Answer: The hepatic portal vein is one of the most important vein that receives blood from the body and transports it into the liver for filtration and processing. This vein is part of the hepatic portal system that receives all of the blood draining from the abdominal digestive tract, as well as from the pancreas, gallbladder, and spleen.
‘Hepatic’ means of or relating to the liver, therefore the hepatic portal vein is a blood vessel that sends nutrient-rich blood from the gastrointestinal tract and spleen to the liver, but also delivers toxins to the liver that will be chemically modified in the proces of detoxication
In photosynthesis, carbon dioxide is reduced and H₂O is oxidized. The type of chemical reaction is an oxidation-reduction reaction.

Explanation
Oxidation-reduction reaction are reactions that take place in electrochemical processes. Reduction is the reaction of decreasing oxidation number and increasing electrons and it can be said that reduction is the reaction of a substance losing oxygen. Oxidation is the reaction of increasing the oxidation number and decreasing electrons and can be said that oxidation is a reaction where the reaction of a substance binds oxygen.
Photosynthesis is one type of oxidation-reduction reaction that occurs naturally in everyday life. Photosynthesis has a complex process and involves green plants and certain bacteria. In the event of photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized to oxygen.
The oxidation-reduction reaction in photosynthesis is:
6CO₂(g) + 6H₂O(l) + energy --> C₆H₁₂O₆(aq) + 6O₂(g)

A single gene could be inserted into a plant's genome, enabling specific traits to be expressed easily. Scientists have identified genes for two enzymes needed to make pro-vitamin A. One of these genes comes from corn.
Myosin and actin protein filaments attach to each other . Calcium ions release into myofibrilles . Myosin filaments pull on the actin filaments
