Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.
When was BSE first discovered?
BSE first appeared in British cattle in the mid-1980s. There have been numerous cases detected in other countries. A complete list of countries is available from both the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
Lactose, or milk sugar, is composed of one glucose unit and one galactose unit. It can be classified as a disaccharide.
<h3>What is
disaccharide?</h3>
Any material made up of two simple sugar molecules (monosaccharides), coupled to one another, is referred to as a disaccharide, often known as double sugar.
A disaccharide (also known as a double sugar) is the sugar that results from the glycosidic connection of two monosaccharides (simple sugars). Disaccharides are water soluble, just as monosaccharides. The sugars sucrose, lactose, and maltose are three typical examples.
Disaccharides. Two monosaccharide units are joined by glycosidic linkages in either the or orientation to form disaccharides. Sucrose, lactose, and maltose are the three most significant ones.

Explanation:The main functions of polysaccharides in plants are the protection and energy. If you look carefully, plant cell walls are made up of cellulose and hemicellulose. These two are the major plant polysaccharides that provide rigidity and physical strength the cell wall and the whole plant. :)
Its called osmosis and it only happens with water. now I'm just adding words to be able to post this. its moving down the concentration gradient.
