Bacteriophage Influenza Virus


Influenza Virus Replicating


Spherical shaped bacteria

Cocci (sore throat)

Rod shaped bacteria

Bacilli (thypoid)

Bent bacteria

Vibrio (cholera)

Spiral shaped bacteria

Spirillum (syphilis)


Culturing Bacteria1. Obtain a petri dish containing sterile nutrient agar.

Keep the lid on whenever possible.2. Sterilise a wire loop by passing it quickly through a

small bunsen flame.3. Using a sterile swab, place it at the end of the wire

loop and wipe your desk to check if there are bacteria there).

4. Make a zig zag streak on the surface of the agar in the new petri dish.

5. Place the lid on the petri dish and seal it with tape.6. Place the petri dish in an incubator at 37oC or over a

warm water bath over a bunsen burner (the water bath must be kept at around 37oC and not more).

7. After a day or two examine the dish to see if any bacteria have grown.


Bacteria replicate every 20 minutes.

So after 20 minutes there will be 2Bacteria.

After 40 minutes there will be 4Bacteria

After one hour there will be 8Bacteria

After one hour 20 minutes thereWill be 16 bacteria

After one hour 40 minutes there willBe 32 bacteria.

After two hours there will be 64 Bacteria.

Characteristics of Insects:1. Exoskeleton2. Jointed appendages3. Head, thorax and abdomen

In the phylum Chordata, the class amphibians (frog) performs metamorphosis


Phylum Chordata• Fish and

Amphibians and Reptiles are cold blooded.

• Birds and Mammals are warm blooded.

class features examples

amphibians moist permeable

skin

frog, newt, salamander

fish gills, wet scales goldfish, shark, cod

reptiles dry scales crocodile, lizard, snake

birds feathers, beaks budgerigar, sparrow, ostrich

mammals fur, produce, milk

rabbit, kangaroo, human, dolphin


Class Fish

• Breathe using gills.

• Covered with scales.


Class Amphibians

• Can live part of their lives on land and part in water.

• Grow by metamorphosis e.g. frog hatches from egg, becomes tadpole, and grows into a frog.


Class Reptiles

• Hard scaly skin.


Class Birds

• Covered with feathers


Class Mammals

• Have mammary glands and suckle their youngs with milk

• Have their body covered with hair or fur.
