  The vaquita is a species of porpoise endemic to the northern end of the Gulf of California in Baja California, Mexico. Averaging 150 cm or 140 cm in length, it is the smallest of all living cetaceans. Vaquita, the world's rarest marine mammal, is on the edge of extinction. The plight of cetaceans—whales, dolphins, and porpoises—as a whole is exemplified by the rapid decline of the vaquita in Mexico, with about 10 individuals remaining. This little porpoise wasn't discovered until 1958 and a little over half a century later, we are on the brink of losing them forever. Vaquita are often caught and drowned in gillnets used by illegal fishing operations in marine protected areas within Mexico's Gulf of California. The population has dropped drastically in the last few years. The vaquita has a large dark ring around its eyes and dark patches on its lips that form a thin line from the mouth to the pectoral fins. Its top—the dorsal surface—is dark gray, its sides are pale gray, ...

The ear is a complex and intricate sensory organ responsible for both hearing and balance. It plays a crucial role in our daily interactions with the world around us. Comprising three main parts - the outer ear, middle ear, and inner ear - it converts sound waves into electrical signals that our brain interprets as sound, while also helping us maintain equilibrium and spatial orientation. Outer Ear: The outer ear consists of the visible part known as the pinna or auricle and the ear canal. The pinna helps in collecting and directing sound waves into the ear canal. Sound waves travel through the ear canal, where they eventually reach the eardrum (tympanic membrane). Middle Ear : Beyond the eardrum lies the middle ear, an air-filled cavity. Three tiny bones called the ossicles, are housed here: the malleus (hammer), incus (anvil), and stapes (stirrup). These bones amplify and transmit sound vibrations from the eardrum to the fluid-filled inner ear. The Eustachian tube, another important...

 OPTICAL ILLUSIONS The brain's task is to make sense of what the eyes see, and it usually gets it right. However, optical illusions can play tricks on the brain as it tries to fill any gaps in the visual information it receives.

 Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function.

 The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.   Physics, Special relativity, Principle of relativity Einstein's Theory of General Relativity states that ________________. Correct answer gravity and acceleration are equivalent.

 Kinematics is the branch of classical mechanics that describes the motion of points, objects and systems of groups of objects, without reference to the causes of motion (i.e., forces ). The study of kinematics is often referred to as the “geometry of motion.”

 Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron. Mass: 1.67492749804(95)×10−27 kg; 939.56542052(54) MeV/c2; 1.00866491588(49) Da Electric charge: 0 e; (−2±8)×10−22 e (experimental limits) Interactions: gravity, weak, strong, electromagnetic Composition: 1 up quark, 2 down quarks Statistics: fermionic Classification: baryon Antiparticle: antineutron

 Antiparticle, subatomic particle having the same mass as one of the particles of ordinary matter but opposite electric charge and magnetic moment. Thus, the positron (positively charged electron) is the antiparticle of the negatively charged electron. Every type of particle has a corresponding antiparticle, for example; the positron is the antiparticle of the electron. the antiproton is the antiparticle of the proton. the antineutron is the antiparticle of the neutron. the antineutrino is the antiparticle of the neutrino.

 Electron revolves around the nucleus of an atom  The electron is a subatomic particle, whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. Discovered: J. J. Thomson (1897) Symbol: e−, β− Magnetic moment: −1.00115965218091(26) μB Electric charge: −1 e; −1.602176634×10−19 C; −4.80320451(10)×10−10 esu Generation: First Family: Lepton Antiparticle: Positron

 A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".  Mass: 1.67262192369(51)×10−27 kg; 938.27208816(29) MeV/c2; 1.007276466621(53) Da Symbol: p, p+, N+, 1; 1H+ Electric charge: +1 e; 1.602176634×10−19 C Charge radius: 0.8414(19) fm Composition: 2 up quarks (u), 1 down quark (d) Electric dipole moment: < 5.4×10−24 e⋅cm Electric polarizability: 1.20(6)×10−3 fm3

 Atomic nucleus  The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.  They are in middle of an atom

 A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.

 An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons. Atom is the smallest particle  It can't be break down or destroyed

 Carbonization is the conversion of organic matters like plants and dead animal remains into carbon through destructive distillation.  Coal is formed from it
