In the united states, tuberculosis is increasing in frequency due to homelessness and other diseases.
Tuberculosis (TB) is a bacterial infection spread through inhaling tiny droplets from the coughs or sneezes of an infected person. It mainly affects the lungs, but it can affect any part of the body, including the tummy (abdomen), glands, bones and nervous system.
TB is a potentially serious condition, but it can be cured if it's treated with the right antibiotics.
Typical symptoms of TB include:
- a persistent cough that lasts more than 3 weeks and usually brings up phlegm, which may be bloody
- weight loss
- night sweats
- high temperature
- tiredness and fatigue
- loss of appetite
- swellings in the neck
TB that affects the lungs (pulmonary TB) is the most contagious type, but it usually only spreads after prolonged exposure to someone with the illness. In most healthy people, the body's natural defence against infection and illness (the immune system) kills the bacteria and there are no symptoms.
Sometimes the immune system cannot kill the bacteria, but manages to prevent it spreading in the body. You will not have any symptoms, but the bacteria will remain in your body. This is known as latent TB. People with latent TB are not infectious to others.
If the immune system fails to kill or contain the infection, it can spread within the lungs or other parts of the body and symptoms will develop within a few weeks or months. This is known as active TB.

Oxigen ,nitrogen ,carbon,and hydrogen.
I believe the answer is B,( Allowing specific substances to flow into the cell).
Membrane protein is found in all types of cell membrane, it can either be integral protein, which is embedded within the membrane or associated protein, which is associated with the surface of cell membrane of phospholipid bilayer.
It performs several functions such as cell to cell communication, molecular transport and cell signaling.
Embedded proteins are proteins which are found in the cell membrane, which are completely embedded in the bilayer membrane of the cell membrane. It consists of hydrophilic head and hydrophobic tail. The head face towards the water molecule and tail face inward away from the water molecule. These protein help in the movement of molecules in and out of the membrane.
Example of embedded proteins: Channel proteins and carrier proteins and are example of some of the embedded proteins.
I apologize if this is not what you meant.
