The ductless gland system influences metabolic activity by means of hormones. endocrine organs and glands affect every body system, including the generative system. The procreative system functions to produce offspring. The female reproductive system does non function by dint ofout a womans undefiled life. When a womans reproductive system is no longer functional it is known as menopause. Menopause is a condition of the female reproductive system that is directly connected to the endocrine system.
Menopause is the absence of menstrual periods for twelve nonparallel months. Menopause usually occurs between the get along withs of forty six and 50 four (Marieb, E. N., & Hoehn, K. 2010). This is the time in a womans life when her ovaries cease to function as a reproductive organ. At this point, a woman is no longer productive because her ovaries are not producing eggs (Conrad Stöppler, M. 1996-2010).

Double Displacement

Bailey Klassen
Laura Doerksen
Period 2
April 18th, 2011
Introduction:

During this lab, the main type of reply was double displacement which is the molecular process involving the exchange of bonds mingled with the two reacting chemical substance species. This results in the creation of products with similar or identical bonding links. This type of reactions is known as a chemical reaction which is a process that leads to the trans governing body of unrivalled set of chemical substances to another. Other examples of chemical reactions include; mavin displacement, synthesis, decomposition and combustion. In this lab we could also observe the solvability of substances. Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a liquid dissolvent to form a homogenous solution. A helpful shit habitd to determine the solvability of a substance is the solubility chart. This chart contains a list of ions and how, when mixed with other ions, they apprise become precipitates or remain aqueous. In other words, it shows the solubility of various compounds.

Human Digestion

Human Digestion

The digestive process begins as soon as food enters the mouth. Saliva begins to immediately abound down sugars and starches, epoch the teeth grind down the food. Food then enters the defile and is swallowed, where it then enters the stomach for further breakdown by mode of stomach acids. Very little of the food is actually digested in the stomach. Instead, the acids work to break down the food for easier digestion in the intestines. As the food is broken down to a thick paste-like depicted object known as chyme, it moves past the pyloric sphincter and into the bantam intestine. The first section of the small intestine, the duodenum, secretes digestive enzymes like amylase, maltase, sucrase, lactase, lipase and pepsin, to break down the chyme into even smaller parts that the body corporation then convert into usable energy. Some other organs that secrete chemicals to aid in the digestion process include the pancreas, liver, and freshness bladder. The pancreas secretes trypsin and chymotripsin. The liver and gall bladder secrete bile, used for the emulsification of fats. The bit section of the small intestine, the jejunum, is where the majority of food is absorbed into the bloodstream. The terminal section of the small intestine, the ileum, is where the remainder of nutrients is absorbed.

What is non absorbed by the small intestine passes into the large intestine, which includes the colon and rectum.

The colon absorbs water, vitamins and minerals not absorbed by the small intestine.

Chemical Formula

Define Chemical conventionality.

A chemical formula or molecular formula is a way of expressing data close to the atoms that constitute a particular chemical compound.
The chemical formula identifies for each star constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule of that compound. If a molecule contains more(prenominal) than one atom of a particular element, this quantity is indicated using a subscript after the chemical symbol (although 18th-century books often apply superscripts) and also can be combined by more chemical elements. For example, methane, a small molecule consisting of one deoxycytidine monophosphate atom and four hydrogen atoms, has the chemical formula CH4. The simoleons molecule glucose has cardinal carbon atoms, twelve hydrogen atoms and six oxygen atoms, so its chemical formula is C6H12O6.
Chemical formulas whitethorn be used in chemical equations to describe chemical reactions. For ionic compounds and other non-molecular substances an empirical formula may be used, in which the subscripts indicate the ratio of the elements.
The 19th-century Swedish chemist Jöns Jacob Berzelius worked out this system for writing chemical formulas.

Frequently, acne appears on the face, neck, chest, back, and upper arms of the human body. Acne is formed by obturate pores on the human skin. Pores could get blocked due to oil, stone-dead skin cells, and bacteria. Blocked pores create an ideal environment for a bacterium called Propionibacterium to flourish, which eventually leads to blackheads or whiteheads.

Lesson 6 - The Cardio-Respiratory System
DefinitionsThe cardio-respiratory system consists of the cardio vascular system ( nubble and blood vessels) in concert with respiratory system (lungs and product line ways). These systems work to transport group O to the muscles and organs of the body and remove waste products including carbon dioxide. The HeartThe boob is a double pump. oxygen- paltry blood enters the tone from the vena cava to the near atrium, and flows down to the right ventricle. The first pump pumps oxygen poor blood to the lungs from the right ventricle of the heart via the pulmonary arteria where it returns as oxygen rich blood via the pulmonary mineral vein to the left atrium. It flows through to the left ventricle, where the second pump of the heart pumps the oxygen-rich blood to all the other parts of the body, via the aorta. There argon four valves that ensure blood flows in the correct direction, these atomic number 18 the pulmonary valve, the tricuspid valve, the mitral valve and the aortic valve. | |

Ben and William Franklin

Ben and William Franklin were masters at the art of compromise. They used compromise in their world and personal life to create influence and successfulness for themselves. But as the conflicts between England and the American Colonies increased in the middle eighteenth century, and the rift between the loyalists and patriots became more defined, two start out and son found themselves having to choose distinct sides where their coarse mode of compromise could not be kept intact. As it would be, father and son chose opposite sides of the conflict. Due to this, by examining the disruption of Ben and William Franklins nature to compromise in their dealings as public figures, a clear parallel can be seen with that of the partitioning in their private lives as father and son.

Early on, Ben Franklin power saw the benefit of compromise. As a lover of discourse, Franklin soon espouse a style of address that was drastically different than that of his eldest style as the emphatic debater. (Autobiography 20) After he had switched his speaking style to that of the Socratic method, he eventually loosened his elbow room to expressing myself in terms of modest diffidence (Autobiography 25) Even his newspaper, The dad Gazette, was run on his philosophy of compromise so that it erupt no one (Skemp 12).

William, had learned his first and most enduring political lessons at his fathers knee (Skemp 88) and doubtless, the clever conversational and compromising tactics of his father had an impacting influence upon the younger Franklin. Bens involvement and influence truly helped shape Williams public, as well as his private, life. Indeed, it was due to his fathers encouragement that William enlisted in the Royal Army, studied law, and was justified in accepting governorship of parvenue Jersey.

U ltra V iolet Light Rays
Ultraviolet (UV) rays are hidden rays that are part of the energy that comes from the sun. UV rays can evoke the looks, hair, and genuflect if these parts of the body are not decently saved.
Sunlight contains three types of ultraviolet rays: UVA, UVB, and UVC.
* UVA rays cause unclothe develop and wrinkling, and contribute to skin cancer,
* UVB rays are also dangerous, causing sunburns, cataracts (clouding of the kernel lens), immune system damage, and contributing to skin cancer. 
*UVC rays are the to the highest degree dangerous, but fortunately, these rays are blocked by the ozone layer and dont pee the earth.
2/ Effects of sunglight:
Sunburn : A sunburn develops when the bar of UV exposure is greater than what can be protected against by the skins melanin.  
Skin Cancer: Exposure to UV radiation appears to be the most important environmental factor in the development of skin cancer.  Scientists believe that the increase in skin cancer has resulted from:
* Increased outdoor time.
* Decrease in the measuring rod of clothing worn outdoors.
* Decrease in atmospheric ozone levels.
plaza Damage: UV radiation that can damage tissues of the eye.

  Results scientist call down that spending long hours in the sun without eye shelter increases the chances of developing eye diseases, including cataracts. Cataracts are a form of eye damage that causes the loss of transparency in the lens, clouding vision.
age/Wrinkling: When UV rays reach your skin, they interact with a natural chemical substance in the skin called melanin and can lead to various forms of skin damage including aging and wrinkles.
