Search I’m safari there is the answer I think
Answer:
Explanation:
A cell is adapted to its function because of differential expression of genes during fetal development during which they get differentiated and determined to provide division of labour to different tissues. They contain protein fibres that can contract when energy is available, making the cells shorter.
1. Metals are the best conductors because their electrons run freely (Copper, gold, silver...) .
2. Nonmetals are insulators because they have a tight hold on their electrons (Glass, plastic, wood...).
Answer:
6,500 mL
Explanation:
We are asked to find the total volume of air that effectively entered to the alveoli in one minute so that oxygen could be exchanged for carbon dioxide and leave the body through exhalation.
The problem says that the normal breathing rate is 10 breaths per minute, and for each breathe it takes 800 mL of air. But not all air enters the alveoli because it says there are 150 mL that are not effectively used by the alveoli. Therefore, the net amount of air used in each breathe is 800 ml - 150mL, giving us a total amount of 650 mL of air.
Now that we have the net amount of air for each breathe, we have to multiply it by the total breaths a body makes in one minute. In this case, the breathing rate is 10 breaths/min.
So, to obtain the final answer we just need to multiply the amount of net air per breathe (650 mL) times the number of breathes in one minute (10 breathes); that is 650 mL/breath x 10 breaths and gives us 6,500 mL.
The cell membrane. it protects the cell from outside substances. it controls what can enter and leave the cell.
