<span>In liver, the most intensively studied transmembrane and intracellular signal transduction pathways are the Janus kinase signal transduction pathway, the mitogen-activated protein kinases signal transduction pathway, the transforming growth factor β signal transduction pathway, the tumor necrosis factor α signal transduction pathway and the recently discovered sphingolipid signal transduction pathway. All of them are activated by many different cytokines and growth factors. They regulate specific cell mechanisms such as hepatocytes proliferation, growth, differentiation, adhesion, apoptosis, and synthesis and degradation of the extracellular matrix. The replication cycle of hepatitis C virus (HCV) is intracellular and requires signal </span>

if this is correct please give me Brainliest.
The answer would be bacteria and and fungi
I believe you're looking for the process of absorption.
In absorption, digested, simple and soluble food molecules is absorbed into the body through the wall of small intestine. They move by methods of diffusion and active transport.
Villi in the intestinal wall also helps the absorption process. Villi can provide a large surface area so that more food can be absorbed at the same time. Also, the network of blood capillaries can help maintain a steep concentration gradient so that food molecules can be absorbed faster.
Absorption process is the process after digestion. Followed by it, assimilation can help the food become part of the cells and get used.
