There are two types of reproduction, asexual, and sexual reproduction. Most organisms go through either one of these types of reproduction, depending on their species types. For example, humans go through the process of sexual reproduction. Sexual reproduction, is basically giving birth to off spring that have inherited traits from each parent. Their eye color, skin color, and hair color are all traits that can be passed down from each parent. This is exactly why you have your looks from a mixture of your parent. 
   Asexual reproduction, however, is completely different. Taka a sponge for example, a sponge can asexually reproduce, which means they have the ability to give birth to an offspring that looks completely identical to itself. Not all creatures are able to asexually reproduce, and only a few can. The main difference between these types of reproduction, is mainly just what the offspring turns out to be. If the offspring looks exactly like the parent itself, then the chances are likely, they asexually reproduced, but if the child has features from both parents, then you can tell they sexually reproduced. 

Several days ago, we were subjected to dissect a frog. We could tell the differences between the genders, as we slowly cut into it. The first step, is to extract the skin layers on the top, then we were to open the skin up, like a window opening. Once we did that, we could see all the organs, and such, located in the different parts of the body. The obvious parts were seen, but some were deep within the frog, so we have to delve deeper inside to sought them out. The frog dissection was very useful, and we collected much information from it. We learned the different body parts, and there location, as well as their functions. Knowing this information might have some use to someone who will be giving operations to someone else.
