Dehydration refers to the process of losing or being deprived of water from the body, resulting in becoming dry.

Diffusion is the process in which molecules of a substance move from areas of high concentration to areas of lower concentration. It occurs due to the random motion of molecules and does not require any external energy input. This movement of molecules helps to equalize the concentration of the substance throughout the medium.

Homeostasis refers to the state of balance or stability maintained in the body's internal environment. It involves various physiological processes that work together to regulate body temperature, pH levels, blood pressure, and other vital parameters within a narrow range. This ensures that the body functions optimally and is able to respond to changes in the external environment. Homeostasis is crucial for the overall health and well-being of an organism.

The term "android" means to resemble a man. It is derived from the Greek words "andr-" meaning man and "-oid" meaning resembling or having the form of. An android refers to a robot or machine that resembles a human in appearance and behavior.

Filtration is the correct answer because it involves the separation of particles from a solution by passing it through a filter. This process is commonly used in various industries and laboratories to remove solid particles or impurities from liquids or gases. By using a filter, larger particles are trapped while the filtered liquid or gas passes through, resulting in a purified solution.

The physiological system that includes the lungs, trachea, and pharynx is the respiratory system. This system is responsible for the exchange of oxygen and carbon dioxide in the body, allowing for breathing and the delivery of oxygen to the cells. The lungs are the main organs of this system, while the trachea and pharynx help to transport air to and from the lungs.

The excretory system and the digestive system both play a role in eliminating wastes from the body. The excretory system removes metabolic waste products, such as urea, from the blood and eliminates them through urine. The digestive system breaks down food and absorbs nutrients, while also eliminating indigestible waste material through feces. Therefore, eliminating wastes is a function that is performed by both systems.

Muscle cells require a large amount of energy for contraction. Mitochondria are the powerhouses of the cell and are responsible for generating energy in the form of ATP through cellular respiration. Therefore, muscle cells would typically contain more mitochondria to meet their high energy demands compared to liver cells, which have different functions and do not require as much energy for their activities.

Karyogenesis refers to the formation of a cell's nucleus. It is the process by which a cell's nucleus is formed during cell division. This involves the replication and condensation of the cell's chromosomes, which contain the genetic material in the form of DNA. Karyogenesis is a crucial step in the cell cycle and is essential for the proper functioning and development of an organism.

Organic refers to compounds that contain carbon or anything that is derived from vegetable or animal forms of life. In contrast, inorganic refers to compounds that do not contain carbon and are not derived from living organisms. Organelle refers to a specialized structure within a cell that performs a specific function, while an organ refers to a group of tissues that work together to perform a specific function in an organism.

Perfusion refers to the process of pouring through. It typically refers to the passage of fluid through the circulatory system to supply oxygen and nutrients to the body's tissues. In this context, perfusion can be seen as the process of pouring blood through the blood vessels, ensuring that all cells receive the necessary substances for their function.

Protoplasm refers to the essential matter of a living cell. It is the living substance that encompasses the cytoplasm and nucleus of a cell. Protoplasm contains various organelles and is responsible for carrying out the cell's functions. It is essential for the cell's survival and plays a crucial role in maintaining its structure and carrying out metabolic processes. The other options, phenotype, chromosome, and cilia, do not specifically refer to the essential matter of a living cell, making them incorrect answers.

The term "somatotrophic" refers to the stimulation of body growth. This term is derived from "soma," which means body, and "trophic," which means nourishment or stimulation. Therefore, somatotrophic is the correct answer as it specifically relates to the stimulation of body growth.

Epithelial tissue is specialized to cover the inner and outer surfaces of the internal organs. It forms a protective barrier that helps to prevent damage and infection. Epithelial tissue is made up of tightly packed cells that are arranged in layers and can be found in various forms such as squamous, cuboidal, and columnar. It also has the ability to secrete and absorb substances, making it essential for the proper functioning of organs and maintaining homeostasis within the body. Connective tissue, muscle tissue, and nervous tissue have different functions and are not specialized for covering surfaces like epithelial tissue.

The correct order of organization of all living things from simplest to most complex is as follows: Atom -> molecule -> organelle -> cell -> tissue -> organ -> organ system -> organism. This order starts with the basic building block of matter, the atom, and progresses to more complex structures such as molecules, organelles, cells, tissues, organs, organ systems, and finally, the complete organism.

The correct answer is "Digestion of macromolecules and old organelles". Lysosomes are responsible for breaking down and digesting macromolecules and old organelles within the cell. They contain enzymes that can break down various types of molecules, such as proteins, carbohydrates, and lipids. This process helps to recycle and reuse cellular components, as well as eliminate waste materials. Therefore, if an organelle found in a liver cell is primarily involved in the digestion of macromolecules and old organelles, it would be best identified as a lysosome.

Blood, bone, and cartilage are examples of connective tissue because connective tissue is a type of biological tissue that provides support, structure, and protection to the body. It connects and binds different organs and tissues together. Blood is a fluid connective tissue, bone is a specialized connective tissue that provides structural support, and cartilage is a flexible connective tissue found in various parts of the body. Therefore, all three examples mentioned are types of connective tissue.

Connective tissues include tendons that connect muscle to bone. Tendons are strong, fibrous tissues that attach muscles to bones, allowing for movement and stability. They are responsible for transmitting the force generated by muscles to the bones, enabling us to perform various physical activities. Other connective tissues mentioned, such as the layer beneath the skin that connects it to muscle and fat, are not specifically responsible for connecting muscle to bone. Therefore, the correct answer is tendons that connect muscle to bone.

The primary difference between endomorph, mesomorph, and ectomorph is their shape, which can be round, slender, or well-proportioned. Additionally, the difference also lies in the layer of embryonic cells from which the body is formed.
