False

How do bacteria reproduce?
Bacteria reproduce through Binary Fission
gut
bacteria that live in your intestine help you digest food
New bacteria grow on a kitchen sponge every 2 minutes
False
When you wipe the remaining food from your dirty dishes any pathogens from your spills can fill up the holes of the damp sponge, the sponge hangs out wet and still until the next use, and at that time new bacteria grow at the surprising rate of once every 20 minutes.
What are the major parts of bacteria?
a protective cell wall
a cell membrane
a strand of DNA
flagella
Food Technology
Bacteria are very useful in food production. In the production of cheese, lactic acid bacteria which include lactobacillus and lactococcus, are used together with yeast and mold in the production. Bacteria are also used in the fermentation of food which is beneficial to health and also useful in the preservation of foods.
All of the bacteria are non motile
False
bacteria use flagella to generate different kinds of movements.
What role do bacteria play in regulating Global Ecosystems?
Bacteria break down dead organisms and waste to release nutrients. This is the process of decomposition where chemicals such as carbon, phosphorous, and nitrogen are released. They also play a significant role in nutrient cycling which is a product of decomposition. They recycle the elements that make up the living system more specifically the process of photosynthesis where organisms take up carbon dioxide and convert it into organic material.
Earwax
Earwax is made up of antibacterial components which makes it impossible for bacteria to grow inside the ear canal.
Listening to music can create bacteria
true
every single time you put your headphones on to listen to your favorite songs, you’re actually exposing yourself to millions of bacteria that mutate. Listening to music through earphones or headphones for just thirty minutes or one hour a day can multiply the number of bacteria in your ears by 700 times.
Who discovered the existence of bacteria?
Antoine Van Leeuwenhoek in 1674
Predators
