Candy Chromatography By: Avani Reddy 7th Grade Introduction Ever wondered why candies are different colors? Ever wondered why candies are different colors? Many candies contain colored dyes. Bags of M&Ms or Skittles contain candies of various colors. The labels tell us the names of the dyes used in the candies. But which dyes are used in which candies? We can answer this by dissolving the dyes out of the candies and separating them using a method called chromatography. Research

the symptoms will be immediate. Herniated disks can occur anywhere along the spinal column‚ from the neck to the middle back to the lower back‚ though the lower back has the most frequent occurrences. Fortunately‚ most problems that occur with a ruptured disk can be corrected without surgery. In most cases‚ the cause of a herniated disk is the result of strenuous physical activity that involves the spinal column or the back. They can range from playing sports‚ twisting the body or lifting heavy

Arthritis Arthritis is an inflammatory condition that affects your joints‚ such as the knees‚ or a portion of your spinal column. Typical symptoms of this condition include joint pain‚ swelling and stiffness accompanied by a reduction in the ability to freely move your joints. Osteoarthritis and rheumatoid arthritis are the most common types of this disease. Bone Cancer

cartilage‚ the vomer‚ the inferior nasal conchae and the perpendicular plate. Question D: How would Hassan and his team be able to tell the ages of the skeletal remains of the woman and the baby? Answer: Age can be estimated by examining the vertebral column. Average length for an adult female is around 24 inches; in an adult male it is approximately 28 inches. The total number of vertebrae can also help determine age. During early development there are 33 total vertebrae. This number decreases as

posture can help with respiration and circulation. Most people’s postures aren’t perfect‚ but there are some extreme cases which are referred to as postural faults. Lordosis is used to describe an inward curve or arch to the lumbar and cervical columns of the vertebrae. A major factor of Lordosis is also that the pelvis tilts forwards and rests on the femurs. An increase in Lordosis can occur during puberty‚ but there are other causes such as imbalances in muscle strength and a difference in the

The features that the larger skeletal in the sarcophagus would show to indicate it was a female is the vertebral column of a female is about 61cm (24in.) and a male vertebral column of a male is about 71cm (28in.). F. The bone of the neck region that could be affected or damage by strangulation or neck trauma other than the cervical vertebrae is the hyoid bone. G. If the bones of a person

sclerotome of the somite create the mesenchymal cells in three major areas including the body wall‚ in the notochord and adjacent the neural tube (Christ & Wilting‚ 1992). The cartilaginous stage is the second phase of the embryology of the vertebrae column‚ which takes place during the sixth week. At this stage‚ a cartilaginous centrum is created through the fusion of two centers in evert centrum. Also‚ there is a fusion between the centrum and centers found in the vertebral arches (Kaplan‚ Spivak‚
