Spinal Cord
(I think...if it not, I'm sorry)
Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.
A nurse researcher analyzed trends in obesity data in the United States and data globally. The statistics determined by nurses regarding the epidemiology of obesity include:
- Over 600 million adults have obesity worldwide
- The prevalence of obesity has more than doubled since 1975
- The prevalence of obesity in the United States is the highest in the world
<h3>
</h3>
The United States (US) is the country with the highest obesity rate in the world. This makes the US government make obesity a problem that needs to be considered, for the health of its citizens. In recent years, health observers have categorized obesity as the spread of a deadly disease.

Answer: Memory cells.
Explanation:
Vaccines are effective because they lead to the production of memory cells which remembers the experience when the body got an exposure to the antigen for the first time.
When the antigen get exposed to the body, B cells of the body are activated. They further get divided into two parts, one part forms plasma cells and the other part forms memory cells.
The plasma cells secrete antibodies in the blood to fight disease and other part gets stored in the lymph until it is exposed for the second to antigen which will convert them into plasma cells.
The reserved cells are known as memory cells.
