The main disease caused by asbestos is [A] Emphysema. Asbestos exposure can lead to various respiratory illnesses, including asbestosis, lung cancer, and mesothelioma. Emphysema, a type of chronic obstructive pulmonary disease (COPD), is characterized by the progressive destruction of lung tissue, particularly the air sacs, leading to difficulty in breathing. Unlike paralysis [B], which is typically caused by nerve damage, effervescence [C], a process of bubbling, and dysentery [D], an infectious gastrointestinal illness, asbestos-related diseases primarily affect the respiratory system due to inhalation of asbestos fibers.
Hepatitis B is caused by the [A] Virus. Specifically, it is a member of the Hepadnaviridae family. This viral infection primarily targets the liver, leading to inflammation and potentially serious liver damage.

Hepatitis B is caused by the [A] Virus. Specifically, it is a member of the Hepadnaviridae family. This viral infection primarily targets the liver, leading to inflammation and potentially serious liver damage. Hepatitis B virus (HBV) is transmitted through contact with infected blood or bodily fluids, such as during unprotected sexual activity, sharing needles, or from an infected mother to her baby during childbirth. Unlike protozoa [B] or bacteria [C], which do not cause hepatitis B, HBV is a small, enveloped DNA virus known for its ability to persist in the body, sometimes leading to chronic hepatitis and long-term complications.
The most tried medicine for the AIDS virus is [A] Zidovudine (AZT). Developed in the 1980s, AZT was one of the first antiretroviral drugs approved for HIV/AIDS treatment.

The most tried medicine for the AIDS virus is [A] Zidovudine (AZT). Developed in the 1980s, AZT was one of the first antiretroviral drugs approved for HIV/AIDS treatment. It works by inhibiting the activity of the enzyme reverse transcriptase, essential for HIV replication. AZT has been a cornerstone of antiretroviral therapy (ART) regimens, helping to reduce viral load, improve immune function, and prolong the lives of individuals with HIV/AIDS. Nonoxinol-9 [C] is a spermicide, Miconazole [B] is an antifungal, and Virazole [D] is primarily used to treat respiratory syncytial virus (RSV) infections, unrelated to HIV/AIDS treatment.
The pressure exerted by a gas in a container is caused by the collisions of gas particles with the walls of the container. Gas particles move randomly and rapidly due to their kinetic energy. As they move, they frequently collide with the walls of the container, transferring momentum and exerting foRead more
The pressure exerted by a gas in a container is caused by the collisions of gas particles with the walls of the container. Gas particles move randomly and rapidly due to their kinetic energy. As they move, they frequently collide with the walls of the container, transferring momentum and exerting force on the walls.
The pressure is the result of the cumulative effect of all these collisions distributed over the surface area of the container’s walls. The speed and number of collisions depend on factors such as temperature and the amount of gas in the container. According to the ideal gas law (PV = nRT), an increase in temperature leads to faster particle motion and more frequent collisions, resulting in higher pressure. The pressure of a gas is thus determined by the intensity and frequency of particle collisions with the container walls.
The concept of diffusion explains the spread of smells in a room as the movement of gas particles from an area of higher concentration to an area of lower concentration. When a scented substance is released in a room, the odor molecules are initially concentrated around the source. Due to their kineRead more
The concept of diffusion explains the spread of smells in a room as the movement of gas particles from an area of higher concentration to an area of lower concentration. When a scented substance is released in a room, the odor molecules are initially concentrated around the source. Due to their kinetic energy, these gas particles move randomly and collide with air molecules.
As the odor molecules diffuse through the air, they spread out and gradually mix with other gases in the room. This process continues until the odor is evenly distributed throughout the space. Diffusion allows the scent molecules to travel from one end of the room to another, reaching individuals located far from the source of the smell. This natural tendency of molecules to disperse uniformly explains how smells quickly and efficiently spread across a room.
