Asked in Genetics
What is a Protective outer covering of all cells that regulates the interaction between the cell and the environment?
It is a cell wall that surrounds the cell outside its cell membrane
Asked in Biology, Medical Terminology
What is the medical term meaning white protective covering over nerve cells?
The protective covering over some nerve cells is called the myelin sheath. ...
Asked in Chemistry, Biology
Are Epithelial cells a class of organic molecules?
No. Epithelium is a protective layer of cells typically covering the outside of an organ or the lining of the wall of a cavity in the body. All body cells need organic molecules to provide energy for building proteins, lipids, and other organic molecules. ...
Asked in Multiple Sclerosis
How do you get Multiple Sclerosis?
Multiple sclerosis is caused by damage to the myelin sheath, the protective covering that surrounds nerve cells. When this nerve covering is damaged, nerve impulses are slowed down or stopped. Multiple Sclerosis is caused by damage to the myelin sheath, the protective covering that surrounds nerve cells. When this nerve covering is damaged, nerve impulses are slowed down or stopped. Researchers are not sure what triggers the inflammation. The most common theories point to a virus or genetic defect, or a combination of...

What is the protective outer covering around all cells?
It is the cell membrane. Plant cells also have a rigid structure called a cell wall. ...
Asked in Science, Biology, Biochemistry
Does human cells use lipids for energy storage and protective covering?
Yes. Lipids are found in the protective coating of the cell membrane of cells. They are also used to store chemical energy, as we synthesize fat polymers from fatty acids / triglycerides. ...
Asked in Embryology
What membranes form a protective sac that surrounds an embryo?
trophoblast cells i.e the outer cells of blastocyst(1st embryonic stage in man) gives rise to amnion chorion allantois and yolk sac the 4 protective layer of embryo and inner cells called embryoblast gives rise to embryo ...
What distinct characteristic of Epithelial Tissues make them excellent for covering and lining of body organs?
Cells are flat , closely attached , dead or dying , protective .

Why do Viruses have more difficulty entering plant cells than animal cells because?
It could be because of the protective cell wall covering the plant cells. Animal cells only have plasma membranes and could be more prone to viral infection. ...
