Answer: The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to pass easily down this gradient due to the alveoli having very thin walls (one cell thick).
or
The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick)
Hope this helps......... Stay safe and have a Merry Christmas!!!!!!!!!!! :D
Explanation:
Because of its rotation, the inner core of Earth is the cause of its magnetic field. This magnetic field helps protect the surface of the Earth from cosmic rays and other space-related particles. Human life could never have developed without this protection. The heat also accounts for most of the geological activity on Earth, including continent drift, and the magma associated with volcanic activity.

Answer:
Cytoskeleton
Explanation:
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement. Cytoskeleton is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition including microtubules, actin filaments and intermediate filaments.
