Age spots form when the skin produces an excess amount of pigment called melanin. This pigment is what gives your skin its normal color. Age spots are also called liver spots and sunspots and are usually flat brown or black spots on the areas of the skin that are most often exposed to the sun such as face‚ shoulders and forearms. They can also form when the skin is exposed to artificial tanning such as heat lamps and tanning beds. Age spots may develop on younger people if they spend a lot of time

It cannot cleaves the peptide bonds at the terminals. Endopeptidase is unable to break peptides into monomers. 3. Ang (1-9) causes vasodilation by increasing nitric oxide. Also‚ decreases the fibrosis and hypertrophy. But‚ Ang (1-7) decreases the collagen synthesis‚ fibroblast proliferation and cardiomyopathy. However‚ Ang (1-7) increases the left ventricular systolic presser and causes vasodilation by increasing the cAMP. 4.

Unit 5 P2 Explain what they are‚ their functions and where they are found. Then go into detail about two organs‚ with their functions‚ what tissues they are made of and where they are found in the body. Tissues: Tissues are groups of similar cells that have specific functions. In this piece of work I’ll talk about these types of cells: Epithelial Tissues: Epithelial are the lining of internal and external surfaces and body cavities‚ including tubes/channels (ducts) carrying secretions from glands

1 Lifestyle‚ health and risk ■ HSW 1.1: Criterion 5 – Water as a liquid at room temperature Criterion 5: Analysis and interpretation of data to recognise correlations and causal relationships Consider the water molecule‚ its properties and its physical state. Water has a relative molecular mass (Mr) of only 18‚ yet it is a liquid at room temperature. This is surprising; it contrasts with other small molecules‚ which are usually gases at such temperatures. Examples include methane (CH4

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds‚ the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen

Case Study 1: Amanda October 20‚ 2013 A. Amanda’s bones are weak and break easily due to an impaction in the collagen structure of her connective tissues. The functioning parts’ of the skeletal system that is compromised in brittle bone syndrome is the diaphysis which is the top the main portion of bone‚ the epiphyses which is the distal part of the bone‚ the metaphases the region between the diaphysis and epiphyses‚ the epiphyseal plate which is the layer of hyaline cartilage

which have to be light or our eyes would always be closed. The dermis‚ or known as the true skin‚ is thick‚ sturdy‚ and contains lots of nerves‚ blood vessels‚ and sweat glands. It protects and repairs injured tissue. This layer holds more collagen‚ which comes from cells called fibroblasts and is one of the strongest proteins found in nature. It gives skin durability and resilience. The subcutis‚ joined to the dermis‚ is the deepest layer of the skin. It contains lipocytes‚ which produce
