HIV is a disease caused by the human immunodeficiency virus, which leads to the progression of acquired immunodeficiency syndrome (AIDS). The virus targets the immune system, specifically the CD4 cells, weakening the body’s ability to fight off infections and diseases. HIV is transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It can also be passed from mother to child during childbirth or breastfeeding. Early symptoms of HIV may include flu-like symptoms, but the disease can progress without noticeable symptoms for years. If left untreated, HIV can advance to AIDS, which is characterized by a severely weakened immune system and an increased risk of opportunistic infections and certain cancers. Treatment for HIV involves antiretroviral therapy, which can control the virus and prevent the progression to AIDS, allowing individuals to live longer, healthier lives.
AIDS virus, also known as HIV (Human Immunodeficiency Virus), is a single-stranded RNA virus. This virus belongs to the retrovirus family and has a genome composed of single-stranded RNA.

AIDS virus, also known as HIV (Human Immunodeficiency Virus), is a single-stranded RNA virus. This virus belongs to the retrovirus family and has a genome composed of single-stranded RNA. When HIV enters a host cell, it uses the enzyme reverse transcriptase to convert its RNA genome into DNA. This DNA then integrates into the host cell’s genome, allowing the virus to replicate and spread within the body. HIV attacks the immune system, specifically targeting CD4 cells (T cells), which weakens the immune response and makes the body susceptible to opportunistic infections and certain cancers. As the virus progresses and the immune system becomes severely compromised, the condition known as Acquired Immunodeficiency Syndrome (AIDS) can develop. Effective antiretroviral therapy can control the virus and improve the quality of life for those living with HIV/AIDS.
AIDS is spread by physical contact [D] through the exchange of bodily fluids. The transmission routes include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during childbirth or breastfeeding.

AIDS is spread by physical contact [D] through the exchange of bodily fluids. The transmission routes include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during childbirth or breastfeeding. Additionally, blood transfusions with contaminated blood can spread HIV, which causes AIDS. Casual contact, such as shaking hands, hugging, or sharing food, does not transmit the virus. AIDS is not spread through respiratory contact like coughing or sneezing, nor is it transmitted by insects such as mosquitoes. Preventing the spread of HIV involves practicing safe sex, using clean needles, and ensuring safe blood transfusions. Public health initiatives aim to educate individuals on safe practices and provide testing and treatment to reduce the risk of transmission.
: A virus consists of nucleic acid and protein. The nucleic acid, which can be either DNA or RNA, contains the virus's genetic information.

: A virus consists of nucleic acid and protein. The nucleic acid, which can be either DNA or RNA, contains the virus’s genetic information. Surrounding the nucleic acid is a protein coat called a capsid, which protects the genetic material and aids in the virus’s attachment to host cells. In some viruses, there may also be a lipid envelope derived from the host cell’s membrane that surrounds the capsid, providing an additional layer of protection. Carbohydrates are not a primary component of viruses, but they may be present as part of the lipid envelope in some cases. Therefore, the primary components of a virus are nucleic acid and protein.

SARS is a viral disease. It stands for Severe Acute Respiratory Syndrome, which is caused by the SARS coronavirus. This virus leads to serious respiratory illness in infected individuals, with symptoms such as fever, cough, and difficulty breathing. SARS was first identified in 2002 and caused an outbreak that spread to multiple countries. The disease can be severe and may result in pneumonia, acute respiratory distress syndrome, and sometimes death. Precautions such as quarantine, travel restrictions, and public health measures were implemented during the outbreak to control its spread. Scientists have since studied the virus to develop diagnostic tests, treatments, and potential vaccines.

Measles is caused by a virus. The measles virus is highly contagious and spreads through respiratory droplets when an infected person coughs or sneezes. Symptoms typically begin with a high fever, cough, runny nose, and inflamed eyes, followed by a red rash that usually starts on the face and spreads to the rest of the body. Complications from measles can include pneumonia, encephalitis, and other serious health issues. Vaccination is the most effective way to prevent measles and its complications. The measles vaccine is often combined with mumps and rubella vaccines in the MMR vaccine, which is recommended for children and adults who have not been vaccinated.

Smallpox is caused by a virus. Specifically, it is caused by the variola virus, which is part of the orthopoxvirus family. Smallpox was a serious, contagious disease that caused high fever and a characteristic rash with pus-filled blisters. It had a high mortality rate and often left survivors with severe scarring. However, due to widespread vaccination efforts, smallpox has been eradicated globally since the late 1970s. Tuberculosis, on the other hand, is caused by bacteria, while malaria is caused by a parasite, and cholera is caused by bacteria. Therefore, smallpox is the only disease in the list that is caused by a virus.

Foot and mouth disease in animals is caused by a virus. This disease is caused by the foot-and-mouth disease virus, which belongs to the Picornaviridae family and the genus Apthovirus. Foot and mouth disease (FMD) in cattle is caused by a virus – picornavirus. It is a highly contagious disease that affects cloven-hoofed animals such as cattle, pigs, sheep, goats, and other animals. Symptoms of the disease include fever, blisters, and sores in the mouth and on the hooves, leading to lameness. The disease can spread rapidly through direct contact with infected animals or contaminated feed, equipment, and clothing. Although foot and mouth disease does not typically infect humans, it can have a significant economic impact on the livestock industry. Control measures include vaccination, culling infected animals, and movement restrictions to prevent the spread of the virus.

The causative agent of mosaic disease in potato is a virus. This disease is caused by several types of viruses, including potato virus Y, potato leaf roll virus, and others. These viruses lead to characteristic symptoms in potato plants, such as mottled or mosaic patterns on the leaves, stunted growth, and reduced tuber quality and yield. The viruses are transmitted through infected plant material, aphids, or mechanical means. Management of mosaic disease involves using virus-free seed potatoes, controlling aphid populations, and removing infected plants to prevent the spread of the viruses. By implementing these practices, farmers can reduce the impact of mosaic disease on potato crops.

The cell wall of algae is primarily made of cellulose. Cellulose is a complex carbohydrate that provides structural support and protection to the cells of algae. This polysaccharide forms the main framework of the cell wall, giving it strength and rigidity. Some algae also have additional components in their cell walls such as hemicellulose, pectin, and sometimes calcium carbonate or silica, depending on the species. The cell wall helps maintain the shape of the algal cells and protects them from environmental stresses. By providing support, the cell wall allows algae to grow in various aquatic environments, including both freshwater and marine habitats.
