Answer:
units of C 6 H 12 O 6
Explanation:
Starch is a polymer of billions of glucose units joined through a condensation reaction that splits out molecule of water. Starch is an important part of our food belonging to the category of carbohydrates. It is found in cereals and potatoes.
Starch can be in two forms based on the their structure and some other differences:
1) Amylose- straight chain polymer
2)Amylopectin- Branched chain polymer
You can see the structure of starch with glucose monomers for better understanding in the image.

Answer: Poly(ethene) has a higher melting point than ethene. The reason can be seen in the explanation below.
Explanation:
Ethene is one of the most important alkene hydrocarbons which is one of the main products obtained during the cracking of the gas oil fraction of petroleum.
Polymerization is a process whereby two or more simple molecules are linked to form a much larger molecule usually called polymers. Poly( ethene) is formed when ethene and it's derivatives undergoes polymerization reaction. Therefore poly( ethene) is a polymer of ethene.
To describe the reason why there is higher melting point in poly (ethene) than ethene is that poly( ethene) consists of very long chain carbon atoms which are held together by a strong covalent bonds. There are greater intermolecular forces between the long chains compared with smaller simple molecules like ethene.
Answer:
B
Explanation:
A proper balance between cell quiescence and mitosis ensures the right tissue homeostasis. Due to regular erosion of cells in the gut lining they have to be replaced frequently. In this case there are more cell in mitosis phase than quiescent phase. To replace the cells will exact copies, the DNA in the parent cells acts as a template for the duplication of copies for the daughter cells. During duplication in mitosis, there are checkpoints that ensure the process is proceeding with precision as required to produce exact copies. In case there are errors, they are repaired before one step is proceeded by the other. In the case of irreparable damage, these cells undergo induced apoptosis.
