There are a couple of different types of white blood cells, but I am going to focus on T-cells, or lymphocytes. T-cells are shaped like a sphere with spikes sticking out called T-cell receptors. They are produced in bone marrow and then are transported to the thymus (located under the breastbone). There are two kinds of T-cells; killer (which attack infested cells), and helper (which help with "coordinating" the attack). A T-cell only has a nucleus and no other organelles. As I said before, T-cells specialize in attacking infected cells. They release a toxin called cytotoxin which will kill the infected cell. T-cells are a part of the connective tissue, specifically the blood and bone part.

Sweetness Lab
In this lab, we tasted 8 different types of carbohydrates. The carbohydrates that had less structure were more sweet. The monosaccharides were super sweet such as glucose and fructose but the polysaccharides such as starch and cellulose were not sweet at all. Starch is found in breads and potatoes and it is the most common carbohydrate in the human diet. Milk has lactose in it which is a disaccharide. Fructose is extremely sweet, found in honey and fruits and is derived from sugar cane. Our tongues can differentiate between flavors such as sweetness because they have taste buds inside of the little bumps all over your tongue. Everybody's taste buds are different though and someone might think something is sweeter than what another person might think.
