A.
Commuters drive personal vehicles to their places of work: offices, manufacturing plants etc.

Some may use car pooling or mass transit like buses. But too many want the luxury and convenience of coming and going on their own terms.

IMHO car pooling and mass transit needs to be used more to reduce environmental harm.

Answer:

muscles

ribs

lungs

bronchioles

alveoli

diffuses

leaves

exchange

Explanation:

Your diaphragm, and <u>muscles</u> between your <u>ribs</u>, make air move in and out of your <u>lungs</u>. It travels through the trachea, bronchi, and <u>bronchioles </u>to <u>alveoli</u>. In the alveoli, oxygen <u>diffuses</u> into the blood and carbon dioxide<u> leaves</u>. This is gas <u>exchange</u>.

<em>Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.</em>

Because some plant groups readily hybridize with other plant groups, which species conceptis not very useful in defining plant s
Leviafan [203]

Interbreeding species concept-species concepts is not very useful in defining plant species because some plant groups readily hybridize with other plant groups. The biological species concept holds that organisms are members of a common species if they can interbreed and result in live, fertile offspring. Prezygotic and postzygotic obstacles separate species from one another and prevent mating or the development of viable, fertile offspring. New species emerge through a process called speciation. It happens when populations of a species diverge and become reproductively isolated. When groups from an ancestral population undergo allopatric speciation, it is because of a period of geographic isolation that they diverge into distinct species. When groups from the same ancestral population evolve into distinct species, there is no geographical separation.
