Antibiotics are derived primarily from bacteria or fungi mold , such as Penicillium. Malaria is a disease caused by protozoa that are carried by certain mosquitoes. Antibiotics, such as doxycycline, can be used in both treatment and prevention of malaria. In some cases where an antibiotic is used to treat a disease, the disease-causing bacteria or protozoa will develop resistance to the drug, meaning that that particular antibiotic will no longer be effective at destroying the resistant organisms.

Antibiotic research is a continuous process, since the need often develops for bigger and better antibiotics to wipe out resistant diseases.

You need vaccines to prevent viral diseases such as hepatitis or polio. A vaccine is a weakened form of a disease, which produces antibodies when injected in a person or animal. These antibodies allow the immune system to recognize and attack a stronger form of the disease. After you finish this article, we invite you to read other articles to assist you in teaching science at home on the Homeschool Hub, which consists of over free science articles! Home Science Tools offers a wide variety of science products and kits.

Find affordable beakers, dissection supplies, chemicals, microscopes, and everything else you need to teach science for all ages! But, we can help. Is STEM just another fad? Or are STEM fields the key that can unlock the future for not only young people but for the world? Let's dive in. Science can be split up into several fields of study. We're going to dive into what space and earth sciences are—and some of their A KWL Chart is an interactive graphic organizer that allows students to take control of their own learning by organizing existing background knowledge before, during, and after a lesson, chapter, or learning that takes place from using a science kit Because every teacher-student situation is different, there is no one science curriculum that is best for every homeschool family What are Bacteria?

Viruses: Dead or Alive? How fungi makes us sick. Commensal fungus, may play a beneficial role in our overall health. Other fungal infections can be caused by an overgrowth of commensal fungus. How to treat fungal infections.

Viruses are not living organisms, bacteria are. Viruses only grow and reproduce inside of the host cells they infect. When found outside of these living cells, viruses are dormant. Bacteria, on the other hand, are living organisms that consist of single cell that can generate energy, make its own food, move, and reproduce typically by binary fission.

This allows bacteria to live in many places—soil, water, plants, and the human body—and serve many purposes. They serve many vital roles in nature by decomposing organic matter maybe not that vital to anyone who's forgotten leftovers in the back of the fridge and by converting nitrogen, through nitrogen fixation , to chemicals usable by plants.

Bacteria even know how to work as a team through something called quorum sensing. Bacteria are giants when compared to viruses. The smallest bacteria are about 0. This makes most viruses submicroscopic , unable to be seen in an ordinary light microscope. They are typically studied with an electron microscope. Their mode of infection is different. They are the earliest forms of life to have appeared on earth.

The length of a bacteria can be up to some micrometers. Bacteria have a single-celled body due to which they lack a nucleus, mitochondria, chloroplast and other organelles. However, they exist in various shapes, from spheres and spirals to rods, having different sizes. The shape of the bacteria is characterized by their cell wall. The DNA or genetic material of a material lacks the nuclear membrane and thus they are classified as prokaryotes. The mode of gaining nutrition in bacteria is either autotrophic or heterotrophic.

Bacteria can be found in any type of environment and surroundings. They play a vital role in the maintenance of the food cycle of the ecosystem by recycling nutrients. Bacteria can either be good or bad for the human body. Good bacteria help in carrying various processes in the body whereas bad bacteria may lead to various diseases.

Bacteria are used in preparing fermented foods like yogurt , cheese, vinegar, wine, etc.
