Answer:

Prokaryotic Bacteria

Answer:

Monera is a kingdom in biology that comprises prokaryotes, which are single-celled organism that have no true nucleus.Apr 28, 2017

Explanation:

Kingdom Monera

You have suffered from a lot of diseases that bacteria cause. But, do you think all bacteria are bad? No! The bacteria have a huge kingdom of their own that consists of a number of varieties of them. Each bacteria has a different role to play. They belong to the kingdom Monera. Here, we will know all about the kingdom Monera. We will look at both their characteristics and divisions in greater detail.

Characteristics of Monera

Monera (Monos – single) includes prokaryotes and shows the following characters:

They are typically unicellular organisms (but one group is mycelial). The genetic material in these organisms is the naked circular DNA. A nuclear envelope is absent. Both, ribosomes and simple chromatophores, are the only subcellular organelles in the cytoplasm.

Sap vacuoles do not occur. Instead, gas vacuole may be present.

The predominant mode of nutrition is absorptive but some groups are photosynthetic (holophytic) and chemosynthetic.

The organisms are non-motile or move by the beating of simple flagella or by gliding.

Bacteria Shape

Cocci: They are oval or spherical in shape.

Bacilli: They are rod-shaped. They may or may not have flagella.

Vibrios: These are small and ‘comma or kidney’ like. They have a flagellum at one end and are also motile. Vibrio bacteria has a curve in its cell.

Spirillum: They are spiral or coiled like a cork­screw. The spiral forms are usually rigid and bear two or more flagella at one or both the ends e.g., Spirillum, Spirochaetes etc.

Filament: Just like fungal mycelia, the body of the bacterium is filamentous. The filaments are very minute in size. Examples include Beggiota, Thiothrix etc.

Stalked: The body of bacterium possesses a stalk e.g., Caulobacter.

Budded: The body of the bacterium is swollen at places e.g., Rhodomicrobiu

Structure of Bacteria

Capsule: In a large number of bacteria, a slimy capsule is present outside the cell wall. It is composed of polysaccharides and the nitrogenous substances (amino acids) are also present in addition. This slime layer becomes thick, called, capsule. The bacteria, which form a capsule, are’ called capsulated or virulent bacteria. The capsule ‘is usually found in parasitic forms e.g., Bacillus, anthracite, Diplococcus pneumoniae, Mycobacterium tuberculosis.

Cell wall: All bacterial cells .are covered by a strong, rigid cell wall. Therefore, we classify them under plants. Inner to the capsule, the cell wall is present. It is made up of polysaccharides, proteins and lipids. We also find D-glutamic acid and diaminopimelic acid.

Monera

Plasma membrane: Each bacterial cell has a plasma membrane. It is situated just internal to the cell wall. It is a thin, elastic and also differentially or selectively permeable membrane.

Cytoplasm: The cytoplasm refers to a complex and aqueous fluid or semifluid ground substance (matrix). This material consists of vitamins, salts, enzymes, carbohydrates, soluble proteins, co-enzymes, lipids, mineral and nucleic acids. The organic matter is present in the colloidal state.The cytoplasm is granular due to the presence of a large number of ribosomes.

Nucleoid: It has other common names like genophore, naked nucleus or incipient nucleus. There is nuclear material in these, DNA. It is double helical as well as circular. Some kind of typical protein surrounds it. However, these are not histone proteins.

Plasmids: In addition to the normal DNA chromosomes, many bacteria (e.g., E.coli) have extrachromosomal genetic elements or DNA. These elements are plasmids. They are small circular double-stranded molecules.

Flagella: These are fine, thread-like, protoplasmic appendages. These extend through the cell wall and the slime layer of the flagellated bacterial cells. These help in bacteria to swim about in the liquid medium.

Pili or Fimbriae: Besides flagella, some tiny or small hair-like outgrowths are present on the bacterial cell surface. These are pili. They comprise of pilin protein. They consequently measure about 0.5-2 mm in length and 3-5mm in diameter.

Nutrition in Bacteria

On the basis of mode of nutrition, we can group bacteria into two broad categories. First is autotrophic whereas second is heterotrophic bacteria.

Autotrophic bacteria: These bacteria are able to synthesize their own food from inorganic substances, as green plants do. They derive their carbon from carbon dioxide. The hydrogen needed to reduce carbon to organic form comes from sources such as atmospheric H2, H2S or NH3.

Heterotrophic bacteria: Most of the bacteria cannot synthesize their own organic food. They consequently depend on external organic materials. They require at least one organic compound as a source of carbon for their growth and energy. Such bacteria are heterotrophic bacteria. Heterotrophic bacteria are of three types­: Parasites, Saprotrophs and Symbionts.

The organisms that can grow at 0°C and have a maximum growth temperature of 35°C are known as psychrotrophs. These microorganisms are well adapted to cold environments and can survive in a wide range of temperatures, from freezing to moderate warmth.

Psychrotrophs are found in various environments, including soil, water, and food, and they play an essential role in the decomposition of organic matter in cold environments.

The ability of psychrotrophs to grow at low temperatures is due to the presence of specific enzymes that function optimally at low temperatures. These enzymes help the organism to maintain its metabolic rate at low temperatures and to utilize available nutrients. However, psychrotrophs can also grow at higher temperatures, up to 35°C, which is warmer than other cold-adapted microorganisms such as psychrophiles.

The growth of psychrotrophs in food can be a significant issue, as they can cause spoilage even at refrigeration temperatures. For this reason, food storage and processing methods must be carefully managed to prevent the growth of these organisms. Overall, psychrotrophs are fascinating microorganisms that have adapted to thrive in cold environments and have important implications for various fields, including biotechnology and food science.

The estimated age of the ancient wood would be 5,730 years if carbon from a sample of wood was discovered to have only half as much carbon-14 as that from a living plant.

Half life is defined as the amount of time it takes for a radioactive substance to break down or change. The half-life of a particular radioactive isotope is not influenced by the environment and is not dependent on the isotope's initial concentration.

The radioactivity of carbon-14 decays by 50% every 5,730 years. Radiocarbon dating depends on that half-life. Since carbon-12 doesn't deteriorate, it serves as a reliable indicator of carbon-14's impending demise. Older carbon-14 isotopes give off less radiation.

Thus, the estimated age of the ancient wood would be 5,730 years if carbon from a sample of wood was discovered to have only half as much carbon-14 as that from a living plant.

The primary reason for the decline in the water table in some groundwater dependent areas of the world is: a. Over-pumping

Over-pumping is the primary reason for the decline in the water table in some groundwater dependent areas of the world. When more water is pumped out of an aquifer than is being naturally replenished, the water table can lower, which can lead to a number of problems such as decreased water availability and degraded water quality.

Over-pumping can be caused by a number of factors, such as population growth, increased agricultural and industrial activity, and climate change. While lack of permeable aquifers, high rates of evaporation, and low rates of precipitation can all contribute to water scarcity in certain areas, over-pumping is the main driver of declining water tables in groundwater-dependent regions.

Both ferns and cedar trees rely on wind-dispersed pollen to successfully fertilize themselves.

Ferns are a group of vascular plants that reproduce via spores. These spores are produced in clusters called sori, which are found on the underside of fern fronds. The spores are released from the sori, and are carried away by the wind to fertilize other ferns.

Cedar trees, which are coniferous trees, also rely on wind to disperse their pollen. The male and female cones of the tree are separate, with the male cones releasing pollen into the air which is carried by the wind to fertilize the female cones on the same or nearby trees.

Both ferns and cedar tree do not produce flowers or rely on animal vectors (like bees or butterflies) for pollen transport, they use the wind to move their reproductive cells and complete the fertilization process.

Answer:

Aerobic to lactic acid fermentation pathway

Explanation:

ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.

Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.

C. Cells are the basic building blocks of all living organisms.

There are 64 codons, and only one codon (UGA) is a nonsense codon. Therefore, there are 63 codons that can mutate to become nonsense codons through a single base mutation of the second base.

A single base mutation of the second base of a codon can potentially lead to the formation of a nonsense codon, which results in premature termination of protein synthesis.

There are 64 possible codons, but only three of them serve as stop codons, which signal the end of protein synthesis. These stop codons are UAA, UAG, and UGA.

A single base mutation of the second base of a codon can lead to the formation of a different codon that codes for a different amino acid.

For example, the codon AUG codes for the amino acid methionine, but a mutation of the second base to G would result in the codon GUG, which codes for valine.

However, not all mutations of the second base result in a change to a different amino acid. If the mutation results in a stop codon, then protein synthesis will be terminated prematurely.

There are 16 possible codons that have a U as the first base and can potentially mutate to form a stop codon with a single base mutation of the second base.

This includes UAA, UAG, and UGA, as well as other codons such as UCA, UCG, UCU, and UCC.
