<span>Diffusion. Diffusion is when particles in a highly concentrated area spread out to an area of lower concentration. The membranes of cells are very thin, which allows diffusion of different materials to happen easily.
During respiration, oxygen and glucose concentration in the cell is lower than in the surrounding blood. This causes oxygen and glucose to move into the cell via diffusion. Carbon dioxide is produced inside the cell and this makes the concentration of CO2 higher in the cell than in the blood, so the excess diffuses out of the cell.</span>
Prokaryotes are single celled organism that lacks a membrane bound nucleus, mitochondria, or any other membrane bound organelle. Examples of prokaryotes include all single-celled organisms, most of which are bacteria. The principle ecological role of prokaryotes is to break down organic matter.
"<span>Based on variability, the costs has been classified into three categories, they are fixed, variable and semi variable. </span>Fixed costs<span>, as its name suggests, is fixed in total i.e. irrespective of the number of output produced. </span>Variable costs<span> vary with the number of output produced. </span>Semi-variable<span> is the type of costs, which have the characteristics of both fixed costs and variable costs".</span><span>

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.
