1. The scientists before 2001 were trying to determinethe sequences of the 3 billion chemical base pairs that make up human DNA and identify the about 20,000- 25,000 genes in human DNA.After 2001 they are still analyzing the data they got.The potential benefits to science, medicine, and human life are that they can make us more aware of our surroundings. Doctors could know more about the affects of medicine to help our human life.The public funded universities more people could know more about their project than the private-funded research companies.
2. Not all evidence is because the DNA match isn't satisfied to the burden of being proven guilty.http://www.llrx.com/features/dnareliability.htm. t's harmful beacuse once you upload your personal information publicly anyone can access it.http://www.dnareunion.org/term.php?&__atoken=__NONE__.
3The sex-linked traits to male chromosomes the male is dominant.I found interesting are XX and XXY because even though there's equal female. hey should either have no choice to have children or adopt a kid.
4. The Human Epigenome Project and they are focusing to identify, catalogue and interpret genome-wide DNA methylation patterns of all human genes in all major tissues.They hope to significantly advance our ability to understand and diagnose human disease. http://www.epigenome.org/index.php?page=project

Cell Evidence of Kingdoms
There are many kingdoms and many organisms that fall under. The kingdoms are Archaebacteria, Eubacteria, Animalia, Plantae, Fungi and Protista. Unicellular organisms are in the Archaebacteria, Eubacteria kingdoms. Multicellular organisms are in the Animalia, Plantae and Fungi kingdoms. Protista is the only kingdom that has both unicellular and multicellular organisms.Plantae, Fungi and Protista's cells all reproduce sexually and asexually. Archaebacteria and Eubacteria's cells both reproduce asexually. Animalia's only reproduces sexually.
All of the kingdoms have a unique shape of their cells. Archaebacteria, Protista and Eubacteria are autotrophic and heterotrophic. Animalia and Fungi are both heterotrophic. Plantae is only autotrophic. Animalia, Plantae, Fungi and Protista are eukaryotic. Archaebacteria and Eubacteria are prokaryotic. Archaebacteria organisms live in salty environments.Some Eubacteria have a second membrane outside the cell membrane.In Animalia, 5% of animals are called vertebrates. Plantae produces oxygen. In Fungi, mushrooms can reproduce sexually and asexually. Protistas are free-living protozoans. Each kingdom has something special about them.

Cells
Cells are the basic functional units in organisms. There are multicellular organisms, organisms who contain many cells. There are also unicellular organisms, organisms contained only one cell. An example of a multicellular organism is a human. An example of a unicellular organism is Amoeba.
There are two types of cells: prokaryotic and eukaryotic. Prokaryotic cells are more smaller than eukaryotic cells and lacking of a nucleus and other organelles of eukaryotes. There are two types of prokaryotes that share similar structures: bacteria and archaea. Eukaryotic cells are way larger and complex than prokaryotic cells. A big difference between them is that eukaryotic cells contain membrane-bound compartments. Examples of complex organisms that are eukaryotes are animals, plants and fungi. The cell divison is different from prokaryotes since prokaryotes don't contain a nucleus. Cells are the building blocks of life.

Osmosis
Osmosis is the movement of solvent molecules through a selectively permeable membrane into regions of high concentration to regions of low concentration. Diffusion is the spread of particles through random motion from regions of high concentration to regions to low concentration. The difference between them is that osmsosis is the diffusion of water only, throught passive transport and diffusion is the transport of varies substances by the means of passive or active transport. In diffusion and osmosis any passive transport can happen without energy since they don't need ATP. A concentration gradient is when there's an uneven distribution of a substance across a border. An exmaple: If we picture each individual molecule as a little blue dot and there's a thousand of them. On one side there is 850 little blue dots and the other side is 150, the sides aren't even. Solute & Solvent have to do with Osmosis and Diffusion because osmosis is the diffusion of solvent through a permeable membrane. Water is not always a solvent because not all things dissolve in water.
