3. describe the two types of reproduction seen in living things.

The two form of reproduction seen in living organisms are:

-asexual reproduction

-sexual reproduction

Asexual reproduction are an organism can produce without  the involvement with another organism. Asexual reproduction are not limited to a single-celled organisms. Also cloning of a single organism is another form of asexual reproduction. Some species that are asexual are jellyfish,sea anemones, and corals.

Sexual reproduction requires two specialized organisms called gametes which one half of the organism have half of the number of chromosomes and of normal cells and the other organism have the other have together this is called meiosis. Meiosis typically happens when a male organism fertilize a female of the same species to create a fertilized zygote. This produces offspring organisms whose have genetic characteristic from the two parental organisms.  

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
