    Cryptography involves creating written or generated codes that allow information to be kept secret. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without unauthorized entities decoding it back into a readable format, thus compromising the data.

    An acoelomate is an invertebrate with three germ layers that lack a body cavity or a coelom. That means acoelomates do not possess a fluid-filled cavity between the body wall and the digestive tract.A coelomate is either a triploblastic vertebrate or invertebrate with bilateral symmetry that possesses a true coelom. Coelomates are also called eucoelomates. A coelom is a fluid-filled cavity, which lies between the body cavity and the gut. It develops from the mesoderm.A pseudocoelomate is an organism with body cavity that is not derived from the mesoderm, as in a true coelom, or body cavity. A pseudocoelomate is also known as a blastocoelomate, as the body cavity is derived from the blastocoel, or cavity within the embryo.

    Bryophyta can live on both land and water

    0Thank You

    Yogita Ingle 7 years ago

    1. Monoecious is a condition where a single plant produces both male and female flowers which are helpful in fertilisation process. Coconut palm produces both male and female flowers in a single individual.
    2. Amphibians are those organisms which live on both land and in water. Bryophytes are called amphibians of the plant kingdom because these plants though live in soil but they need water for sexual reproduction. The sperm of bryophyte (antherozoids) are flagellate and need water to swim to the eggs. In other words, as these plants need water for reproduction unlike other plants, they are called as amphibians.

    The Principle states that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.”
    Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”
    Thus, when a solid is fully immersed in a liquid, it loses weight which is equal to the weight of the liquid it displaces.

    Maxwell’s right hand rule:

    Imagine that you are grasping the current carrying wire in your right hand so that your thumb point in the direction of current, then the direction in which fingers encircle the wire will give the direction of magnetic field lines around the wire. Let AB be the wire carrying current, to find out the direction of the magnetic field of AB. Imagine that you are grasping the current carrying wire in your right hand. The direction in which our fingers are folded gives the direction of magnetic field lines.
