A vestigial organ is an organ that has no beneficial use to an organism. Ex. Tail bone in Humans
Ill give you 3:skeletal,nervous,and muscular
Proteins, Lipids, Nucleic Acids, and Carbohydrates.
Your question is too broad to give you a specific answer but I'll give you some different ways the body can be organized by structure. The first is by complexity where atoms > molecules > cells > tissues > organs > organ systems > organism. Within each of those you find different organizations. For example, tissues can classified as epithelial, connective, muscular, or nervous tissue. Similarly, there are generally considered to be 11 different organ systems in the body, e.g. the endocrine system or the integumentary system.
No. Single celled organisms such as amoeba obviously don't have them. Slightly more complex organisms such as sponges don't have organs or organ systems though they might be said to have tissues.
The reproduction system, the digestive system, the immune system.
Well, an example of an organ would be, say, the kidneys. However, they are just on part of the excretion system, which includes the intestines, the bladder, the rectum, and to a smaller extent the skin. In other words, an organ system is made up of different organs and is hindered when one is damaged.
The levels of organization of life are cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems. For example, cells are the basic unit of life (e.g., red blood cells, nerve cells), while tissues are groups of cells working together (e.g., muscle tissue, nerve tissue). Organs are structures composed of tissues with specific functions (e.g., heart, lungs), while organ systems are groups of organs working together to perform a particular function (e.g., digestive system, respiratory system).
A vestigial organ is a structure in an organism that has lost most or all of its original function through evolution. An example is the human appendix, which is believed to be a remnant of a larger cecum found in our evolutionary ancestors.
Organ adoptions involve the legal transfer of organs from one person to another for the purpose of transplantation. This process helps individuals who are in need of an organ transplant to receive a donated organ from a willing donor, often to replace a failing organ in the recipient's body. Organ adoptions are regulated by medical authorities and require strict procedures to ensure the safety and efficacy of the transplant procedure.
