BOW 9 Virtual Epidemic (Blog of the Week)





A combination of high H>C levels , high C>S levels (the contagiousness of the disease) and high S>D levels ( the deadliness of the diseases) will cause the worst deadly epidemic.

My Data: (As you can see after about 15 rounds everyone died after the carrier of the disease gave the disease to someone else.)

BOW 8 Hot Zone (Blog of the Week)

The one thing that fascinated me from reading the Hot Zone is when Monet got infected with the Marburg virus because the Marburg virus is really deadly and has many symptoms such as droopy eyelids, bright red eyelids, black vomit, hemorrhage, and blood clotting up. I was surprised that Monet died from the disease.

Cell Movement BOW (blog of week 6)

Diffusion- the spread of particles through random motion from regions of higher concentration to areas of lower concentration


Reference: http://en.wikipedia.org/wiki/Diffusion 

Facilitated diffusion- molecules that cannot diffuse across the cell membrane's lipid bilayer on their own move through protein channels instead.

Active transport- when cells move materials in the opposite direction against a concentration difference

Endocytosis- the process of taking material into the cell by means of infoldings, or pockets, of the cell membrane

The three different cells BOW 5 (Blog of the Week 5)



Neuron cells



A neuron is known as an electircally charged cell that processes and transmits information by electrical and chemical signaling. Neurons connect to each other to form networks. Neurons are the core components of the nervouse system, which includes the brain and the spinal cord. Neurons are a type of cell that are found in the bodies of most animals.

Myocyte



A myocyte is the type of cell found in muscles that arise from myoblasts. Each myocyte contain long chains of sarcomeres, which are the contractile units of the cell. The forms of myocytes are the skeletal, cardiac, and the smooth muscle ells. The cardiac myocytes generates the electrical impulses that control the heart rate.

Epithelial tissues



The epithelial tissues line the surfaces and cavities of structures throughout the body, and may also form glands. The functions of the epithelial cells include secretion, protection, selective absorption, regulation and exchange of chemicals between underlying tissues, and detection of sensation.The epithelial cells can also be organized into clusters of cells that function as endocrine and exorine glands.
