Lungs in humans and many other species branch out into many tubes until they end in small sacks called alveoli. These alveoli al

low oxygen to enter the blood through the capillary beds as pictured above. Alveoli provide much more surface area for the lungs to contact the capillary beds. What is the advantage of lungs with alveoli compared to lungs without alveoli?

Answer:

It provides more surface area for the absorption of oxygen.

Explanation:

The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.

Polypeptides in the er are usually larger than polypeptides synthesized from the same mrna that have not entered the er.
olya-2409 [2.1K]

The statement 'polypeptides in the ER are usually larger than polypeptides synthesized from the same mRNA that have not entered the ER' is false.

The rough endoplasmic reticulum is the site where polypeptides enter so that protein formation can take place. Apart from protein formation, polypeptides are needed for various other metabolic functions by the ER.

Those polypeptides that are smaller in size can enter the endoplasmic reticulum because of the entering space and the small size of the endoplasmic reticulum. On the other hand, the polypeptides that are large, although being synthesized from the same mRNA, stay outside as they cannot enter the ER due to their large size.
