Blog #13 What was most interesting about this week's dissections?

The most interesting in this week's dissections was that some animals actually don't have hearts, eyeballs, or certain organs. In my opinion, I think humans usually need most parts of their body. For example, we need eyes to see things in case we might bump into someone that we don't want to. We need ears to hear things such as listening to music or even listening to the teachers yell at us when we don't want that to happen.

We use our hands to touch, to feel what is surronding us or to feel how things feel like such as the wodden floor, the bumpy floor, or even the rocky floor. There are also the nose we use to smell foods or even stinky perfume. For example, even though we to smell something good, we don't want to smell stuff that taste bad. For example, the big trash truck is right next to my friend and me so she sprays perfume everyone around us to make us smell the perfume instead of the nasty, stinky trash. Also, when we smell our parents making our dinner, yummy! it smells so good that we ask what is for dinner and etc...

What else was fascinating was that I thought we were only doing a frog dissection but I was wrong because we did all kinds of dissections-the clam, worm crayfish, and etc. It was interesting how we got to know how these animals/species move and how it looks inside their bodies because their bodies looks so different from my body and the other type of animals' bodies. The shape, color, or even texture is so different that even there are organs they don't have! Interesting isn't it?!

I think there will be wayyyyy more fascinating stuff in next week's dissection since the dissection part of the chapter is not finish yet! Frogs~

Blog#12 What surprised you from the worm's dissection?

Blog#12 What surprised you from the worm's dissection?

What surprised me in the worm dissection was not only one thing but plenty of things.

At the first place, I didn't there were some worms that were as long as the ones we dissected in class that were at the same time really skinny. It was longer than my whole hand, but also skinner than one of my fingers.

The second thing I was surprised was that it was so simple to dissect a worm; we just needed to use a simple blade, and there the skin opened and we saw the organs inside the worm while putting pins to keep the worm in place.

Another thing was that inside the worm, there was huge amounts of dirt. From top to bottom was full of dirt and it seemed like nothing else. Well, it was from the clitellum to like the annus part of the worm. Sometimes I wonder if all worms eat are DIRT, DIRT, DIRT, and nothing else to fill up their stomach.

I was also surprised that worms have FIVE HEARTS! Because they have five hearts, I wonder if they have five lives like a cat supposedly have nine lives. Well, it must be false that the worm has five lives because the worm should have survived after we dissected it and since it didn't that might be a safer thing because I know worms won't run around the classroom or school.

Blog #11 Get a picture of alternation of generations put it in your blog and explain how it relates to plants



This is the alternation of generations- of ferns obviously.

The alternation of generations refers to the occurrence in the plant life cycle of both a multicellular diploid organism and a multicellular haploid organism. For example, ferns can be part of an alternation of generations because this plant life cycle is either or both the diploid plant or the haploid plant. The process will be from meiosis to mitosis as shown in the digram but in between, fetilization will occur or take place.

 

First of all, the large leafy plant is the diploid organism; these diploid have to undergo a process which is meiosis to create haploid cells, which is seen- the other plant. Therefore, these cells will not adapt quickly to form diploid cells that fast. Instead, they are shedded like spores and germinate into small haploid organisms. Since the diploid cells create spores, it is called as the sporophyte generation of their life cycle. Over some time of maturity, the haploid organism will create haploid gametes or could be called as the gametophyte generation of their life cycle. The male gametes will then be released and swim to the female egg; then it will be completed as the full or completed life cycle.

Anatomization is another word for dissection; thus, dissection is the process of disassebling and observing something to determine its internal structure and it helps as an aid to discerning the functions and relationships of its components. Dissection is an important part of a biology curriculum because it is a sort of model for humans to use it on. For example, mice or rats are used for experiments to determine if something could work on the rats in order to work for humans.

A rat could be tested on something before used on humans. Such as a type of medicine or surgery to make sure it is used safety to be performed on humans. Even though dissection may look unpleasant and nasty, that is one way to experiment what does and doesn't work for humans.

In the short story- Flowers for Algeron, it is first tested on the rat Algernon to make sure if it works on a human. The surgery was to be make a person/animal smarter by doing the surgery on their brain. After experimenting it, it really worked on the rat; therefore, they started surgery on the person to make him smarter. A few weeks later, he was really really smart but then the rat had some problems. Later on, the rat died! To see what happened during the experiment and not continue with this type of surgery, the scientists had to cut the rat open to see why it died and didn't stay alive.

Some other animals such as frog are dissected at school in the course Biology to show students how it is inside a body like the tissue or the stomach, etc. Maybe some other animals can be use in dissection can be birds or even worms. However, I also don't think birds would work because their habitat is different from ours and humans don't have wings.
