The plasma membrane or the cell
membrane is the one that protects the cytoplasm of a cell. It is mostly
composed of lipids and proteins. It has a phospholipid bilayer that controls
the entering and exiting of molecules in the cell and at the same time,
provides protection for the cell or plasma membrane. It has polar head and a
nonpolar tail. Proteins embedded within the phospholipid bilayer have the same
function of the plasma membrane that includes selective transport. The
phospholipid bilayer consists mainly of the lipid molecules.
An individual inherits their mitochondrial DNA from their mother.
The little circular chromosome contained inside mitochondria is called mitochondrial DNA. These organelles are the heart of the cell and are present in all eukaryotic cells. The only way for mitochondria and their DNA to be transmitted from mother to child is through the egg cell.
Mitochondrial inheritance: The mitochondria in this particular type of inheritance have their own DNA. Only illnesses resulting from mutations in the mitochondrial DNA are solely passed down through mothers.
Because sperm contain few mitochondria and these break down after fertilization, an individual's mitochondrial DNA is solely acquired from the mother.

Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.
Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
Dextrose and fructose are both types of sugar. the sugar with the best flavor. plenty of whole grains. the starch. called milk sugar.
It is also found naturally in other plant foods such as honey, sugar beets, sugar cane, and vegetables. Fructose is the sweetest naturally occurring carbohydrate, 1.2 to 1.8 times more sweeter than sucrose (table sugar). is the sweetness of Fructose metabolism does not require insulin and has little effect on blood sugar levels. There are many different types of sugar, some more common than others. Fructose, like glucose, is a type of sugar known as a simple sugar or "simple sugar". Monosaccharides can be combined to form disaccharides, the most common of which is sucrose, or "sugar." Sucrose is made up of 50% fructose and 50% glucose. Fructose and glucose have the same chemical formula (C6H12O6), but due to their different molecular structures, fructose is 1.2 to 1.8 times sweeter than sucrose. In fact, fructose is the sweetest natural carbohydrate.
In nature, fructose is most commonly found as a component of sucrose. Fructose is also found in plants as a simple sugar, but that doesn't mean other sugars don't exist.
