Biology Assignment (Haemoglobin) Proteins are large‚ complex molecules that are made up of hundreds or thousands of smaller units called amino acids‚ which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. The sequence of amino acids determines each proteins unique structure and specific function. They play many critical roles in the cells. They can be grouped as enzymes‚ antibodies‚ messengers‚ structural components or

Chapter 12: Cardiovascular System 12.1 3 types of blood vessels * Arteries: carry blood away from the heart to the capillaries * Capillaries: permit exchange of material with the tissues * Veins: return blood from the capillaries to the heart. Arteries Wall has 3 layers * Endothelium: inner layer‚ made up of simple squamous epithelium‚ with a connective tissue basement membrane that has elastic fibers. * Middle layer: thickest later and consists of smooth muscle that can

After entering the lungs‚ the branches subdivide‚ finally emerging as RATIONALE capillaries which surround the alveoli and release the carbon dioxide in exchange for oxygen. The capillaries

Chromosome 11 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 11 spans about 134 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells. Identifying genes on each chromosome is an active area of genetic research. Chromosome 11 likely contains between 1‚300 and 1‚700 genes. Genes on chromosome 11 are among the estimated 25‚000 total genes in the human genome. There are many

Reproductive System 1. How is a vasectomy performed? Be sure to cite the specific anatomical structures involved. How does this prevent pregnancy? Vasectomy refers to the surgical procedure that involves male fertilization that helps to perform lasting birth control. During this procedure‚ surgeon cut off part of the male anatomy called vas deferens that transports sperm from the epididymis to the ejaculatory ducts. It prevents further sperm entering into the seminal stream. After this procedure

Ticks constitute the Suborder Ixodida‚ of the acarine Order Parasitiformes‚ and are exclusively parasitic. The Ixodida contain three families‚ the Ixodidae ‚ Argasidae ‚ and Nuttalliellidae. The specimens collected in our data are of the Amblyomma genus falling under the Ixodidae family. (Horak et al.‚ 2002). Amblyomma life cycle includes four stages: the egg‚ larva‚ nymph with only one nymphal instar‚ and adult. All ticks feed on blood during some or all stages in their lifetime because they are

The Blood Circulatory System The Circulatory system is a system in the bodies of all organisms that moves the nutrients that are needed as well as gases and wastes to and from cells and helps fight unwanted bacteria and other diseases. It also helps alleviate the body temperature to maintain homeostasis‚ which is the property of either an open system or a closed system in a living organism. It brings the body’s cells what they need in order to survive – oxygen and nutrients. The center of the circulatory
