The filiform papillae are pointed and threadlike in appearance. They are present on the surface of the tongue. The filiform papillae have tactile receptors and lack the taste buds.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
