Which process is a form of mechanical weathering apex

Physical weathering, also known as disaggregation or mechanical weathering, refers to the category of procedures, which makes the disintegration of rocks in the absence of chemical modification. In general, the mechanical weathering takes place due to the build-up of pressure within the rocks.  

However, the rocks can also get worn away by a procedure known as abrasion. Abrasion refers to the disintegration of rocks due to friction.  

This is true, asexual reproduction involes the exact copying of a parent to its offspring.  In sexual reproduction, two parent's DNA is intermixed, thus giving new DNA.  Since there is only one parent in asexual reproduction, there is no chance of variability.  The only time the DNA may be different is during a mutation, which is not caused during the reproduction.

The answer is true.
