The biggest difference between viruses and bacteria is that viruses must have a living host - like a plant or animal - to multiply, while most bacteria can grow on non-living surfaces.Bacteria are intercellular organisms(. they live in-between cells); whereas viruses are intracellular organisms (they infiltrate the host cell and live inside the cell). They change the host cell's genetic material from its normal function to producing the virus itself.There are some useful bacteria but all viruses are harmful.Antibiotics can kill bacteria but not viruses.An example of a disease caused by bacteria is strep throat and an example of an affliction caused by a virus is the flu.

BOW 9 virtual epidemic

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 in 17 rounds  more than 120 people have died and spread it around

BOW 8 Hot Zone

what i like most about the hot zone is that it gives you so many details that you can actually picture it,also it gives me  information about diseases i have never heard about which it interest me much more. I love how the book shows what mistakes people make and what symptoms they get which is pretty scary, But after all its good because it  teaches  me how to be careful and what things can cause you disease and how it spreads.

vaccine is any preparation used as a preventive inoculation to confer immunity against a specific disease,usually employing aninnocuous form of the disease agent, as killed or weakenedbacteria or viruses, to stimulate antibody production

BOW 6

diffusion : The spread of one area to a different group by contact.
ex : the perfume diffuses around the room.

facilitated diffusion : type of passive transport that allows things to pass the membrane with the help of transport proteins.
ex : sugar has to be able to cross the plasma membrane.

active transport : movement of a chemical substance from a lower center of concentration to a higher center of concentration due to its energy
Ex : coffee filters

endocytosis :the process in which the cell takes in materials from the outside and fusing them with its plasma membrane.
ex: monocytes can eat foreign substances such as bacteria

exocytosis : cellular process in which a  intracellular vesicles in he cytoplasm fuse with the plasma membrane
Ex : hormones from the endocrine glands

osmosis : the movement of water across a permeable membrane
ex : white blood cell

PUPUSA RECIPE

Ingredients:

• 4 cups of water
• 5 cups masa harina flour
• 16 to 24 ounces of canned refried beans
• 3 cups soft white cheese

Preparation:

1. Using a large mixing bowl, slowly pour water into masa harina. Stir until dough forms a ball that can be handled.

2. In a separate bowl, pour the refried beans. Place the grated cheese into another bowl.

3. Divide dough into about 25 pieces. Roll each into a ball and flatten between the palms of your hands to about 1/2-inch thick. Put a spoonful of beans and a small handful of cheese into the center of each pupusa. Flatten again with the filling inside.

4. Fry the pupusas in a flat skillet. Cook each side 4 to 5 minutes until a pale golden brown. The outside should be firm and crisp.

Cattle, like other ruminant animals such as goats, deer, and giraffes, have billions of microbes inside their guts which help them digest their food. These are some of the many types of microbes that live in the rumens (stomachs) of cows. The large microbe is a type of protist. The creature that looks like a tadpole attached to the side of the protist is a fungal spore. The smaller, rod-shaped beasts lining the underside of the protist are bacteria.

       This bacterium is an anaerobic toluene degrader. It was isolated from a gasoline-contaminated aquifer in Michigan. This organism was isolated and studied by Joanne Chee-Sanford as part of her doctoral dissertation research. It is being displayed as our "Microbe of the Week" (during April 1996) in honor of Dr. Chee-Sanford's recent successful defense of her dissertation project

Yeast are small fungi which are incredibly important in the food and beverage industries. Yeast ferement the sugars in fruits to make wine, the sugars in grains to make beers. When grown in the presence of oxygen, yeast give off the gas carbon dioxide which makes bread rise. Yeast can grow with oxygen, (aerobically) or without oxygen (anaerobically.) Because it can grow either aerobically or anaerobically, it is known as a "facultative aerobe."

         In August of 1996 NASA scientists reported finding what look like fossils of microbes inside a meteorite (called ALH84001) thought to be from Mars. They believe the 4.5 billion year old rock was once a part of Mars. It was blasted from Mars by a huge meteor impact 16 million years ago. It fell to Earth in Antarctica 13 thousand years ago. A piece of the meteorite was discovered on an ice field in Antarctica by scientists in 1984. Inside of the meteorite, along cracks and fissures within the rock, scientists found mineral structures such as the one shown here. Some scientists believe this may be a fossil of an ancient Martian microbe, similar to Earthly bacteria. Other scientists are skeptical, and believe that these deposits are the result of inorganic chemical processes that by chance happen to resemble terrestrial monerans. The NASA scientists have also found traces of chemicals within the cracks in the meteorite that they believe came from living organisms. These polycyclic aromatic hydrocarbons (PAHs) and carbonate globules may be products of microbial metabolisms. Visually, this structure certainly does resemble rod-shaped bacteria found on Earth. It is, however, quite small compared to terrestrial monerans; it's size is closer to that of large viruses than to the size of most bacteria. Most scientists doubt that life currently exists on Mars. However, it is very likely that Mars was much wetter early in the history of that planet, and water seems to be a critical ingredient for the formation and continuation of living organisms on Earth. Further studies, including two NASA space missions due to be launched toward Mars in late 1996, may shed additional light on the question of whether there is life elsewhere in the universe.

      This is the spiral-shaped chloroplast of the algae, Spirogyra. This chloroplast is green when viewed with traditional light microscopy. Here it is seen as red, since the chloroplast was fluorescing red.
