The Good ,The Bad ,and The Ugly

Hey guys welcome back thebestscienceblog here and today I will be talking about antibiotics and how they effect our everyday life.

Bacteria are helpful and nonhelpful to us for an array of reasons. Bacteria help us because they help  digest food in our intestines.They have helped our food industry make foods like cheese, pickles, and vinegar. Bacteria are also not helpful because they are the reason we have many diseases today.

Antibiotics have proved to be the same way as bacteria. They are good and bad depending on how you use them. Antibiotics  are  drugs used to kill bacteria or stop them from reproducing. 

Doctors prescribe these to  you when you are sick and have a disease inside of you. Antibiotics are becoming less useful to fight  bacteria because they are being overused. When they are overused the antibiotics only kill the weak bacteria and let the strongest survive instead of killing all of them.

Now I will be talking about how some bacteria are harmful and get into the human body.Bacteria multiply at a fascinating rate of one new bacteria every twenty minutes. Since  bacteria reproduce so often things called genetic mutations happen a lot. 

Genetic mutations are changes in its genetic code that alter its development and growth. When this happens the bacteria can become either weaker or stronger. When they become stronger they have a higher chance of being antibiotic resistant. At this point the bacteria can make copies of themselves and make a whole community sick. 

Three bacterial diseases I will be talking about  are MRSA, Tuberculosis, and Diphtheria.

 MRSA is a super bug that has been springing up around the world. MRSA causes infections on the skin including sores and boils. It is caused by staph in our body getting infected.

Tuberculosis is a disease in which it breaks down your respiratorial tissue and forms cavities in the lungs.It often causes the person to cough up bright red blood.

Diphtheria is caused when droplets of respiratorial secretion are passed through the air. This usually happens when you cough on somebody. Symptoms are moderate fever, fatigue, or chills.


Nitrogen fixing bacteria help plants and animals by changing atmospheric nitrogen  into  fixed oxygen. This helps because  it makes it easier for the plants to give humans and animals  oxygen.

Pasteurization is the process of heating  a food, usually a liquid, to a specific temperature and time then immediately cooling it. it is important because it helps kill bad microorganisms in the food.

                        The wonderful world of Bacteria

Hello guys thebestscienceblog12 here and today I will be talking about the wonderful world of bacteria.

Originally there were only five kingdoms. Until recently all bacteria were grouped into one kingdom. This was because they had similar cell structure. The Monera kingdom  is made up of two groups called phyla. Both of them are made up of one-celled organisms called bacteria.

Bacteria were the first living things on Earth. Bacteria have always been Prokayotic cells, their nuclear material is not surrounded by a membrane. Some bacteria are able to get their  own energy through photosynthesis while others have to go out and catch it.

Bacteria  reproduce asexually through fission (shown in gif).In fission one parent cell makes a exact replica of its cell creating a baby.Bacteria also reproduce sexually through a thin tube where the two bacteria exchange genetic material. Bacteria can reproduce very fast at one every 20 minutes.






Bacteria tend to have three different shapes, sphere shaped bacteria (cocci), rod shaped bacteria (bacilli), and spiral shaped (spirilla).

The two different types of bacteria are archaebacteria and eubacteria. 

Archaebacteria were the first living things on earth. Archaebacteria can live in extreme environments including hot springs and acidic environments. They have also been found in the intestines of animals.

Eubacteria are also one celled prokaryotes. These bacteria, scientists believe, added oxygen to the Earth's atmosphere billions of years ago.
