Rhea Patel answered |
Explanation:
Penicillin is an antibiotic drug that was discovered by Alexander Fleming in 1928. It is used to treat bacterial infections caused by sensitive bacteria. Penicillin is a member of the beta-lactam family of antibiotics, which means that it contains a beta-lactam ring in its chemical structure.
Interference in Metabolic Pathway of Bacteria:
Penicillin works by interfering in the metabolic pathway of bacteria. Bacteria require cell wall synthesis for their growth and survival. The cell wall is a complex structure that surrounds the bacterial cell and provides protection and support. The cell wall is primarily composed of peptidoglycan, a mesh-like structure of sugar and amino acids.
Penicillin interferes with the cell wall synthesis of bacteria by inhibiting the enzyme transpeptidase, which is responsible for cross-linking the peptidoglycan strands. Without the cross-links, the cell wall becomes weak and unable to withstand the high osmotic pressure of the bacterial cytoplasm. As a result, the bacterial cell undergoes lysis (rupture) and dies.
Penicillin is effective against a wide range of bacteria, including Streptococcus pneumoniae, Staphylococcus aureus, and Neisseria gonorrhoeae. However, some bacteria have developed resistance to penicillin by producing enzymes called beta-lactamases, which break down the beta-lactam ring and render the drug ineffective.
Conclusion:
In conclusion, penicillin is an antibiotic drug that works by interfering in the metabolic pathway of bacteria. It inhibits the enzyme transpeptidase, which is responsible for cross-linking the peptidoglycan strands in the bacterial cell wall. Without the cross-links, the cell wall becomes weak and unable to withstand the high osmotic pressure of the bacterial cytoplasm, which leads to cell lysis and death.

Chronic Diseases Cause More Health Hazard than Acute Diseases
Chronic diseases are long-lasting medical conditions that are generally progressive in nature and do not have a specific cure. In contrast, acute diseases are generally short-lived and can be cured with proper treatment. Both chronic and acute diseases can lead to health hazards, but chronic diseases are more likely to cause more damage to a person's health than acute diseases.
Causes of Chronic Diseases
The causes of chronic diseases are multifactorial and can vary depending on the disease. Some of the common causes of chronic diseases include:
- Poor lifestyle choices such as lack of physical activity, unhealthy diet, and smoking
- Genetic factors
- Environmental factors such as pollution and exposure to toxins
- Chronic infections
Health Hazards of Chronic Diseases
Chronic diseases can lead to several health hazards such as:
- Reduced quality of life
- Increased healthcare costs
- Disability and loss of productivity
- Premature death
Chronic diseases can also increase the risk of developing other medical conditions such as heart disease, stroke, and cancer.
Prevention and Treatment of Chronic Diseases
Preventing chronic diseases involves making healthy lifestyle choices such as engaging in regular physical activity, maintaining a healthy diet, and avoiding smoking. Regular health check-ups can also help in detecting chronic diseases early, which can improve the chances of successful treatment.
Treatment for chronic diseases depends on the type of disease and its severity. Treatment generally involves managing symptoms, slowing down the progression of the disease, and preventing complications. Some chronic diseases can also be cured with proper treatment, such as certain types of cancer.
Conclusion
In conclusion, chronic diseases cause more health hazards than acute diseases. Chronic diseases are long-lasting and progressive in nature and can lead to several health hazards such as reduced quality of life, increased healthcare costs, disability, and premature death.

Sushil Solanki answered |
Answer:
The correct answer is C: Cold and cough.
Explanation:
Therefore, the correct answer is C: Cold and cough.
The correct answer is C: Cold and cough.
Explanation:
- Elephantiasis: Elephantiasis is a chronic disease caused by the parasitic infection of the lymphatic system. It is characterized by the swelling and thickening of the skin and underlying tissues, typically in the legs and genitals.
- Tuberculosis: Tuberculosis (TB) is a chronic infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB can be a life-threatening condition if not treated properly.
- AIDS: Acquired Immunodeficiency Syndrome (AIDS) is a chronic disease caused by the Human Immunodeficiency Virus (HIV). It weakens the immune system, making individuals more susceptible to infections and diseases. AIDS is a serious condition that can lead to death if left untreated.
- Cold and cough: Cold and cough are acute illnesses caused by viral infections. While they can be recurrent, they are not considered chronic diseases as they typically resolve within a few days or weeks.
Therefore, the correct answer is C: Cold and cough.

Gargi Das answered |
Explanation:
Antibiotics are drugs that are used to treat bacterial infections. They work by targeting specific biochemical pathways that are unique to bacteria. These pathways are essential for the survival of bacteria, but are not present in human cells. Therefore, antibiotics can selectively kill bacteria without harming human cells.
Why antibiotics don't work against viral infections:
Viruses are very different from bacteria. They are much smaller and simpler in structure, and they do not have the same biochemical pathways as bacteria. This means that antibiotics, which are designed to target bacterial pathways, are ineffective against viruses.
How viruses work:
Viruses are essentially packets of genetic material (DNA or RNA) surrounded by a protein coat. They cannot reproduce on their own. Instead, they must invade a host cell and hijack its machinery in order to replicate themselves. Once inside a host cell, a virus will use the cell's own machinery to produce more viral particles, which can then infect other cells.
Why antibiotics are not effective against viruses:
Antibiotics are designed to target specific biochemical pathways that are unique to bacteria. These pathways are not present in viruses. Therefore, antibiotics have no way to target the virus itself. They may be able to kill any bacteria that are present in the body, but they will not have any effect on the virus.
The dangers of overusing antibiotics:
Overusing antibiotics can lead to the development of antibiotic-resistant bacteria. When antibiotics are used excessively, bacteria can evolve to become resistant to them. This means that the antibiotics will no longer be effective against these bacteria. This is a major public health concern, as antibiotic-resistant bacteria can be very difficult to treat, and can lead to serious infections that are resistant to all known antibiotics. Therefore, it is important to use antibiotics only when they are needed, and to follow the instructions of the doctor or pharmacist carefully.

Once inside a host cell, a virus will use the cell's own machinery to produce more viral particles, which can then infect other cells.
Why antibiotics are not effective against viruses:
Antibiotics are designed to target specific biochemical pathways that are unique to bacteria. These pathways are not present in viruses. Therefore, antibiotics have no way to target the virus itself. They may be able to kill any bacteria that are present in the body, but they will not have any effect on the virus.
The dangers of overusing antibiotics:
Overusing antibiotics can lead to the development of antibiotic-resistant bacteria. When antibiotics are used excessively, bacteria can evolve to become resistant to them. This means that the antibiotics will no longer be effective against these bacteria. This is a major public health concern, as antibiotic-resistant bacteria can be very difficult to treat, and can lead to serious infections that are resistant to all known antibiotics. Therefore, it is important to use antibiotics only when they are needed, and to follow the instructions of the doctor or pharmacist carefully.

AIDS stands for acquired immunodeficiency syndrome, a disease that makes it hard for the body to fight off infectious diseases. HIV, the virus which causes AIDS, can be spread through unprotected sexual intercourse (can still be spread using a condom, but it’s a lot rarer), blood transfusion with HIV infected blood, and breast milk.
The most common cause of non-sexual HIV transmission is mother-to-child. If a woman infected with HIV or AIDS has a baby, there’s a chance the baby will be infected in the womb, or become infected after birth through the breast milk. This is why it is not recommended that HIV-positive women breastfeed, and a lot of developing countries have education and support groups for new mothers warning of this.

Jaundice can happen if your baby's liver doesn't work well. This may be because of an infection or other factors. The liver is the part of the body most responsible for getting rid of bilirubin. A problem with the liver can cause higher levels of bilirubin.

Many animals which live with us carry disease. These animals transfers infecting agents from sick person to another potential host (healthy person) and act as vectors. Mosquitoes are known to cause many diseases.

Protozoan Diseases:
Protozoans are single-celled organisms that can cause diseases in humans. They are found in various environments, including water, soil, and inside other organisms. One of the most common diseases caused by protozoans is malaria.
Malaria:
Malaria is a disease caused by the protozoan Plasmodium. It is transmitted through the bites of infected female Anopheles mosquitoes. The symptoms of malaria include fever, chills, headache, muscle pain, and fatigue. In severe cases, it can lead to complications such as anemia, kidney failure, and cerebral malaria.
Other Diseases:
Influenza, AIDS, and Cholera are not caused by protozoans. Influenza is caused by a virus, AIDS is caused by the human immunodeficiency virus (HIV), and Cholera is caused by the bacterium Vibrio cholerae.
Prevention and Treatment:
Prevention and treatment of malaria involve control of mosquito populations, use of insecticide-treated bed nets, and anti-malaria drugs. There is no effective vaccine for malaria, but research is ongoing. Other measures to prevent the spread of protozoan diseases include proper sanitation practices, water treatment, and avoiding contact with infected individuals.
