I am your usual plant cell There are trillions of my kind on all plant
I am your usual plant cell. There are trillions of my kind on all plants, grass, and trees. My breed ranges from ten to a hundred micrometers. I am approximately twenty micrometers since I dwell in grass. My organelles stretch out to one to ten micrometers. If you are asking what I really do and how I live, I am going to answer them in this paper. First off, any cells requires a structure, metabolism, energy, nutrients, waste, and communication. I am more complex than most other cells. Bacteria

The Ebola VirusA virus is an ultramicroscopic infectious organism that
The Ebola VirusA virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that are know to

Each side is a chain of alternating phosphate and deoxyribose sugar molecules. The steps are formed by bonded pairs of purine-pyrimidin

However one might not consider Hepatitis, because a vaccine has been developed for types of the disease. Hepatitis can be caught and can also be hereditary. It is a disease to which there is no cure for but can be contained. A person may have hepatitis for many years and still not be aware that the

By taking anabolic steroids, a person's testosterone level can be raised up to a hundred times more than the usual amount of 2.5 to 10 mg. Per day. The increase in testosterone increases anabolic activity, which results in greater muscle bulk. It also increases protein synthesis and androgenic activity (enhanced secondary sex
