Patients with some forms of cancer receive bone marrow transplant as treatment. What type of bio technology is this treatment

In patients with cancer, such as leukemia, bone marrow transplantation is a type of medical biotechnology, specifically stem cell-based biotechnology.

Explanation:

Biotechnology is the application of technological tools to influence biological processes, allowing their use in medicine for the purpose of research and development of medical therapies.

Bone marrow is found inside bones and is characterized by the presence of stem cells, which are necessary for the formation and constant renewal of blood cells.  Biotechnology has succeeded in separating these stem cells and using them to treat diseases such as cancer and leukemia. Bone marrow transplantation is one of these treatments.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

the answer is trees if i'm not mistaken
