These are all examples of local  anaesthetics a) marcaine(Bupivacaine) b) xylocaine(lidocaine) c) novocain(procaine) are all  examples of local anaesthesia

Explanation:

Generally local anaesthetic are drugs used in clinical anaesthesia  to block or  suppress the sensation  of pain  at the specific  region or part of the body where it was applied.The effect of the application depends on the dose applied and the period of application.

The work  by inhibiting transmission of action potential as nerve transmission,through blocking of sodium channels. Thus depolarization is prevented,and nervous transmission to the brain (and therefore pain)  is suppressed

Generally pain transmission fibres are blocked first,motor sensation are lost afterwards ,therefore touch sensation and pressure are the last to be lost by the local region.

They are classified into  Amide or ester group based on the chemical structures.The  examples in the question are amides.

Subcutaneous or epidural administrations  can be used to apply

Your body is supported by your skeleton, which also holds your internal organs in place. The body would be floppy, like a jellyfish, without bones. Your muscles and organs have a framework to connect, thanks to your bones. The vertebral column (backbone) is what keeps your body upright.

Because bones are strong and hard, they can protect vital internal organs from harm. For example:

Bones are attached to muscles. A bone will move as a result of a muscle pulling on it. The skeleton is flexible at joints like your knee. The body may move because of how bones move around joints.

Your body has some hollow bones, such as the long ones in your arms and legs. A soft tissue called bone marrow is located in the middle of these bones. Red and white blood cells are created in the bone marrow. White blood cells are used to fight infection, whereas red blood cells are used to transport oxygen throughout the body.

Fermentation breaks down the glucose when no oxygen is available in order to make some ATP, hence option a is correct.

Glycolysis, the first step in fermentation, converts glucose into two pyruvate molecules, two ATP (net), and two NADH.

The constant breakdown of glucose to produce ATP during fermentation is made possible by the recycling of NADH to NAD+, to produce lactic acid and alcoholic fermentation.

Therefore, the fermentation's need for anaerobiosis is made easier by the carbon dioxide that is created in place of the air, hence option a is correct.

Mutation produce changes in the DNA sequence of a gene can eventually lead to the evolution of new species.

In the field of Biology, a mutation can simply be described as a change that occurs in the DNA of an organism.

Usually, a mutation can occur in such part of the DNA that sis junk and hence such mutation are not harmful. Other times, it might happen that after mutation, the gene might still be coding for the same protein. In such a case also, the mutation is not harmful.

However, if a mutation causes changes in the DNA sequence of a gene, which in turn starts coding for another protein, then such a genetic mutation can lead to evolutionary changes. Such DNA changes can also lead to the formation of new species.

No, targeting flagellin, the primary structural component of bacterial flagella, does not pose a significant risk of attacking human cells.

The primary structural component of bacterial flagella, flagellin, is specific to bacteria and not found in human cells.

Therefore, a medication targeting flagellin would not pose a significant risk of attacking human cells.

The development of antibiotics that specifically target bacterial components, such as flagellin, is a promising approach to combat bacterial infections.

These antibiotics aim to disrupt essential bacterial functions or structures without affecting human cells, minimizing the risk of toxicity or harmful side effects.

However, it is important to note that antibiotic development and testing are complex processes. While the primary target of the medication may be flagellin, thorough research and testing are necessary to ensure its safety and effectiveness.

The medication's selectivity and specificity for bacterial flagellin should be confirmed through preclinical and clinical trials to assess its efficacy against bacterial infections while minimizing potential off-target effects.

In summary, a medication targeting flagellin, the primary structural component of bacterial flagella, would not pose a significant risk of attacking human cells, as flagellin is specific to bacteria and absent in human cells.

Nonetheless, further research and testing are crucial to validate the medication's specificity, efficacy, and safety.

The change from gill breathing to ling breathing was accompanied by important changes in the respiratory system and circulatory system.

Let's discuss both systems briefly:

Respiratory System: There were important changes in the respiratory system, specifically in the evolution of the lungs. Lungs are much more effective than gills at extracting oxygen from the air and disposing of carbon dioxide, which has helped animals to be able to live in drier environments away from water sources.

Therefore, one of the significant changes that happened with the change from gill breathing to lung breathing is the development of lungs in the respiratory system.

Circulatory System: The circulatory system also underwent important changes in the evolution of animals. Blood circulation was changed to fit the new respiratory system of the lungs. Lungs are less effective at extracting oxygen from the air than gills, which means the blood had to be more effectively circulated to deliver oxygen to cells in the body. So, the circulatory system has to become more efficient to keep up with the oxygen demand that lungs need.

The respiratory and circulatory systems work together to enable oxygen to diffuse into the bloodstream and carbon dioxide to be removed from it, resulting in a constant supply of oxygen to cells in the body.

Living systems follow the laws of conservation of mass and energy as the starting compounds and energy absorbed by photosynthesis change to something new, but they never disappear. In other words, the mass and energy of the reactants are conserved in the products of a chemical reaction.

However, energy can transform from one form to another, but it can neither be created nor destroyed as stated in the law of conservation of energy. Photosynthesis shows the conservation of mass and energy as it takes in carbon dioxide and water and produces glucose and oxygen.

All the atoms in the starting reactants are conserved in the end products. Therefore, the mass of the reactants equals the mass of the products.Food and oxygen are produced during the process of photosynthesis through the transformation of energy. Chlorophyll, a green pigment present in all plants, absorbs sunlight to provide energy for photosynthesis.

Chloroplast, an organelle that contains chlorophyll, is the place where photosynthesis takes place. During this process, energy is converted into chemical energy, and glucose is produced to store this chemical energy. Oxygen is also released as a byproduct of photosynthesis.

The separation of double-stranded and single-stranded DNA in polymer solutions is based on the mobility and separation mechanism. In such solutions, the mobility of DNA molecules is influenced by the interactions between the DNA and the polymer molecules present in the solution.

Polymers such as polyacrylamide or agarose are commonly used in gel electrophoresis to separate DNA strands based on their size and charge. In gel electrophoresis, an electric field is applied to the gel matrix containing the DNA samples. The negatively charged DNA molecules move towards the positive electrode, with smaller fragments moving faster than larger ones.

In a polymer solution, the polymer molecules form a network or matrix that slows down the movement of DNA molecules. This network provides a sieving effect, allowing smaller DNA strands to pass through more easily than larger ones. As a result, the DNA strands are separated based on their size.

The separation mechanism is based on the fact that single-stranded DNA is generally more flexible and can move more easily through the polymer matrix compared to double-stranded DNA. This difference in mobility allows for the separation of the two types of DNA strands.

In summary, the separation of double-stranded and single-stranded DNA in polymer solutions is achieved through gel electrophoresis, where the mobility and separation mechanism are influenced by the interactions between the DNA and polymer molecules present in the solution.
