One of the most famous holiday legends who is known as St. Nick, Nicholas Claus, or Father Christmas, however, more popularly known as Santa Claus. Scientists say that he's fake. Children say that he's real. Is it true? We will never know. 
                However, according to an article and a rebuttal article, it is concluded that he is dead. They've been talking and asking many questions about him, like how does his reindeer fly, or how does he travel 650 miles per minute. Some say that his reindeer flies because of magic acorns, while others say that it's just the way things are. According to their calculations, they say that Santa gains more than 4,000 pounds because of the cookies and milk he eats. I say that he is fake, because really, it isn't humanly possible for someone to gain that much weight in a night. Whether they're Santa Claus or not. Also, there is no such things as "magic acorns" that make reindeer fly. In fact, reindeer don't fly at all!  They just jump really high. 
              In conclusion, I believe that Santa Claus isn't real whether he brings presents or not. Sometimes, even little children knows he's not real, but are likely to fake it to amuse their parents. I know that not everyone will agree with me but I would be better off saying what I believe in instead of what I disagree with.
        The DNA is the main thing that copies our genetics from our parents. Their  shape is like a twisted ladder, also known as a double helix. They have four nucleotides: adenine, guanine, thymine, and cytosine.
         DNA structures are  connected by little small bars of deoxyribose sugar. They  are carried by pairs of nucleotides. Each pair will never be separated, because each pair is the same as another. Adenine and thymine will always be a pair, and so will guanine and cytosine. Their structure is a double helix. I don't know why, but I do have a theory. My theory is the reason why it is a double helix is because it helps transfer the deoxyribose sugar faster. The spirals of the helix makes the it more flexible, fluid, and smooth, making the sugar go up or down easily. Think of a twisty slide. If the slide was straight, then it wouldn't be as smooth as it was before. The twist of the slide helps by making it smoother, because of the flexibility.
          The structure of DNA took many years to figure out. A woman scientist, called Rosalind Franklin, took many years and days to find the information. She took X-rays, and she drew what she discovered in her little notebook. DNA is what makes us different, and what gives us our similarities. So to conclude it, the structure of DNA is a double helix. 
         There are many types of cells everywhere. Plant cells, animal cells, nerve cells, you name it. They also look different too. I don't think that any of different species of cells look the same. They all have their unique looks and ways of functioning.
       Plant cells have a cell wall, something that the animal cells don't have. They help secure the plant cell to protect it. They also have something called a chloroplast. The chloroplast has a green colored pigment, which is the reason why plants have that green color. The chloroplast captures energy from the sun and turns into food to feed the plant, and this process is called photosynthesis.
        Animal cells are a bit different however. Animal cells don't have a chloroplast and a cell wall. They have to consume their own food and break it down to release it. The cell part that does that is called the mitochondrion. It's the powerhouse of the cell. 
         Both of these cells have things in common too. They're both eukaryotic because they have nuclei in them. The nucleus tells each cell what to do and is the "brain" of the cell. In ways, they both have their differences and similarities. Sort of like people. However, in reality, they're just cells doing their job.
