Transcript of A Look Into Another World

Hello and welcome to the lab. If you take a look through the microscope I think you'll learn a lot.
Bacteria is found in every accessible environment. They also lack a membrane.
Bacteria reproduce mostly through a process called binary fission.
Do not disturb!
You can find out how much bacteria will grow through a "simple" formula
G=t over n=t over 3.3logb/B
The B is the number of germs at the start of the observation. And b is the number present after the time period. And t and n are the of generations.
Over crowed cities also serve as breeding grounds for the infectious agents.
Meiosis is a special form of germ cell division.
Meiosis Prophase II
Now lets move onto a different type of infectious agent.
The Fungi
Fungi exist as yeast or molds
I'm What!
A mold is a branching structure formed by several cells lying together
Am I branching correctly?
So am I am I!?
We will only focus on the molds though and no it is not the bread yeast
Now we will move onto how these germs are spread
Families with infants and preschoolers can let a disease spread more easily.
Certain undiserable conditions could lead to droplets that contain the virus infecting others.
They're going to infect everything!
Insects are another and well more known way for a disease to spread.
A milder winters have increased forestive insects and higher temperatures have increased their reproductive rates.
Food and water transmission also plays an important role in infecting humans.
Come on don't make me eat it
Mwahaha I shall infect you
60-80 percent of human infections originate from animals
Time to infect
Now lets move onto a different topic how does the germ survive
?
Now you may think they have to live inside other cells, to survive, but they can survive inside the body outside of other sides
Fungi can live on dead or rotting animal or plant matter
I used a stick man because a real dead body is just disgusting. No stick men were harmed in the making of this prezi
Organisms can live harmlessly in their host, but with diseases that is not the case
This bacteria does not live harmlessly in its host
One germ creates something called sputum which resides in the nose and throat.
P.S. Sputum is a mixture of mucus and siliva
This is where sputum resides
And that concludes our journey. I hope you learned a lot, and I think we covered the basics of infection and survival.Hope you visit the lab again tata.
