The process that requires energy for digested nutrients to pass through the small intestinal wall into the villi is called active transport
In the process of digestion, complex food molecules are broken down into macromolecules which are absorbed by the body. The absorption of nutrients such as glucose, vitamins, and amino acids takes place in the small intestine.
The small intestine contains tiny hair-like projections called the microvilli that are rich in blood vessels. These structures help in the absorption of nutrients.
As the concentration of these nutrients is higher in the bloodstream than in the intestine. The absorption of nutrients requires energy for the movement of nutrients from lower concentration to higher concentration. This energy-driven transportation is called active transport.

Presidential Reconstruction
In the spring of 1865, the Civil War came to an end, leaving over 620,000 dead and a devastating path of destruction throughout the south. The North now faced the task of reconstructing the ravaged and indignant Confederate states. There were many important questions that needed to be answered as the nation faced the challenges of peace:
<span>Who would direct the process of Reconstruction? The South itself, Congress, or the President?Should the Confederate leaders be tried for treason?How would the south, both physically and economically devastated, be rebuilt? And at whose expense?How would the south be readmitted and reintegrated into the Union?<span>What should be done with over four million freed slaves? Were they to be given land, social equality, education, and voting rights?</span></span>
For the answer to the question above, the best stage in fern life cycle is the sporophyte stage. It is the <span>multicellular diploid stage in the life cycle of a plant or <span>algae</span></span>.<span> Developing from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell, therefore, has a double set of chromosomes, one set from each of its parentchromosomes.</span>
Peritoneum or it could be gut organs
