Answer:
The correct answer is -
a cell that is able to develop into a variety of specialized cells
a specialized cell that results in differentiation
a specialized cell that results in self-renewal
Explanation:
Stem cells are the primal cells that have the ability to self-renewal and able to differentiate into more specialized cells through the mitotic cell division. Stem cells are pluripotent generally but can be totipotent and multipotent as well.
These cells show self-renewal and unlimited potency properties. Self-renewal is the ability of the cell that allows it to go through various cell cycles without losing its undifferentiated state.
I believe they are positioned Beneath one of the clavicles. Pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate. Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of heartbeat.
1. Proteins are made from subunits called amino acids. There are 20 different amino acids which are responsible for the variation of proteins. Those amino acids are linked together by peptide bonds and form polypeptide chains. According to the polypeptide structure, there are 4 levels in protein structure as primary structure, secondary structure, tertiary structure and quaternary structure.
2. Starch is a type of carbohydrate. Hence, the subunits of starch are sugar molecules which are called as glucose. The elements of glucose are C,H,O. By linking glucose units with 1-4 alpha glycosidic bonds, the polysaccharide chain is formed. Hence, starch is also a polysaccharide<span>.

3. DNA is made from subunits called nucleotides. Nucleotides consist of deoxyribose, phosphate group and nitrogenous base.
There are two types of nitrogenous base as purines and pyrimidines. Adenine (A) and guanine (G) are purines and
thymine (T) and cytosine (C) can be seen as pyrimidines. Those nucleotides are linked together by sugar phosphate bonds which are formed between 5' phosphate group and 3' -OH group<span>.</span><span>
