The Shrek Franchise From princesses to pirates, Disney seems to portray every role imaginable and that would include a green ogre and a foul mouthed donkey. Shrek was first released in May of 2001. Produced and distributed by DreamWorks, Shrek was made with a 60 million dollar budget. At the end of Shrek’s reign at the box office, it had raked in 484.4 million dollars worldwide but that was just the start of the franchise. Shrek 2 (2004), Shrek the Third (2007), and Shrek Forever After (2010) were produced along with spin-offs such as Puss and Boots (2011). All in all, the Shrek franchise has raked in 3.5 billion dollars at the box office alone. What made Shrek so popular has been its ability to cater to young and adult audiences. Shrek features childish and whimsical humor and also crude adult humor. Also, Shrek makes several cultural references to other Disney movies such as Snow White and the Seven Dwarves, Tinkerbell, The Three Little Pigs, Peter Pan, and many more. These references introduce the younger audience to more Disney franchises while providing nostalgia for older viewers. Shrek also features new age pop music such as “All Star” by Smash Mouth and oldies like “Try a Little Tenderness.” Marketing for Shrek started shortly before the movie’s release date in May, Burger King promoted Shrek with character shaped candies that would be included in kid meals. Baskin Robbins sold Shrek themed ice cream. Shortly after the major success of Shrek, Disney began to strike up licensing deals to sell Shrek products. Clothing manufacturers began to create Shrek themed clothing, toy companies such as Hasbro began to produce Shrek toys, and Conagra Foods, owners of Kid Cuisine, began to incorporate Shrek into foods. After each Shrek movie, the sells of Shrek merchandise skyrocketed which produced billions of dollars in revenue for Disney. The products were mainly targeted towards children and priced reasonably to ensure more sells. Shrek would be further promoted in publications such as Rolling Stone magazine and Entertainment Weekly and this fueled the Shrek mania. Many video games were produced following the release of Shrek such as Shrek: Hassle at The Castle and Shrek 2: The Game. In 2006, the total combined sales of Shrek console games reached 2.5 million units. All in all, the Shrek franchise has been and will continue to be successful.

Question:

In your own words, list and briefly describe the importance of the 11 major organ systems in the human body.

1. Integumentary system: This system is what envelopes the human body. The integumentary system is comprised of the hair, skin, and nails, and it houses the many sensory receptors that perceive pressure, heat, cold, and other sensations. 2. Reproductive system (male and female): The reproductive system is composed of two sets of organs: primary and secondary. The primary organs are referred to as the gonads which are the ovaries and testes. These organs are responsible for the production of gametes, the sperm cells found in the testes and the eggs found in the ovaries, and hormones such as testosterone and estrogen. The secondary organs include everything else that would be associated with the primary organs. For example: the uterus is a secondary sex organ in females, and the penis is a secondary sex organ in men. 3. Lymphatic system: The lymphatic system is composed of the spleen, lymph nodes, lymphatic vessels that move lymph fluid throughout the body, and thymus. This system is primary in protection against infections and rids the body of harmful pathogens. 4. Skeletal system: The skeletal system is comprised of cartilage and bone that provide support for the organs and human body. On average, the adult human body has 206 bones. The skeletal system also houses the hematopoietic system which creates red blood cells, most of the white blood cells found in the blood, and platelets. 5. Endocrine system: This system is comprised of many organs that are responsible for regulating body functions such as heart rate, temperature, blood pressure, electrolyte balance, and other functions to maintain homeostasis which means to maintain a stable equilibrium. The endocrine system is composed of the pituitary gland, thyroid gland, adrenal glands, primary sex organs, and the pancreas, and they all release hormones to help control bodily functions. 6. Respiratory System: The respiratory system is made up of the nasal passages, trachea, lungs, and assistive organs such as the diaphragm. The respiratory system is responsible for the inhalation and exhalation of air into and out of the lungs. In the lungs, a switch is made between the oxygen and carbon dioxide molecules in the alveoli sacs. This is where red blood cells become oxygenated and carbon dioxide is expelled from the body. 7. Cardiovascular system: This is also known as the circulatory system, which is comprised of the heart, arteries, veins, and the lymphatic system. The circulatory system is responsible for moving blood and lymph fluid throughout the body to provide nutrients and oxygen and to fight against invading foreign bodies such as bacteria and viruses. 8. Digestive system: The digestive system is comprised of the stomach, liver, pancreas, gall bladder, and the small and large intestines. The digestive system primarily functions to break down the food we eat into smaller portions so that it can be better absorbed by the intestines. From there, we move to the excretory system which removes waste from the body and undigested food. 9. Urinary system: The urinary system is involved in the removal or the retention of fluid in the body. Blood passes through the kidneys and enters glomerular filtration where the blood is purged of waste and impurities. The amount of fluid that is removed from the body is dependent upon the endocrine system. The three main hormones that influence the balance of fluid and electrolytes in the body are: antidiuretic hormone (ADH), aldosterone, and atrial natriuretic hormone (ANH). ADH is produced in the posterior portion of the pituitary gland and causes the kidneys to reabsorb water rather than have it expelled from the body as urine. Aldosterone is produced in the adrenal glands and promotes the reabsorption of sodium rather than it be lost when urinating. ANH is produced by the atrium of the heart and causes the excretion of sodium. 10. Muscular system: The muscular system is comprised of three main types of muscle: smooth (involuntary) muscles, striated skeletal muscle (voluntary), and striated cardiac muscle which is involuntary but controlled by both involuntary and voluntary actions. Smooth muscle is incapable of being controlled of by the conscious mind. An example of smooth muscle would be the intestines creating wave like motions (peristalsis) to move food through the digestive system and out the excretory system. Skeletal muscle is voluntary because it can be moved by conscious thought. For example, when someone raises their arm or kicks their leg. The striations in skeletal muscle are apparent along skeletal muscles because of sarcomeres which are the basic functional units of skeletal muscle. Also, skeletal muscle is multinucleated. Cardiac muscle is both striated and involuntary which makes it unique. Cardiac muscle cannot be controlled by conscious thought, but it is controlled by the sinus node which conducts an electrical pulse that causes the heart to pump. The rate at which the heart pumps is controlled by physical movement and hormones, such as adrenaline, produced in the body. 11. Nervous system: This system is the most complex system in the human body. It is comprised of the brain, spinal cord, and several nerves that run throughout the body. The nervous system is also broken up into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of motor and sensory nerves. Motor, or efferent, nerves are responsible for the transmission of signals from the brain to the motor neurons to the body to perform an action. Sensory, or afferent, nerves are responsible for sending signals back to the brain from sensory receptors located throughout the body. For example, a sensory neuron will send a signal to the brain if you are touching something hot. The PNS is composed of the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is activated when the body is in danger and in emergency situations. This system is also referred to as "flight or fight." The parasympathetic nervous system is responsible for the feeling of needing to rest or sleep, hunger, and sexual arousal.

Question:

Find (x) using both factoring and the quadratic formula: x$$^{2}$$ + 5x - 6

Inactive
Elijah W.

To begin, we will solve by factoring or determine if the expression can be factored in this format. If the original expression can not be factored, perfect square factorization may need to be utilized. Firstly, we must identify the numbers and signs of importance, which are the middle and last term, and find which numbers will multiply together that equal the sign and number of the last term of the expression. To do this, we have to find the factors of 6 which are: 1, 2, 3, and 6. From there, we must determine which factors of 6 can be multiplied together to equal negative 6. To answer that, we must know the ways in which the product of aforementioned factors can be multiplied together to equal negative six. So, following the rules of multiplication, one factor must be positive and one factor must be negative in order to have a negative six. So, the multiplication of factors could be: (-1(6)), (1,(-6)), (-2,(3)), or (2(3)). Next, we must determine (when added together) if any of those products will create the sum of positive five. Looking at the factors, we can see that (-1(6)) will equal negative six and add together to equal positive 5. So, we would then know the factors of the expression are (x+6) and (x-1). Finally, we set the factors of the expression equal to zero and solve for x. $$x-1=0$$ $$x+6=0$$ $$x=1$$ $$x=-6$$ Next, we must find x by using the quadratic formula. The quadratic formula is: $$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$ The variable (a) is equal to the first term, the variable (b) is equal to the second term, and the variable (c) is equal to the third term. We would simply solve this by entering in the numbers. $$x=\frac{-5\pm\sqrt{5^2-4(1)(-6)}}{2(-6)}$$ We would then work out the formula for both the addition and subtraction of the square root. $$x=\frac{-5+\sqrt{5^2-4(1)(-6)}}{2(-6)}$$ and $$x=\frac{-5-\sqrt{5^2-4(1)(-6)}}{2(-6)}$$ Should the number under the square root found to be negative, we must reject using the quadratic formula for finding any real solutions for the expression since the square root of a negative number does not exist. We would only include those solutions when looking for imaginary solutions. After completing the mathematical steps to solve the above quadratic formulas, we find that $$x=-1$$ and $$x=6$$ are the real solutions to the expression.
