1.What is mean by Adaptation ?
Adaptation refers to the ability of an organism or system to adjust and thrive in changing environments. This process may involve physical, behavioral, or physiological changes, and can occur over the course of generations or within an individual's lifetime. Adaptation is a key component of evolution and survival.
2.What is the main function of digestive system?
The main function of the digestive system is to break down food into smaller molecules that can be absorbed by the body and used for energy, growth, and repair. This process begins in the mouth with mechanical and chemical digestion and continues in the stomach, small intestine, and large intestine. Nutrients are absorbed into the bloodstream and waste is eliminated from the body.
3.Different parts of brain?
The brain is a complex organ composed of different parts that perform various functions. The cerebrum is responsible for consciousness, sensory perception, and voluntary movement. The cerebellum coordinates muscle movement and balance. The brainstem controls vital functions such as breathing and heartbeat. The limbic system is involved in emotions, memory, and motivation.
4.Use of thyriod gland ?
The thyroid gland is a small, butterfly-shaped gland located in the neck that produces hormones essential for regulating metabolism and growth throughout the body. These hormones help control the rate at which the body uses energy, regulates body temperature, and aids in the development and functioning of organs such as the brain, heart, and muscles.
Give one example for each type of immunity ?
• Innate Immunity - Innate immunity is the body's first line of defense against invading pathogens. It is non-specific and provides a general defense against a wide range of pathogens. One example of innate immunity is the skin, which acts as a physical barrier preventing microorganisms from entering the body. Other examples of innate immunity include mucous membranes, stomach acid, and the inflammatory response.
• Adaptive Immunity - Adaptive immunity is a type of immunity that develops after exposure to an antigen. This type of immunity is highly specific and involves the production of antibodies and specialized immune cells. An example of adaptive immunity is the production of antibodies in response to a vaccine. When a person is vaccinated, they are exposed to a weakened or dead form of the pathogen, which stimulates the production of antibodies specific to that pathogen. If the person is later exposed to the live pathogen, their immune system will be able to quickly produce the specific antibodies needed to fight off the infection.
• Passive Immunity - Passive immunity is the transfer of pre-formed antibodies from one individual to another. This type of immunity provides immediate, but temporary protection against a specific pathogen. An example of passive immunity is the transfer of antibodies from a mother to her fetus during pregnancy. These antibodies protect the newborn from certain infections until their own immune system is able to produce its own antibodies.
• Artificial Immunity - Artificial immunity is immunity that is acquired through medical intervention. This includes both active and passive immunity. An example of artificial immunity is , which provides active immunity by exposing the body to a weakened or dead form of the pathogen. Another example of artificial immunity is the use of immune globulin, which provides passive immunity by transferring pre-formed antibodies to an individual who has been exposed to a specific pathogen.
• Natural Immunity - Natural immunity is immunity that is acquired through natural exposure to a pathogen. This type of immunity is not acquired through medical intervention. An example of natural immunity is recovery from a viral infection such as the common cold. Once the body has been exposed to the virus and has developed an immune response, the person is typically immune to that particular strain of the virus.
• Innate Immunity - Innate immunity is the body's first line of defense against invading pathogens. It is non-specific and provides a general defense against a wide range of pathogens.
