Neutrophil white blood cells

White blood cells are cells are highly specialized cells that help the body fight bacteria, and infections. They have several types, but the most common two are lymphocytes and neutrophils. The job of the neutrophils are to defend the body against any infections or bacteria. Even though they are found in the blood stream, it's mostly in the tissue where they fight bacteria and infections. White blood cells travel from the blood vessels, to the tissue that is infected. They have a nucleus and therefore can create their own protein and RNA. Having a low number of neutrophil white blood cells in a body greatly increases the chance of a bacterial infection.

A&P Sweetness Lab

Today we tasted  and ranked eight different sugars for their sweetness. The sugars all looked the same except maltose, but they all had unique tastes. It turns out that the more rings that a sugar has, the less sweet it tastes. Starch and cellulose which both have several hundred rings tasted more bland and received 0/200 and 25/200 respectively. On the other hand fructose and glucose which were ranked the sweetest, had very few rings. Other sugars tasted like the foods that they were in, such as lactose and fructose. In my mouth, lactose tasted like dry milk, and fructose tasted as sweet as fruit. 

We can distinguish between different tastes, because of chemical reactions with the proteins and taste buds. The taste buds are then able to connect with the brain which connects what we are tasting.
