Literature: 5 fables

For the first fable called "The Wolf in Sheep's Clothing", the story was about a wolf who disguised herself as a sheep with a sheep's skin. At the end of the story, the wolf eventually got a sheep and ate it. I think that the fable's maxim of this story is that appearances are unreliable. This means that even if you look tough and scary it doesn't mean that you are one, in fact, you could be really nice and smart. For the second fable called "The Four Oxen and the Lion", the story is about a lion trying to scare and eat the four oxen but the lion couldn't because the four oxen came together and defended one another but then the four oxen fell and each went separate ways, so the lion attacked the four oxen and had an appetizing lunch. I think the fable's maxim of this story is that if we are together, were indestructible, but if we are apart, we are nothing. The third fable called "The Fisher and the Little Fish", it is about the little fish begging for the fisher to put him back in the river and make him grow so that the fisher could have a bigger meal but then the fisher refused. In this story, I think the fable's maxim is that little things are worth more than a great thing in view. This means that little things are more valuable than bigger thins. This fable relates to "less is more." The fourth fable is called "The Crow and the Pitcher", this story is about a crow who was really thirst found a pitcher with a little bit of water in it. The crow couldn't reach the water inside the pitcher so he took little pebbles and put it in the pitcher, soon after, the water was high enough for the crow to take a sip. I think that the fable's maxim is that doing thinks little by little will do the trick. This means that doing things little by little can make you reach your goal. The last fable is called "The Fox and the Goat"; it is about a goat who found a fox in a well. The fox told the goat to come join him in the well so the goat jumped in the well but then suddenly the fox grabbed his horns and got to out the well while the goat was stuck in the well and was left there. I think the fable's maxim is to think before you act, meaning that before you do something foolish, think about it before you do it.

"Wooden Bowl"

This story was very interesting to and moving to me. In this story, there lived a grandfather who lives with his son, daughter-in-law, and his four-year-old grandson. He is very weak and old, that's why he would always have difficulty eating his food every time the family eats in the family table. The son and the daughter-in-law were annoyed by it because they would always have to clean his mess up. So, what they did was they but a table at the corner of the room and made him eat there alone. When I read this part I was really sad because his tears came down his eyes because he was eating alone in the corner. So, I think that this relates to empathy because the grandson had empathy to his grandfather and realized that he didn't like eating alone and was upset. Also, the son and the daughter-in-law realized that what they did was wrong and led the grandfather in the family table again which was really touching to me.

Ask a Geneticist

There was a lot of interesting things I learned about in the two website. First, I read about Flo Pauli's answer to the question, "I realized that humans have 46 chromosomes and chimps 48, but do we (Homo sapiens) have more genes or fewer genes than the chimps?" When reading this question to myself, I thought that chimps have fewer genes than us, I don't know why I thought that, but I think that humans are healthier than chimps. Anyways, from this article I learned that 98.8% of chimps and humans are the same and only 1.2% different. Also, I learned that even though chimps and human have different numbers of chromosomes, it doesn't mean their different, in fact, us and the chimps would probably have the same number of genes. The other thing I learned from this article was that there is no relationship between the number of chromosomes and genes. One example is that humans have 46 chromosomes, while goldfish have 94. One of the fact that I learned today that was so interesting to me was the part when 2 of the chimps chromosomes was in one of the humans chromosomes or which you may call it vice versa . There was also another fact that I read about that amazed me. It was in the reading about how humans and chimps used so start with the same number of chromosomes but then 5 million years ago, the two organisms drifted apart, their genomes changes, some sections were lost, gained, and others were copied.

In this article, Dr.Bronwyn MacInnis answered a question that was, "why is the [human] genome split into separated chromosomes rather than being one long strand and what determines[ed] which genes went to which chromosomes?" When reading this question to myself, I was also curious why we can't just have one long strand of chromosomes and not 46 split chromosomes. In this website, I learn that it is a mystery on how we have 46 chromosomes also I learned that we all have copies of every chromosome except for males. This article doesn't really interests me because I have mostly learned this in science. For example, I already know that both mom and dad give half of their chromosomes which at the end will have two copies of each chromosome just like the mom and dad but our DNA is mixed. In the first article I said that 2 of the chimp’s chromosomes were in one of the humans chromosomes. Well, in this article it said that some chromosomes break off and where ticked to other chromosomes. Now, in the last 6-8 million years, 2 of the chromosomes fused together and made 2 chimp chromosomes. Some of the things I didn't know about were that certain type of fern or another word for it is "Ophioglossum reticulatum" has 1,260 and still we are more complex than a fern.

Basic Genetics (Heredity & Traits)

Heredit
Heredity is the passing of traits from the parents to their child. I learned that there are two sets of twenty-three chromosomes. One of the sets is is the sperm cell from the father and the mother set is called the egg cell. When this two sets join, they form a cell called "zygote" which have foury-six chromosomes. I also learned that each child gets half of the parents chromosomes and each child each inherits a unique set of chromosomes and the one rule of heredity is that the child must receive one of each chromosomes. Every child will have a resemble of the mother and the father.

Trait
A trail is what makes us different to one another outside of our body, but, in the inside we are all alike because 99.9% identical DNA. There are different types of traits like our physical traits, behavioral traits, and predispostion to a medical condition. Genes plays a role of defining our traits, but, the non-genetics or environmental can sometimes change our traits. One of the examples of one of the traits is called physical trait which is when our genes tells us our real hair color but for the non-genetics, people change their hair color.

science

One thing I learned in the owl pellet is that more than two small animals like rodents can be in the pellet. I also learned that there must be plenty of moles and rodents in the area were the pellet was found. I can tell because what i said before, there are at least more than two rodents and or moles. I learend that owls eat the prey hole but then a week or two after, the owl throw up the left over fur and bones and that is how a pellet is made. I also learned that the pellet is not manure but it is the left overs that owl cannot digest.

current event 2

"Are Wolves the Ponghorn's Bestfriend?"

The Western States are debating whether the gray wolf should be removed from protection under Endangered Species Act. People had says that fewer wolves mean more coyotes and more coyotes means fewer pronghorn fawns. But, in their study, healthy wolfs keps the coyotes in number. Over a three-year period, researchers had more that 100 fawns without the wolfs in the Grand Teton National Park. In their resault, only 10 percent of fawns survieved in area with wolfs and had more coyotes. In the area without wolfs, more fawns survived (34 percent). The wolfs kill or cause the coyotes to shift into another area to reduce the number of coyotes.

I feel like wolves shouldn't be isolated from all the other animals because they are also a part of nature. How they live with other animals should be kept as it is. A species of animals may be alrger than another species. That's just how it is going to be. But I sometimes feel animals shouldn't be over powered by other animals. It's better if there are equal amounts of each species everywhere, but I know that that will not happen because animals have to survive. Aniamls have their own special way of living and humans shouldn't interfere with the way nature works.

Current Event 1

The article I just read is called "Drunk Fruit Flies Provide Alcoholism Cure". The researchers from North Carolina and Boston universities identified networks of genes, also found in human that play a role in alcohol drinking behavior. To find this discovery, the researchers timed the fruit flies on how long it took them to lose their postural control after the exposure to alcohol. This changes the expression of all fruit flies at the same time and the genes were recorded. By doing this, they knew the specific genes that adapt relating to alcohol exposure. This helps them contribute to alcohol drinking habits in human.
This article is really interesting. I learned that this can help the balance between nature and nurture. Also I learned that this helps the scientist know why we behave the way we do, whats better and worse, and what makes us mad. This is the key role in alcohol drinking behavior. I learned that discovery have negative side affects like liver damage.
