One major difference between asexual and sexual reproduction is that a) sexual reproduction makes clones. b) asexual reproduction creates clones. c) sexual reproduction has one cell division. d) asexual reproduction has two cell divisions.

B. asexual reproduction creates clones.

Asexual reproduction involves the reproduction of offspring from a single parent. It occurs in simple organisms. The offspring produce in this type of reproduction is identical to the parent as same genetic information is passed from the parent to the offspring. No segregation of gene takes place in this process. In sexual reproduction two parent are involved. This involves gamete formation. The segregation of genetic information takes place and randomly genes are transferred from parents to offsprings. This results in occurrence of genetic variations in the offspring. The offsprings produce by this reproduction are not genetically identical to their parents.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
