sores‚ growths‚ etc. Skin cancer is a deadly disease with many causes‚ but the only advantage is that it can be prevented. Skin cancer is a disease where cancer (malignant) cells are found on the outer layer of the skin (epidermis). The three types of cells found in the epidermis are squamous cells‚ basal cells‚ and melanocytes. These cells in time grow to be cancerous. Thus‚ the three types of skin cancers are squamous cell‚ basal cell‚ and melanoma. Melanoma is the most deadly and destructive type

and little to none occurs in stems‚ etc. The parts of a typical leaf include the upper and lower epidermis‚ the mesophyll‚ the vascular bundle(s) (veins)‚ and the stomates. The upper and lower epidermal cells do not have chloroplasts‚ thus photosynthesis does not occur there. They serve primarily as protection for the rest of the leaf. The stomates are holes which occur primarily in the lower epidermis and are for air exchange: they let CO2 in and O2 out. The vascular bundles or veins in a leaf are

DNA SPOOLING ISOLATION OF DNA FROM ONION INTRODUCTION This project will demonstrate several basic steps required for isolation of chromosomal DNA from cells. To extract the chromosomal DNA‚ both the cell membrane and the nuclear membrane must be broken open. This is accomplished by disrupting the membranes with a solution of detergent and salt‚creating a cell homogenate. Once the DNA is released from the nucleus‚ it must be protected from nucleases‚ enzymes which will degrade the DNA. Keeping

According to the video‚ the skin is composed of three layers with each layer having different types of cells.

Ann Duffy’s ‘Valentine’ ultimately depicts a highly cynical attitude towards love and conventional gestures of affection. The poem uses traditional images of valentine as a starting point‚ before showing how an onion is much more true to the nature of love. An extended metaphor of the onion is then used to depict Duffy’s underlying implication that love can be destructive on many different levels. One of the main ways in which Duffy conveys this message is through structural devices. The structural
