Before the process begins, there must be an organ that is available. People who give organs, known as organ donors, usually donate a kidney if they are very healthy. People who that are brain dead, meaning the person is dying because brain is dead but the rest of the body is fine, first you will need to have sex can have there organs, like there heart and liver, can be removed. The organs are preserved and can be put into another body by the time the organ dies. People who need the organ are on a list, and the person at the top of the list will get the organ if it is right for them. There will be an operation and the body must take the organ. If not the body will reject the organ, sending white blood cells to kill the organ.
The process by which modern organisms have descended from ancient organisms is called evolution.
Organisms remove metabolic cellular wastes by the process of excretion.
The process by which modern organisms have descended from ancient organisms is called evolution. This process involves changes in the genetic makeup of populations over successive generations, leading to the diversity of life forms we see today.
Plants, algae, and some bacteria are organisms that go through the process of photosynthesis.
Organisms need to carry out the process of respiration because the cells in the organisms break down simple food molecules and release their energy.
Darwin said that organisms evolve through the process of natural selection.
Reproduction
They are called phototrophs. They are photosynthetic organisms
The process by which humans breed organisms to obtain certain traits is known as artificial selection.
The primary organisms involved in the process of photosynthesis are plants, algae, and cyanobacteria. These organisms contain chlorophyll, a pigment that absorbs sunlight, to convert carbon dioxide and water into glucose and oxygen. This process is essential for producing the oxygen we breathe and providing energy for many living organisms.
reproduction
Most organisms develop through a process that starts with the fertilization of an egg
