If you wanted to see a cell wall, where could you look?.
tatyana61 [14]

Answer:

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Umnica [9.8K]

Answer: All of the above.

Explanation:

The liver is simply the largest solid organ in the body and it can be found below the rib cage in the upper abdomen by the right. It's function is to maintain the blood sugar, regulate blood clotting and remove toxins from the blood.

It should be noted that the liver develops as a ventral outgrowth of the embryonic foregut. It also helps in the incorporation of both the endodermal and the mesodermal components. Furthermore, it's developed in the ventral mesentery and is connected to the stomach by the lesser omentum.

Therefore, all of the above options are correct.
