Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Most of the digestion and absorption in the small intestine is accomplished by the duodenum; the longest portion of the small intestine is the ileum.
<h3>What is Digestion and Absorption?</h3>
Digestion stands for the complex function of turning the food you eat into nutrients, which the body utilizes for energy, growth, and cell repair required to survive. The digestion process also concerns creating waste to be eliminated.
Digestion stands for the breakdown of extensive insoluble food molecules into small water-soluble food molecules so that they can be immersed in the watery blood plasma. In particular organisms, these smaller substances exist absorbed via the small intestine into the bloodstream.
Absorption exists as a physical or chemical phenomenon or a procedure in which atoms, molecules, or ions penetrate some bulk phase – liquid or solid material. This is a separate process from adsorption since molecules undergoing absorption stand taken up by the volume, not by the surface.
