My Google Search Stories





This is a Chemistry Safety video I wanted to do myself and I figured I'd upload it anyways. I guess you could think of it as What NOT to do with Chemistry.


This is my good copy of Chemistry safety.

Just Because We Can, Doesn't Mean We Should?

Question 4: Should we be able to select the traits to make the perfect baby?

No. I do not think that we should be able to do this because humans would not be as unique as they are now. If babies are all perfect, the world, along with humans would be boring.

Making a Decision for Genetown.

I disagree. The intent for this research is good, it could help humans in the future by curing serious diseases and injuries. But the way that they will conduct this research does not seem appropriate. Embryos should not just be "Specimens" to study by scientists. They are future human beings and deserve to live their life. They might even make a difference in the world by being the next Steve Jobs or Bill Gates. Stem Cells Now has good intentions but I do not agree with the way they are going to research. Killing off Embryos does not belong in this town.

The Cell Cycle

The Cell Cycle is so important because it contains the 3 stages of the cell’s life, and they are the Mitosis, Cytokinesis, and the Interphase.

1) Interphase

The first of these stages is the Interphase, which is the longest stage in the cycle. It is the time when cells perform the various functions within the organism. During Interphase, the cell doubles almost everything in it’s cytoplasm. In the first phase, a cell increases in size and creates the proteins/molecules needed by the cell so it can function. The second stage of Interphase is replication, in which DNA copies, or replicates its self. During this stage, the cell copies 3 billion base pairs of DNA information that is inside the nucleus. Enzymes control this process. After the DNA is replicated, the cell still continues to grow and make materials like proteins.

2) Mitosis

Mitosis is the second stage of the Cell Cycle, and is also the shortest most of the time. Mitosis is when the contents of the Nucleus splits up. This splitting results in two “daughter” nuclei, each with the same number/kinds of Chromosomes as the normal nucleus. Sometimes mistakes are made during this process but the daughter cells are normally identical to the parent. When the nucleus prepares to divide, the DNA inside of it forms sister Chromatids of a Chromosome. Something called a Centromere then joins 4 sister Chromatids.

3) Cytokinesis

This is the final stage of the Cell Cycle. Cytokinesis separates the two nuclei into two daughter cells. Both of these sells are completely alike to the parent cell. In an Animal Cell, the cell membrane pinches together to split up the cytoplasm and it’s organelles. In a plant cell, a cell plate forms along the middle to separate the cell into two daughter cells.

I have white forelock hair (Dominant trait) from my mom’s genes. My dad doesn’t have white forelock hair. If I were to have no white forelock hair, it would be a Recessive trait.

I probably don’t have any dimples (Recessive trait) because my father does not have any. My mom does though, so I must have no dimples because of my dad. The null trait of having no dimples is to have dimples (Dominant trait), which means you have little dents around your mouth.

I have no mid-digit hair (Dominant trait), and my father doesn’t either. This means that I got those genes from him. The null trait of this is having mid-digit hair (Recessive trait).

I have a straight pinky (Recessive trait). My dad also has a straight pinky, so I got these genes from him. The opposite of having a straight pinky is a bent pinky (Dominant trait).

I have free earlobes (Dominant Trait). My mom and dad both have free earlobes, so I definitely got these genes from my parents. The opposite of my free earlobes are attached earlobes (Recessive trait), which, hence it’s name, means that the ear lobes are attached to your skin instead of just hanging.

I have a Curved thumb (Recessive Trait) because my both my mother and father can do it, so I clearly got those genes from them both. The null trait of a Curved thumb is a straight thumb (Dominant Trait), where you can’t bend it.

I have a longer first toe than my second toe, and the only person in my family that has this is my grandpa. So I must have skipped a generation and gotten some of those genes from him.

I can roll my tongue (Dominant trait). If would not be able to roll my tongue, it would be a Recessive trait.
