Answer: d. Extracellular matrix was discovered more than 20 years ago.
Explanation:
According to biological sciences, the extracellular matrix is a matrix that consists of three dimensional network of extracellular macromolecules such as enzymes, collagen and glycoproteins which provide structural and biological support for surrounding cells as well.
It is found that it is discovered over 20 years ago in the matrix formed in the mouse EHS sarcoma. Therefore, correct answer is (d).

First is the Nebula, a cloud of gas and dust in space where stars are born.
Second is a Star, Luminous globe of gas producing its own heat and light through nuclear reactions.
Third is Red Giant, a large bright star with cool surface, it is formed during the later stage of evolution of a star like our sun.

<span>the answer is :
permanent magnets
</span>A permanent magnet<span> is an object made from a material that is </span>magnetized<span> and creates its own persistent magnetic field. An everyday example is a </span>refrigerator magnet<span> used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called </span>ferromagnetic<span> (or </span>ferrimagnetic<span>). These include </span>iron<span>, </span>nickel<span>, </span>cobalt<span>, some alloys of </span>rare-earth metals<span>, and some naturally occurring minerals such as </span>lodestone<span>. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of </span>magnetism<span>.</span>
