meristems are regions where undifferentiated cells divide
lymphocytes that stay in the blood after the infection is gone
Generalized cells are round or spherical in shape and perform basic life functions. Cheek cells are generalized cells. They are flat, basically round, and protect the inside lining of the mouth.
The word endocardium means the thin, smooth membrane inside the hearts valves and chambers. It is composed of endothelial cells.
lung cancer forms in he lung tissue particularly within the cells that line the air passage it is mainly caused by smoking
Hormones are naturally occurring substances produced by specialized cells that regulate the metabolism or behavior of other cells through signaling. They travel through the bloodstream to reach target cells and exert their effects by binding to specific receptors on the cell surface or inside the cell. Hormones play a crucial role in coordinating various physiological processes in the body.
No, mitose is not a naturally occurring sugar. Mitose is a cellular process of division that leads to the production of two daughter cells with the same number of chromosomes as the parent cell. It is not related to sugars.
Nonliving
Blood types A and B are incompatible because a type A person has naturally occurring Anti-B in his blood and a type B person has naturally occurring Anti-A. Thus a type A person can not receive blood from a type B person because the naturally occurring anti-A would destroy the type A person's red cells. The converse is true for a type B person who can not receive type A blood since the Anti-B found in the type A blood would destroy the type B person's red cells.
Meiosis occurs only in specific cells, such as reproductive cells in plants and animals. It is not constantly occurring in all cells in the body.
It is estimated that there are approximately 100 million yeast cells in one medium-sized apple. Yeast cells are naturally occurring on the surface of fruits and are responsible for fermentation processes.
No known naturally occurring human cells have two nuclei. Cells that have two nuclei, known as bi-nucleated cells, may be observed in specialized cases such as certain cancer cells or muscle cells during development and regeneration.
a biological catalyst that can be found in the cells of your body is called a Enzyme
Currently all known enzymes are naturally occurring, as synthetic enzymes (that display any significant enzymatic activity) are yet to be developed, owing to the fact that the true mechanism of enzyme catalysis is still under some dispute (e.g. enegry traps, WCM model etc).
an enzyme
Minerals are considered abiotic, meaning they are not associated with any living organisms. Minerals are naturally occurring inorganic substances that have a crystalline structure.
when referring to syphilis infection, it is antigenic material such as naturally occurring cardiolipin, lecithin, and cholesterol released from damaged host cells caused by Treponemal pallidum.
