According to the opponent process theory cells that are stimulated by exposure to yellow; light are inhibited by exposure to blue light.
Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.
Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.
Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.
Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
Answer: The correct answer is- Archaea and Eukarya.
As per the information about the (phylogenetic tree) given in the question,
the last branch of the phylogenetic tree begins with the line of Eukarya and then holds the species of the Archaea division, which includes those prokaryotic organisms that live in extremely harsh environmental conditions ( such as Methanobacterium, and extreme halophiles).
As this last branch holds species of two domains ( from 3 domain system of classification that includes Bacteria, Archaea, and Eukarya) , which are Archaea and Eukarya as it begins with Eukarya and later on holds the species of Archaea.
Thus, it shows that Archaea and Eukarya are more genetically related.
