What bacteria lack in the cytoplasm?

The bacteria that lack cytoplasm, is the eukaryotic cells. These cells do not contain cytoplasm, and they are also not a bacteria that can replicate on its own.

How many night crawlers in a 5 gal bucket to harvest compost in 2 weeks?

There is no specific answer for this one, because some worms will work faster than others at certain types of things. If I were you, I'd just buy two or three tins of live bait, pour them all in, and hope for the best.

The compost will get really warm in certain places as bacteria break it down, so be sure to turn it.

What is biological bacteria?

There many kinds of biological bacteria. These include yeast, fungal flora, archaea, conjunctivitis, stomach and intestinal flora, respiratory flora, and many more.

Which type of microrganisim is the smallest?

A prion is a small infectious particle that contains a misfolded protein. These contain no DNA or RNA. These cause Creutzfeldt-Jakob disease, Scrapie in sheep and Kuru. These are deadly and progressive nerve wasting diseases.

A plant pathologist discovered an infectious RNA particle smaller than a virus that causes diseases in plants. He called it a viroid. Millions each year are lost by these viroids. These contain only RNA.

These two are the smallest infectious particles. They are not called microorganisms because they are not alive any more than viruses are.

What is log 6 bacteria?

In studying the process of the sterility assurance level, which is how you guarantee the sterility of a sample of bacterium, each log reduction assures that 90% of the sample is sterile, so log 6 reduction just ensures it further.

Are most bacteria photoautotrophs?

No. They are heterotrophs just as you are. They are not usually green as photoautotrophs. They would not be close to the air to get sunlight.

What kind of bacteria is ''amoeba''?

Amoeba is not a bacteria. It comes in animal kigdom. It is unicellular organism. Such organisms are called as protozoa. It has no cell wall like bacteria do.

What type of taxis is a bacterial cell exhibiting when it moves toward glucose in the environment?

Chemotaxis - this is the general term for bacterial motility when sensing a compound in the environment. If moving toward it is called positive chemotaxis, if away from it is negative chemotaxis.

Do bacteria have adapted better to life on the earth than human?

There a pro's and Con's to this.

Yes to the point that they are single celled organisms so they can easily sit around in a warm, damp and nutritious place (Known as your food recycling bin) and reproduce without a care of anything else. [Parasites are awesome as well as they just live off a host and no nothing... they get their warmth, dampness and food from just living inside of you. But don't keep them as a pet otherwise there is a chance of death]

No, as they can't survive if you take one of those things away. And I don't see them creating Bio-domes in the middle of deserts or space stations orbiting the Earth.

It depends on how you look at it and under what category you set it. Eg) Can you send them into space on a rock: Yes to Bacteria and No to Humans.

Can they adapt to different climates: No to Bacteria and Yes to Humans.

Why is naturally occurring transformation beneficial to bacteria?

Transformation could allow the organism to become pathogenic, allows microorganism to develop new characteristics or abilities and to acquire new genes.

When observing your microscope slide you are unable to locate any bacteria what are some possible reasons for this observation?

  1. There are no bacteria on the slide.
  2. Your lens cap is on.
  3. You are not looking in the right place.
  4. The microscope is in the wrong focus.

Can plants and and animals survive without bacteria?

No. They could not under the current regime of life on Earth. Bacteria, in their symbiotic, detrivorous, and other roles are critical to the life functions of plants and animals.

If all bacteria were to die out, it is likely that everything living on the planet would die out. Oddly enough, the bacteria could survive without animals or plants.

What are the 3 beneficial effects of coccus bacteria?

Bacteria help to build immunity to diseases, they help to develop medications like penicillin, and they help to ferment food and drink.

What relationship do you have with bacteria in your gut?

This is a symbiotic relationship, since you rely upon the fauna in your intestinal tract to help digest your food and it relies on you to supply food.

Why is yoghurt made at 37 degrees?

Yoghurt mixtures are incubated to ensure multiplication of lactic acid bacteria. This means that lactic acid will be produced, which will give the product good flavour and texture and extend shelf life.

What do the promoter region do in the DNA translation?

The promoter region has no role in translation. It is the site where RNA Polymerase binds to initiate transcription. Basically, talking about bacteria, a protein called sigma70 binds to the promoter and recruits the RNA Polymerase enzyme. After the RNA Pol is recruited, the sigma70 factor is released and RNA Polymerase synthesizes the complementary mRNA from the DNA that is being transcribed.

What does bacteria receive energy from?

Different types of bacteria acquire energy from different sources. For example, Cyanobacteria, some purple and green bacteria, get energy from light. Most bacteria use organic compounds for energy. Most bacteria are saprobic and get energy from dead organic matter .

What is the number of cells in domain bacteria?

The number of cells in the domain Bacteria is estimated to be in the range of 10^30 to 10^31 cells. This estimate is based on the vast diversity and abundance of bacterial cells in various environments on Earth.

What was Anabaena azollae do that Escherichia coli cannot do?

Anabaena azollae fixes atmospheric nitrogen into ammonia that is donated to it's symbiotic host. E. coli reduces nitrate to nitrite.

What are three methods that are used to identify bacteria?

Three common methods used to identify bacteria include Gram staining, biochemical tests, and molecular techniques such as polymerase chain reaction (PCR) or sequencing of the bacterial genome. These methods help to determine the characteristics of the bacteria, such as cell wall composition, metabolic characteristics, and genetic makeup, which aid in identification.

What type of food properties allow harmful bacteria to multiply rapidly?

There are various food properties that allow harmful bacteria to multiply rapidly; one being the food is low in acid. Two more are moisture and that the food is high in protein.
