Gelatin Abstract: For this inquiry lab‚ the research team tested the gelatin solution for the presence of biomolecules. The team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein) reacted with the gelatin solution

in the neck as represented by the image below left. The causes of chronic hypothyroidism are fairly distinct. Around the world in third-world and developing countries‚ iodine deficiency is the most common cause of hypothyroidism. This used to be true as well for developed countries‚ but today this is a less common cause as iodine usually finds its way into our diets without too much trouble. In modern-day developed countries‚ hypothyroidism is mainly a result of Hashimoto’s thyroiditis‚ a birth defect

it may also be due to the invasion of the thyroid gland by the leukocytes‚ mainly the T-lymphocytes. It’s important to note that in patients who have this disease‚ iodine deficiency can still pose a real concern to healthy functioning of the thyroid gland. The world health organization says that the maximum tolerable intake for iodine is 1100mcg per day for pregnant women.

The endocrine system is a control system of ductless glands that secrete chemical "instant messengers" called hormones that circulate within the body via the bloodstream to affect distant cells within specific organs. Endocrine glands secrete their products immediately into the blood or interstitial fluid‚ without storage of the chemical. Hormones act as "messengers‚" and are carried by the bloodstream to different cells in the body‚ which interpret these messages and act on them. Typical endocrine

1.According to the kinetic theory‚ both the particles in gases and the particles in liquids have kinetic energy. This energy allows the particles in gases and liquids to flow past one another‚ as shown in Figure 13.5. Substances that can flow are referred to as fluids. The ability of gases and liquids to flow allows them to conform to the shape of their containers. Figure 13.5 Both liquids and gases can flow. The liquid on the left is colored water. The gas on the right is bromine vapor. If a
