Answer: True
Explanation:
Tuberculosis(TB) is most common in developing countries where many people live in absolute poverty, than in developed countries.
In underdeveloped and developing countries people lack proper education on the spread of tuberculosis, they live and work in poorly ventilated and overcrowded conditions, which provide ideal conditions for TB bacteria to spread.
In developing countries where people have limited access to healthcare system, people with HIV who are more susceptible to TB, lack proper healthcare suffer from malnutrition and can't build a resistance to the disease. In this conditions TB is bound to spread.
Developed countries have largely controlled TB by improving the life of it citizens, provision of healthcare, education etc

Hey there!
Let's start with the first blank. The ozone layer starts in the stratosphere and is made of ozone gases made to protect the Earth from the Sun's harmful UV rays. If the ozone layer wasn't there (not to mention the rest of the atmosphere), we would be exposed to that kind of radiation. Thereofe, "Ultra violet rys would not be <u>blocked</u> by the ozone layer."
For the next one, a lot of levels of substances in the air would change, like UV and oxygen- as there would be more radiation from the lack of protection and all the oxygen would escape.
Hopefully this helps!
<u>Answer</u>: D. The inside of the cell becomes less negative in charge relative to the outside of the cell.
During depolarization, the membrane potential moves towards zero. This process is initiated by that enters the cell due to the polarization of the cell. Outside of the cell, the concentration of the positively charged sodium ion is higher by a factor of 10, compared with the interior of the cell. Due to the presence of the sodium cation in increasing amounts inside the cell, the relative voltage will change immediately. This will result in an interior of the cell that is less negative in charge relative to the outside of the cell.
