The part of our ear which is shaped like a snail shell is cochlea, it is the inner ear that is rolled up into a spiral and it is involved in hearing. The cochlea, meaning snail in greek, So the correct option is ‘Cochlea’.
The stapes is the third of three tiny bones in the middle ear and the one closest to the inner ear. Because of its shape, it’s sometimes called the stirrup.
The rate of blood flow varies greatly between different organs. The liver has the most abundant blood supply with an approximate flow of 1350 ml/min. Kidney and brain are the second and the third most supplied organs, with 1100 ml/min and ~700 ml/min, respectively.
Relative rates of blood flow per 100 g of tissue are different, with kidney, adrenal gland and thyroid being the first, second and third most supplied tissues, respectively.
Calyx is a term used in animal anatomy for some cuplike areas or structures.
Entoprocta, whose name means “anus inside”, is a phylum of mostly sessile aquatic animals, ranging from 0.1 to 7 millimetres (0.004 to 0.3 in) long. Mature individuals are goblet-shaped, on relatively long stalks. They have a “crown” of solid tentacles whose cilia generate water currents that draw food particles towards the mouth, and both the mouth and anus lie inside the “crown”. The superficially similar Bryozoa (Ectoprocta) have the anus outside a “crown” of hollow tentacles. Most families of entoprocts are colonial, and all but 2 of the 150 species are marine. A few solitary species can move slowly.
Bernoulli’s Principle is the single principle that helps explain how heavier-than-air objects can fly. Bernoulli’s Principle states that faster-moving air has low air pressure and slower moving air has high air pressure. Air pressure is the amount of pressure, or “push”, air particles exert. It is this principle that helps us understand how aeroplanes produce lift (or the ability to get into the air).
They are called as imperfect because sexual reproduction is absent in these forms
The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material.
Cosmic rays are energetic, subatomic particles that arrive from outside the Earth’s atmosphere.
Human eye have binocular vision, it means although we have two eye, we perceive single image.
Eye pressure is measured in millimeters of mercury, like the way a thermometer measures temperature using mercury.
