Answer 1

Answer:

Answer:

E. lack peptidoglycan, are the smallest free-living organisms AND have sterols in their membranes.

Explanation:

Mycoplasmas are also called pleuropneumonia-like organisms (PPLO) are the smallest free-living, prokaryotic organisms. They do not have a cell wall and is bounded by a plasma membrane which contains sterol.

Since cell wall is absent in them, they lack peptidoglycan. These are present in animals, plants, insects, soil and sewage. They grow better in the aerobic environment but can also live as facultative anaerobes.

Mycoplasma cause infection, affects cell metabolism, gene expression.

Where does carbon come from in a winogradsky column? 2. why is carbon important? 3. what purpose does calcium sulfate serve in the winogradsky column? 4. why is a hydrogen sulfide gradient generated from bottom to top in a winogradsky column? 5. how is photosynthesis different between cyanobacteria (growing at the top of the column) and green and purple sulfur bacteria (growing near the bottom 1/3 of the column)?

Answers

Answer:

1.The Winogradsky section is a straightforward gadget for refined an enormous decent variety of microorganisms.The gadget is a segment of lake mud and water blended in with a carbon source, for example, paper which contains cellulose, darkened marshmallows or egg-shells which contains calcium carbonate.

2. carbon is important for providing cellulose for winogradsky column.

3.calcium sulphate in the form of gypsum or plaster of paris, craft or garden stores is used. green suphur bacterias and purple sulphur bacterias are formed after 2 to 6 weeks.

4.A hydrogen sulfide slope is created from the base to top in a Winogradsky section since sulfur-decreasing microorganisms like Desulfovibrio (microbes that utilizes maturation side-effects like Ethanol and Organic acids from Clostridium as a carbon source by means of anaerobic breath) produce a lot of H2S as a result of anaerobic breath. The H2S gradually diffuses upwards and is utilized by different life forms. The explanation the angle is higher at the base is on the grounds that anaerobic microscopic organisms like Desulfovibrio can't endure where O2 is available. The further down in a Winogradsky section the more anaerobic the earth. Along these lines, bigger measures of H2S are created at base of segment in light of the fact that there is a higher grouping of anaerobic microorganisms that produce H2S at the base as side-effect of their anaerobic breath process

5.Rather than utilizing water to photosynthesize, similar to plants and cyanobacteria, purple sulfur microscopic organisms use hydrogen sulfide as their decreasing operator, which is the reason they radiate sulfur as opposed to oxygen.

Explanation:

Carbon comes from blackened marshmallow or egg-shells, newspapers which contain cellulose, and sulphur source, for example, calcium sulphate in winogradsky column.
Carbon is important because it promotes the growth of different microorganisms. For example chlorobium, chromatium, rhodomicrobium, and Beggiatoa.
Hydrogen sulphide gradient is generated from bottom to the top in a winogradsky column because they dominate the zone with sulphur which reduces bacteria.
Photosynthesis is different between cyanobacteria and green and purple sulphur which is sulphur anaerobic bacteria being the top layer of aerobic bacteria which produces carbon dioxide which feeds back into the column by creating another reaction.
