7. You have an unknown microorganism that you would like to classify as archaeabacteria, eubacteria, fungi, protozoa, or virus. Please describe how you might classify this organism based on its physical characteristics. As part of your answer, describe specific characteristics of each of the 5 groups above.

Expert Solution

1) Characteristics of Archeabacteria: -

-. Archeabacteria do not possess the well developed nuclear envelope,so they are considered as prokaryotic organisms.

- Due to the preencpr of glycerol- ether lipids in the cell wall they can live in extreme environmental conditions. Wheras the other common bacteria have glycerol ester lipids .

-. They possess isoprenoid units in the composition of their fatty acid tails.

2 ). Eubacteria:-

- The bacteria are prokaryotic as they lack the well developed nuclear envelope.

- On the basis of cell wall composition they are mainly classified into Gram negative bacteria and Gram positive bacteria.

- They have flagella for the movement.

- They have various forms according to their shapes like Bacillus,coccous and so on.

3) Fungi :-

- It is considered as the lower plant group .

- .Fungi lack the chlorophyll pigment,so they can't produce their own food material. Therefore they are considered as heterophytes.

-. According to the mode of their nutrition they are classified as ,parasitic fungi and saprophytic fungi.

4) Protozoa : -

- . These are the single celled eukaryotic microorganisms.

-. They are parasitic in Nature.

- . They belongs to the kingdom protista.

5) . Viruses:-

- .Viruses are microscic in nature .

- Virus is composed of protein ,lipids and the genetic material.

- The genetic material of virus is surrounded by protein coat .

-. Using host enzymes they can replicate their DNA and incorporate their DNA in host call and multiply themselves.

Part A) You have 67 grams of a unknown material, and you would like to find out its specific heat. You decide to heat it up to 100 C and put it in a 66 g aluminum cup (specific heat = 0.22 cal/(g C) that 200 grams of water (specific heat = 1 cal/(g C)). Usually this aluminum cup is in another cup so that the system is insulated. If both the cup and the aluminum cup are initially at...

Lichens are actually two organisms, fungi and a photosynthetic microorganism, living together.

LICHENS Lichens are actually two organisms, fungi and a photosynthetic microorganism, living together. Typically, lichens are comprised of cyanobacteria or green algae in a mutualistic relationship with an ascomycete fungus. The algae contribute food from photosynthesis and the fungus contributes anchorage and water retention. The lichen body, called a thallus, can be found on bare rock, soil, hanging from trees, and many harsh living environments. Lichens are generally the first organisms to colonize cleared rock and soil surfaces after volcanic activity...

what are real microorganism that may be of positive use or a microorganism that may have a positive impact on something else (a prokaryote, a eukaryote, an acellular agent) and focus on any aspect of the microorganism – for example structure(s) and/or function(s) – that may have any positive outcome, use, or impact. (1) that it must be within the natural capabilities of the microorganism and must be original.
