Answer:
the answer is a prokaryotic cell
Answer:
B) increased exchange surface provided by their membranes
Explanation:
Alveoli are tiny air sacs that are responsible for exchanging oxygen (O2) and carbon dioxide (CO2) in the lungs. Alveoli have elastic fibers in order to expand and recoil depending on the volume of air breathed in. The alveolar epithelial cells (pneumocytes) may adopt a shape that serves to increase the surface area of gas exchange. On the other hand, intestinal epithelial cells have microvilli, which are microscopic projections in the plasma membrane. Microvilli serve to increase the cell's surface area, thereby facilitating the absorption of nutrients and water.
Answer:
B. it relaxes
Explanation:
Antagonisms. one muscle contract while the opposite one relaxes to carry out an action.
The answers are "<span>gravitational, electric, and magnetic fields." When too electrons rub against each other that creates a electric field. Electrons often stick together which causes a gravitational, and sometimes magnetic fields.
