Olenka [21]3 years ago

As we know there is a certain force called the frictional force that is required in order to resist the movement of a certain object. This frictional force occurs whenever two objects are rubbed against each other. The frictional force generated is converted to heat energy in due time making the surface hot.

Explain the rock cycle by describing how an igneous rock can become a sedimentary rock, then a metamorphic rock, and then an ign
Paraphin [41]
An igneous rock can be formed from cooled magma. The igneous rock can become sedimentary if it is broken down by wind or water. The sedimentary rock can become metamorphic if it becomes buried in the earth, where pressure and heat would turn it into a metamorphic rock. The metamorphic rock can then become an igneous rock by melting underground and turning into magma, flowing out of a volcano, and cooling.

How does loseing laforin give you epilepsy ( please use lots of detail in the answer)
Deffense [45]
<span>Lafora disease is the most severe teenage-onset progressive epilepsy, a unique form of glycogenosis with perikaryal accumulation of an abnormal form of glycogen, and a neurodegenerative disorder exhibiting an unusual generalized organellar disintegration. The disease is caused by mutations of the EPM2A gene, which encodes two isoforms of the laforin protein tyrosine phosphatase, having alternate carboxyl termini, one localized in the cytoplasm (endoplasmic reticulum) and the other in the nucleus. To date, all documented disease mutations, including the knockout mouse model deletion, have been in the segment of the protein common to both isoforms. It is therefore not known whether dysfunction of the cytoplasmic, nuclear, or both isoforms leads to the disease. In the present work, we identify six novel mutations, one of which, c.950insT (Q319fs), is the first mutation specific to the cytoplasmic laforin isoform, implicating this isoform in disease pathogenesis. To confirm this mutation's deleterious effect on laforin, we studied the resultant protein's subcellular localization and function and show a drastic reduction in its phosphatase activity, despite maintenance of its location at the endoplasmic reticulum.
