Academy of Sciences academician Galimov proposed the concept of conducting another lunar exploration mission after Luna 24 at the Moscow International Lunar Exploration Conference, which is regarded as the beginning of modern Russia's return to the moon program. However, based on budget constraints, the authorities have listed the Phobos Earth probe and the Spectral Astrophysics Observatory as higher priority tasks, and lunar exploration has been temporarily put on hold. In early 2018, the Space Research Institute of the Russian Academy of Sciences announced that the probe was scheduled to be launched in 2019 and a possible landing site had been selected.

Dodo Bird (3D Restoration Model)
The dodo bird (Raphus cuculatus) is an extinct bird species in the pigeon family of the pigeon order. The body shape is comparable to that of a swan, and there are also obvious sexual dimorphism. Body length 70-90 centimeters, weight 17-28 kilograms. It is a large bird with a plump body, covered with soft gray feathers, which are brown or gray in color. The female bird has lighter fur than the male bird. There is a white feather on the tail. Their wings are too small and weak to lift the Dodo off the ground. Because they cannot fly, the female bird lays one egg at a time, which is co hatched by the female and male birds. Eating fruits and seeds.

Allosaurus skeleton
Allosaurus is one of the most famous large carnivorous dinosaurs, occupying the top of the food chain in late Jurassic terrestrial ecosystems. Its model species, the fragile Allosaurus, was created by the great American paleontologist Osnil in the 20th century Marsh described the naming in 1877. They are also the most abundant and widely distributed predators discovered in the Late Jurassic period. Adult Allosaurus can grow up to 9 meters in length, with a few individuals believed to reach up to 12 meters. Although not as robust as the Tyrannosaurus rex, the body proportions of the Allosaurus are more symmetrical, with more developed forelimbs, making it appear more agile.
Earth 3D Animation Model
It is the third planet in the solar system, a vibrant and beautiful planet with a unique blue appearance and abundant natural resources. With a diameter of approximately 12742 kilometers, it has the only known environment in the solar system with widespread liquid water. Most of these water resources are concentrated in the oceans on Earth, forming the well-known 'Blue Planet'. The atmosphere is mainly composed of nitrogen and oxygen, suitable for biological respiration. It is the home of humanity. Human civilization has developed a rich and diverse culture, technology, and social structure on Earth. Earth is the only known planet in the universe capable of nurturing and sustaining life.

King Gustav Vasa's gilded crown helmet
The gilded crown adopts a medieval style, symbolizing Gustav Vasa as both a part of the old alliance and a part of the newly established hereditary monarchy. The helmet was used at Gustav Vasa's funeral in 1560, when witnesses mentioned a helmet decorated with a gilded crown. The helmet was purchased for the king by Klaus Heigel, the king's agent, in Augsburg.

Terror bird skeleton
The terror bird is a bird of the ostrich order, terror bird family. The abdominal feathers are yellow, and the other parts are yellow and black in color. Enlarged body, degeneration of upper limbs, and short and thick lower limbs; The neck is covered with feathers and is relatively short; There are three toes. In 1843, it was named the terror bird by Owen, meaning a large bird that can scare people. The terror bird inhabits the primitive lowlands and coastal forest grasslands of the southern islands of New Zealand. Living as a couple, each pair has their own territory. Cannot fly and run slower than ostriches. They feed on berries, grass seeds, and roots, as well as some insects. Only one egg is laid per reproduction, no nest is built, and the egg is laid in a concave area on the ground. The egg is about 250 millimeters long and 180 millimeters wide.
Roman currency Denar
Denarius is an ancient Roman silver coin that was first introduced around 211 BC. Widely used during the Roman Republic and Roman Empire, it became the main currency unit at that time. Octavianus, later known as Augustus, was the first emperor of the Roman Empire and ruled from 27 BC to 14 AD. On the Denard coins issued between 44 BC and 27 BC, his portrait and various symbols of Roman power and victory were usually engraved.

Roman currency Antoninian
Antoninianus is a silver coin from the Roman Empire period, introduced by Emperor Caracalla in 215 AD. Although its face value is two Denarius, its weight is much lower than that of two Denarius. Antoninian initially contained about 49.5% silver, but over time its silver content continued to decrease, reaching only 2.5% silver by 274 AD.
Ancient Kikushi (3D Restoration Animation)
Kikushi, a collective term for cephalopods and ammonites in the phylum Mollusca, is a group of extinct marine organisms. Kikushi lived from the early Devonian to the late Cretaceous period, and its shell is often preserved in the form of fossils in the strata. The outer shell of ammonite is a single petal, consisting of three parts: the fetal shell, the gas shell, and the living room. It usually spirals around the fetal shell along a plane, with each revolution forming a spiral ring. Adult ammonite shells generally have 5 to 9 spiral rings, symmetrical on both sides, and can be straight, curved, or even irregular.
