The material, which does not melt at any temperature is WOOD.
Wood is made up of many substances including lignin, water, cellulose and other organic materials. When wood is heated, it normally oxidizes in the presence of oxygen before it has the chance to melt. The physical structure of the wood is typically destroyed during this process and the original material can not be obtain again.This irreversible breakdown of wood makes it impossible for wood to melt. <span />

What phrase from the Preamble justifies a law like the Affordable Care Act?

Therefore the Affordable Care Act, which aims to increase access to healthcare to all Americans is adhering to this phrase.</span>

The meselson-stahl experiment demonstrated that DNA replication is semi conservative in the figure semi conservative replication
Vlad1618 [11]

Answer:

The correct answer will be option-D.

Explanation:

The semi-conservative mode of replication is the common method of replication used by mostly organisms on earth which were demonstrated by the Meselson and Stahl in 1958.

They used the isotopes of the nitrogen which contains extra neuron which makes the nitrogen-heavy and cultured them in bacteria

The experiment concluded that newly replicated double stranded DNA contains one newly synthesized DNA strand which is complementary to another parental strand. Thus new DNA molecule has one parental strand while other newly synthesized strand.

This is best illustrated by the option-D in the figure and therefore is the correct answer.
