Describe the major advantages and disadvantages of asexual and sexual reproduction.

Asexual reproduction is usually faster and uses less energy than sexual reproduction. But asexual reproduction produces no differences in DNA among offspring, and creates competition for resources.  Sexual reproduction produces differences in the DNA of offspring, and competition for resources is not as high. But sexual reproduction can require a lot more time and energy.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
