Digestion of which nutrient begins in the mouth?
Bonus: if you can name the process

Fact or Fiction, the 2,000 calorie diet is backed by science and the recommended daily amount for everyone.
Fiction!
2,000 calories was a "nice round number" that is not based on hard scientific data.
Each individuals daily caloric needs are different due to age, height, BMR and other factors.
(It's still an "OK" approximation though..)

You take a bite of a grilled cheese sandwich, describe in as much detail as possible where and how your body digests and absorbs each component (the bread and cheese) of your sandwich.
Your teeth grind the sandwich into smaller pieces (mechanical digestion). The salivary amylase in your saliva begins to breakdown the starch in the bread. You swallow and the bolus (chewed food passes through your esophagus to your stomach.
Your stomach uses mechanical digestion and chemical digestion to breakd the food down futher. Lactase breaks the lactose sugars in the cheese into glucose and galactose. Maltase breakds down the maltose sugar from the bread into two glucose sugars. The proteins in the cheese get broken down in the stomach as well.
The nutrients pass into the small intestine where bile (from the liver and pancrease) breaks down the fat in the cheese into fatty acids. The glucose, amino acids and triglycerides/fatty acids pass through the membrane of the villi in the small intestines and into the bloodstream (sugars and amino acids) and lymphatic system (fats).
The circulatory system carries the nutrients in the blood through arteries to capliaries to cells in the tissues. The nutrients enter into the cells and into the mitochondria where they are used in cellular respiration.
waste from cellular respiration (CO2) is then removed and carried out of the cell into the capillaries, to the veins and back to heart, to the lungs where it is breathed out.
Solid waste from the small intestine moves to the large intestine, where more water is absorbed, and it is stored until it is time to be removed from the body.

Fact or Fiction?
Bananas are clones.
Fact!
The bananas we eat are all regrown from a single individual!
This is done by taking a cutting of the young stem of a banana plant and replanting it, which eventually gives rise to a whole new banana plant. Because the new plants aren't grown from a fertilized seed, each banana plant therefore contains exactly the same genes as their 'parent' plant.
