Answer 1

Answer:

1. Reproduction in bacteria reproduces by binary fission. Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction and reproduction of yeast occurs by budding.
2. Microbes, or microscopic organisms, are widely used in large-scale industrial processes. They are crucial for the production of a variety of metabolites, such as ethanol, butanol, lactic acid and riboflavin, as well as the transformation of chemicals that help to reduce environmental pollution
3. Bacteria can obtain energy and nutrients by performing photosynthesis, decomposing dead organisms and wastes, or breaking down chemical compounds. Bacteria can obtain energy and nutrients by establishing close relationships with other organisms, including mutualistic and parasitic relationship.

Answer 2

Answer:

Hey mate

Explanation:

reproduction in bacteria reproduce by binary fission in bacteria grow to fixed size and then reproduce their Binary fusion a form of a sexual reproduction and Reproduction of yeast occurs by budding here is a small bud daughter cell is formed on the parent cell.

Microbes, or microscopic organisms, are widely used in large-scale industrial processes. They are crucial for the production of a variety of metabolites, such as ethanol, butanol, lactic acid and riboflavin, as well as the transformation of chemicals that help to reduce environmental pollution.

Bacteria obtain their nourishment through the absorptive mode of nutrition. They secrete the extracellular digestive enzymes through the Secretion system, present in the bacterial membrane. ... Then they absorb the digested simpler form of the nutrient(food).

The main types of antibiotics include:

Penicillins - for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin.

Cephalosporins - for example, cefaclor, cefadroxil and cefalexin.

Tetracyclines - for example, tetracycline, doxycycline and lymecycline.

Aminoglycosides - for example, gentamicin and tobramycin.

Canned and sealed food are generally safe to eat but sometimes some bacteria can cause disease can survive and also some harmful chemicals that are used for its inner coating, so before buying any canned food it should be checked and fresh food should be preferred.
