14 million year old scorpionfish fossils

Scorpion fish is one of the most venomous and inconspicuous fish species in the ocean. These ambushing predators are experts in integrating into the environment, sitting patiently at the top of coral reefs waiting for unsuspecting prey to swim over. The color of scorpionfish ranges from dull brown and yellow to bright red and orange, perfectly matching the surrounding coral and even exhibiting feather like fins or flaps to better camouflage with neighboring corals.

Vibrio cholerae

Vibrio cholerae (Vibrio cholerae) is a gram-negative bacteria, the bacteria is short and comma-shaped, with a single flagellum, pili, part of the capsule. It is divided into 139 serogroups, of which O1 group and O139 group can cause cholera. Vibrio cholerae is the pathogen of human cholera, cholera is one of the ancient and widespread infectious diseases.

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.

Western European bison skeleton

The Western bison is a member of the family Oxidae in the order Artiodactyla. The body length is 220-300 centimeters, the tail length is 40-60 centimeters, and the weight is 450-1000 kilograms. Both female and male animals have horns, which are slender and elongated. The horns first turn inward, then turn upward, and then bend forward. The tips of the horns then bend inward. Female animals have shorter and thinner horns. Small head, exposed snout, small eyes, and short ears. The neck is relatively short, with obvious hanging hair from the lower cheeks to the chest.

normal red blood cells versus sickle-shaped red blood cells

Sickle cell anemia, also known as sickle cell anemia and sickle cell anemia, is a hereditary hemoglobinopathy. The amino acid glutamic acid at the 6th position of the β-peptide chain is replaced by valine, which forms sickle hemoglobin and replaces normal hemoglobin. The clinical manifestations are chronic hemolytic anemia, predisposition to infection, and recurrent pain crisis causing chronic ischemia leading to organ and tissue damage. Mainly through blood transfusion, drug treatment and other methods of treatment.

Sea Lion Skull

Sea lion (Sea Lion) is a semi-aquatic mammal in the family Sea Lionidae, which has become a landmark species in marine ecosystems due to its foldable flippers, outer ear structure and social habits. There are 7 genera and 15 species in the world, which are widely distributed in temperate to tropical waters, and are the key link between marine and terrestrial ecology. It is mainly distributed in the North Pacific Ocean, temperate waters of the southern hemisphere and some tropical waters; it inhabits coastal rocky areas, sandy beaches, rocks or floating ice edges, and prefers shallow seas with water depth <100 meters. Mainly to fish, cephalopods and crustaceans for food.

Rhino Skull

The rhinoceros (Rhinoceros) is a large herbivorous animal in the family Mammalia (Mammalia), hoyhooe (Perissodactyla), rhinoceridae (Rhinocerotidae), known for its iconic horns and heavy skin. Five species of rhinoceros (belonging to four genera), all of which are endangered, are facing a severe survival crisis due to habitat destruction and poaching.

Fossil skeleton of Procaratops

An's protoceratops is a herbivorous dinosaur of the ornithophorosaurid family, which is one of the most representative early horatosaurs in the late Cretaceous. The discovery of its fossils provides key evidence for the study of the evolution and paleoecology of the species, and is known as the "ancestor of the horned dragon". It is mainly found in the Late Cretaceous strata of South Gobi Province, Mongolia; a few fossils are found in Inner Mongolia, China. Inhabit arid to semi-arid grassland or desert environment, prefer low-lying, sparse vegetation area.

calcite

Calcite chemical formula for CaCO, is the most widely distributed carbonate minerals in nature, belongs to the trigonal system (rhombohedral system), because the crystal is often a rhombohedral (rhombohedral) morphology and named. Its English name "Calcite" is derived from the Latin "calx" (meaning lime), which is the main component of limestone and marble.

lazy bear specimen

The lazy bear is a mammal of the genus lazy bear in the order Carnivora, with a black body, rarely dark brown or reddish brown, a crescent-shaped white spot on the chest, and a light-colored nose and face. The hair is long and messy. Under feeding conditions, life can reach 40 years. The sloth bears are found in Sri Lanka, India, Nepal and Bhutan. It inhabits early and humid forests, shrubs, savannas and grasslands, mostly below 1500 meters above sea level, and occasionally up to 2000 meters above sea level, such as the Western Ghats in India. It feeds mainly on termites, but also on small vertebrates, fruits, and insects.

Actinoceras

It is an ancient marine organism belonging to the subclass Nautilus in the order Cephalopoda, and its fossils are mainly found in the Ordovician strata. One of its prominent features is that the outer shell is straight and the body tube is prominent, with flat and wide body tube sections resembling beads. The structure of the neighboring wall is complex, with the neck of the neighboring wall bending outward at an angle of approximately 45 degrees. There is calcium filling inside the body tube, which is an important basis for paleontologists to study its classification and evolution. Widely distributed, it has been found in Asia and North America, especially in the Ordovician strata of northern China. Understanding ancient marine ecosystems and geographical environments holds significant scientific value.

Joule Meter Principle Experiment (3D Experimental Animation)

In 1847, Joule designed a more ingenious experiment by placing water in a calorimeter, installing a rotating shaft with blades in the middle, and then letting a descending weight drive the blades to rotate. Due to the friction between the blades and water, both the water and the calorimeter heated up. Based on the height of the heavy object falling, the converted mechanical work can be calculated; Based on the temperature rise of water in the calorimeter, the increase in internal energy of water can be calculated. By comparing two numbers, the accurate value of thermal energy equivalent can be obtained.
