The bones in the human body provides structure.
Answer:
Answer is below with the steps in order
Explanation:
4) Blood picks up carbon dioxide from the body
7) Heart pumps carbon dioxide rich blood to the lungs
8) Inhale
9) Nose traps germs in air
10) Air moves down the trachea
3) Air moves through bronchi into the bronchioles
6) Alveoli receive oxygen pass to blood
9) Oxygen passes into the blood
11) Alveoli receives carbon dioxide from the blood
12) Oxygen-rcih blood flows to the heart
3) Carbon Dioxide moves from bonchioles to bronchi
13)Carbon dioxide flows up
1) Heart pumps oxygen-rich blood to the body
The last <em>four of five</em> steps could be switched up a little bit since it all happens synchronously, but this is the most accurate interpretation.
The atomic number is the number of protons, while the atomic mass is the number of protons added to the number of neutrons. By definition, potassium (K) has atomic number 19, so it should have 19 protons. If it has a mass of 42, then the number of neutrons is 42 - 19 = 23 neutrons. This is choice (1).
The answer is 0.
n is the principal quantum number and l is the angular momentum quantum number. The possible values of ml (magnetic quantum number) range from -l to +l. In this case, 0 is the only possible value of ml.
But, as a further example, if n=2 and l=1, the possible values of ml would be -1, 0, and +1.
I think its A: 6-alkane or D:
