Scientific Practices Follow the Hormone
Using the Internet as a resource, identify a hormone produced by a healthy thyroid and then find two roles it plays in the body. How does the hormone travel from the thyroid to those organs?
![Check Mark](/static/check-mark.png)
Interpretation:
A hormone produced by a healthy thyroid and its role in the body has to be identified. The way in which the hormone travels from thyroid to organs has to be determined.
Concept Introduction:
Hormones: Hormones are chemical messengers which are secreted by the cell in endocrine system and are transported along the blood to stimulate the target cells having the corresponding receptors.
Thyroxine molecule is nonpolar hormone produced by thyroid.
Explanation of Solution
An example for a hormone produced by a healthy thyroid is thyroxine. Thyroxine helps in regulating the rate of metabolism and in maintenance of the bones.
Thyroxine is a hormone and is secreted directly to the blood to reach the target organs.

Chemistry In Context
- Like anatomy and physiology, chemistry may be a somewhat scary subject for you. Think of it this way: Chemistry is simply the study of matter, its composition, structure, properties, and the changes matter may undergo. Your goal in training as a cosmetologist is not to become a scientist, but to develop a comfort level with the basics and an ability to discuss chemistry in relation to your profession. This will increase your credibility significantly with your clients, especially during the consultation process. In the space provided, write how chemistry affects your everyday life.arrow_forwardFor years we’ve been told that eating fat will cause various health problems and have been warned to eliminate it from our diet. But now we know that not all fat is the same. By understanding the difference between good and bad fats and how to include more healthy fat in your diet, you can improve your mood, boost your energy and well-being, and even lose weight. Since fat is an important part of a healthy diet, rather than adopting a low-fat diet, it’s more important to focus on eating more beneficial “good” fats and limiting harmful “bad” fats. What is their experience with the health risks associated with ‘bad fat’ intake for example obesity, diabetes, heart disease, strokes, cancer, etc.? Why is eating healthy so important?

- Write a paraphrase of the following passages.1. Bats are in the limelight these days because they are rumored to be the source of COVID-19, the virus that caused the coronavirus pandemic. But that is just part of their story. Bats turn out to be miraculous creatures. Their ability to age without decrepitude or cancer, as well as fight off a multitude of infections, are giving us clues about how to do the same for ourselves.arrow_forwardGive the functions of the following ingredients, then name a branded/commercial skin or hair care product where the said material is used.

This is quite impressive given that the atmosphere during Archaean and early Proterozoic times was largely devoid of oxygen! Therefore, this reflects the photosynthetic efficiency of the early biosphere, coupled with its operation over long periods of time. Knowing that the mass of the modern atmosphere is 5.01×1018 kg, of which 21% is oxygen, what is the mass (in kilograms) of oxygen contained within BIFS? 6.9 x 1016 kg of O2 contained in BIF deposits Knowing that the molecular mass of O2 is 32 g/mole (0.032 kg/mole), how many moles of O2 are contained within BIFS? 2.17 x 1018 moles of O2 contained in BIF deposits Now, let us think about iron (Fe). The total mass of BIF's globally is estimated at 5.0x1017 kg, wherein iron accounts for approximately 35% by mass. The atomic mass of iron is 55.8 g/mole (0.0558 kg/mole).
