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.

Human rights include the right to life and liberty, freedom from slavery and torture, freedom of opinion and expression, the right to work and education, and many more.

In humans, one function of the skin is to prevent water loss. Skin releases water or holds in water when necessary.Which two structures in plants have a similar function to skin?


> roots and chloroplasts

> phloem and roots

> cuticle and stomata

> stomata and phloem

Answers

Cuticle and stomata in plants have a similar function to skin.

What are the functions of cuticles?

The cuticle is well known for its functions as a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack.

In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.

The cuticle itself comprises three layers: the cuticular layer; cuticle proper; and epicuticular waxes. The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.

Explanation:

The cell cycle of yeast cells grown in the nutrient-poor environment is approximately what percent of the cell cycle of yeast cells grown in the nutrient-rich environment.

Answers

The cell cycle of yeast cells grown in the nutrient-poor environment is approximately 168 % of the cell cycle of yeast cells grown in the nutrient-rich environment. Hence option 1 is correct.

What is cell cycle?

Cell cycle is defined as the cascade of cellular activities that lead to cell division into two daughter cells. The primary purpose of the cell cycle is to accurately divide the enormous amount of DNA found in the chromosomes into two daughter cells that are genetically identical. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide.

The interphase and M-phase are the two phases that make up the cell cycle. About 90% of the cycle is made up of interphase, during which the cell develops and copies its chromosomes in order to divide. Undifferentiated ESCs have a G1 and S cell cycle percentage of 15-20% and 60–70%, respectively, however as the ESCs differentiate, this ratio changes.

Thus, the cell cycle of yeast cells grown in the nutrient-poor environment is approximately 168 % of the cell cycle of yeast cells grown in the nutrient-rich environment. Hence option 1 is correct.
