Slate starts out as shale under the surface of the Earth before its metamorphosis. It is typically gray in color and splits along long flat planes. It is also does not allow water or other liquids to pass through it. Slate is most often used as a roofing material, decorative gardening stone and a base for snooker tables. In the Victorian era, it was commonly used as a writing board.
Marble is another one of the metamorphic rocks and is a metamorphosed limestone. It has a hard crystalline rock appearance and was the stone of choice in ancient Greece. In fact, more than 22,000 tonnes of marble were used to build the ancient Greek Parthenon and marble remains a popular building and sculpture material today. It can also be ground down to make cleaning products or soaps.
Schist is another metamorphic rock that is formed from either mud or shale. However, it is formed at a much higher temperature than slate is. Schist is a fairly weak rock so it does not make for a good building material. It is used for paving and occasionally sculpture.
<span>Viruses are not usually classified into conventional taxonomic groups but are usually grouped according to such properties as size, the type of nucleic acid they contain, the structure of the capsid and the number of protein subunits in it, host species, and immunological characteristics. This is because they don't fit well in any existing classification currently.</span>
Answer: a. Heritability research is able to identify genes for particular behavior patterns.
Explanation:
Heritability is the ability of a trait to move from one generation to another. Heritability, sum of phenotypic (observable) variability that is due to human genetic variations in a population.
Heritability, in a general sense, is the ratio of variability for a trait or character in a population due to variations between genotypes and the overall phenotypic variation.
Hence, as genes identification is are the basis of heritability research, option "a" is incorrect.

hope u got it right
When blood ph is above normal range, it is a condition called, alkolosis. When blood ph is below the normal range, it is a condition called acidosis.
I hope this helps :)
