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.
Any molecules that exist as strings of the same or similar subunits<span> are called polymers;</span>starch<span>, proteins, and nucleic acids are all polymers, as are many artificial materials, such as plastics. Its a relatively easy way to build big molecules.</span>
In that situation the risk of cord compression during the child birth. Serious umbilical cord problems can result in brain damage or the death of baby.
Umbilical cord occurs when the baby weight on the placenta or the vaginal walls put pressure on the cord during pregnancy labor or delivery. Cord compression during pregnancy is common problem. Sing of umbilical cord compression may include less activity form the bay observed as a decrease in movement or an irregular heart beats.
Umbilical cord compression is a medical term used to describe a condition in which a baby's umbilical cord becomes flattened by pressure of the baby.

Because it is both dead and alive !!
When outside the host , it is inactive or dead , but as it goes inside the host , it starts multiplying by hijacking the genetic machinery of the host cell !!
this property makes the virus unique of all !!
