What are the functions of the three types of openings in the model: openings in villi, alveoli, and the cell membrane?

Answers

Answer: These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body.

The process of exchanging gases (carbon dioxide for oxygen) occurs at the lung alveoli. Alveoli are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries.

In exocytosis, a cell releases substances into its environment. During exocytosis, vesicles that contain substances are moved to the cell membrane and fuse with it. This cell membrane function has three results: the total surface of the membrane increases, toxins or waste products are eliminated, and proteins become part of the plasma membrane.

Answer:

how do the conductivities of solutions of ionic compounds and covalent compounds compare

Answers

Answer:

Ionic compounds are hard and crystal-like, while covalent compounds are softer and more flexible.

Explanation:

Ionic compounds are also more soluble in water than covalent compounds. This is because water dissolves polar substances, which is the consistency of the ionic compound, whereas covalent compounds are non-polar.

Hope this helps

If not... tell me

ionic bonding happens when a metal gives a nonmetal one or more electrons to fufill the octet rule. covalent bonding happens when 2 or more nonmetals share 1 or more electrons to fufill the octet rule.
