Biology
1 answer:
borishaifa [10]3 years ago
7 0

Answer:

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Cells contain parts known as organelles. These parts are specialized. What does this mean?
navik [9.2K]
"Specialized" organelles or parts means that these parts have been modified to carry out a specific function that is unique to them. Organelles are literally "little organs" and each of them in the cell has a specific and distinct function. For example the nucleus is an organelle. It is arguably the most important organelle in the cell. Its specific overall function is that it acts as the cell control center, directing the activities of all the other organelles .i.e. what they need do and when to do it. The nucleus also contains all of the cell's genetic material (DNA).
