Stem cells are cells have not undergone differentiation!
<span>Connective tissue supports the framework of the liver, and epithelial tissue protects the liver.
Connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver.
Connective tissues are mainly used in forming support networks within tissues and Epithelial tissue tend to line the organs and form protective cell layers.</span>
While both carbohydrates and lipids are made up of carbon, hydrogen and oxygen there are several differences:
1. Carbohydrates are chains of 2 or more carbon atoms. These can be very lengthy (like long cellulose chains of glucose units). They have many polar OH groups (e.g. glucose - C6H6O6). Most carbohydrates are hydrophilic and are soluble in water because of their polar OH groups. They are not necessarily sugars nor are they necessarily sweet. They are also important components of DNA, RNA and ATP.
2. Lipids are more diverse in their chemistry. They generally have a polar region at one end (this end attracts water) and a large non polar hydrocarbon region that repels water. Lipids don't dissolve in water and instead clump together with their hydrocarbon regions on the interior. Lipids include oils, fatty acids, waxes, steroids and hormones.
Independent ( because the reading relies on the different cuffs ) making this a reliable yet invalid experiment. It’s reliable because it consistently differed by 15 points each different cuff. Invalid because the readings were constant with the correct cuff, putting the incorrect cuff size can cause inaccurate readings
