Blog #16-LAST BLOG Reflect on your semester and year in biology What were your successes? What were your failures? What did you learn that you will never forget?

In the second semester of this year in Biology in Ms. Malonek's class, I had some success along with some failures. First of all, one of my success would be working hard does help in the long run because if I do all my homework when it was given, I don't have to rush to finish it; thus, avoiding that I have to do sloppy work while rushing and not getting a better grade on it when I can. Additionally, good work does come with a good grade in return which will make my parents and me very happy!

Another success would be that it was really informative to learn about difference specimen's anatomy, making me compare and contrast the human's body anatomy and there is such a great difference. I used to think that  all animals had the same organs such as lungs, kidneys, etc. but that was where I was wrong and know my mistakes now.

However, I had some failures along the way and one of them is to open my ears and listen to the teachers with depth. I don't know why but when I thought the anatomy quiz was the worm and the grasshopper, I thought the anatomy quiz was going to be about the worm and the clam, instead. It was like I didn't open my ears to listen. WHAT A FAILURE! I studied for the wrong material for tomorrow's quiz!

Even though sometimes I almost cut the specimen at the wrong end, I didn't because good thing I had a partner. Therefore, I think dissecting specimen helped me learn a lot because there was actually a visual for me to learn and to actually know how each organ or thing looks like which made it easier for me to learn the material. I would always remember that preserves would make a rat look yellow and how squid can be made to yummy calamari. I would always remember "survivial of the fittest" because it is tough when people fight for candy. They were vicious people!! and they always grabbed the candy easier because they were big and strong.

Blog #15 Compare two of the organisms that we have dissected Discuss at least 2 similarities and 3 differences

I would compare the two organisms: frog and squid. These two organisms have more differences than similarities.

The first similarity would be that these two specimen both have two eyes to see. The habitat is another similarity because they live in underwater where they have a membrane for their eye. They both have closed circulatory system, external reproduction, and a complex nervous system.

There are quite some differences between the frog and the squid. The frog has a vertebrate while the squid has an invertebrate. The frog also contains kidneys, a total of three chambered hearts, lungs, and a total of four limbs. The frog, however, can live in the water but it can also live in land. The frog also uses its hind legs to jump while a squid can't even jump. Now we can also compare the color of these two specimen. It is obvious that one animal is green and has black dots; a frog also can feel slimy while a squid's color is gray and soft and slippery.

The most obvious thing an animal has is a "pen" for the bone which is what a squid has, also for squirting ink just like an octopus. The octopus, however, has many limbs in which you cannot even tell how much there are because they may vary for one squid to a different squid. The squid mainly lives underwater swimming all day long. Therefore, a squid can be eaten but usually frogs are not eaten by humans even though it is considered as seafood.

Blog 14 Which specimen that we have dissected so far seems most like humans? Why?

The specimen that we dissected so far that seems most like humans are fish out of the other specimen which were grasshopper, squid, worm and clam so far. 

One reason that humans do relate to a fish is because of all the organs they have compared to us. A fish is a similar kind of model to humans. For example, fish has kidneys, a heart, a stomach, etc whereas a worm doesn't even have a kidney and some other parts the human body has.

Both has two eyes, also ears but for fish the ears are inside their head so they don't hear that well unlike humans who hear to listen to music, hear to listen to the teacher's lectures in class, or even hear the beauty of each person's voice. The different thing about fish and humans is that they don't have similar habitats, but distinctive habitats because fish live underwater while humans live on dry land.

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

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.
