Answer:
oxygen
Explanation:
oxygen is an essential nutrient which the body needs especially during respiration.
it help the blood cells do provide energy.
without oxygen, there is no gaseous exchange

ATP is the cell's energy, the mitochondria (aka the power house of the cell) is what produces ATP. The process is called Cellular Respiration.
The correct answer is Option B: 3%.
In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.
<h3>What is doubling time?</h3>
- The doubling time is the time taken by a population to double in its size.
- This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
- There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
- Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
- Here, Doubling time= 23.3 years.
- Growth rate= 70/23.3= 3%

Answer:
Vesículas e vacúolos são sacos ligados à membrana que funcionam no armazenamento e transporte. Os vacúolos são um pouco maiores do que as vesículas, e a membrana de um vacúolo não se funde com as membranas de outros componentes celulares. As vesículas podem se fundir com outras membranas dentro do sistema celular
