Chapter 2 REVIEW OF RELATED LITERATURE AND STUDIES Related Literature Spider silk (Parasteatoda tepidarium) commonly known as agiw in Filipino‚is a material spun by varieties of spiders.Spider silk has a unique combination of mechanical strength and elasticity that makes it one of the toughest materials we know.(Arizona State University‚2013). Furthermore‚silk consists of very repetitive blocks of mainly glycine and alanine.These are the simplest and smallest amino acids allowing strands to be packed

Biology notes The search for better health Discuss the difficulties of defining the terms ‘health’ and ‘disease’ - Disease is any condition that impairs normal living processes and is recognised by the presence of specific symptoms - Many diseases are best understood as a disturbance of homeostasis - Health is a state of complete physical‚ mental and social well-being and not merely the absence of disease or infirmity - ‘Health’ and ‘disease’ are not always easy terms to define - For example‚ someone

although not all of them are native (1). Woodlouse is a crustacean‚ which fit into the class of arthropods‚ crustaceans are primarily aquatic animals. It is for this reason that woodlice become dehydrated in dry conditions‚ and their outer shells aren’t waterproof (1). Therefore damp environments are preferable for woodlouse to survive. The structure of woodlice are similar to all arthropods‚ the body is split up into segments‚ with an exoskeleton and jointed limbs. Firstly‚ the head and

Genetics: the science of heredity that includes the study of what genes are‚ how they carry info‚ how they are replicated and passed to subsequent generations of cells or passed between organisms‚ and how the expression of their info within an organism determines the particular characteristics of that organism. Genome: the cell’s genetic information that includes it’s plasmids and chromosome. Chromosomes: structures containing DNA that physically carry hereditary info‚ contain the genes Genes:

READING MATERIAL 1. Explain the three hypotheses for the recent changes in the toxicity of venom in different species of rattlesnakes found in the United States. - Interbreeding between snakes with different venom profiles. - Geographic distribution (genes shifted eastward) - Convolution - Old rattlesnakes have high concentration of toxic. 2. What is an “evolutionary arms race”? Describe how this applies to one of the hypotheses suggested to explain toxicity of venom in rattlers

Do the yeast cells have a definite shape or is there considerable variation? Yeast cells seem to vary in shape‚ some look to be more oval and round‚ although. some slides did show pear and cylinder shapes. 2. Can you detect any subcellular structure? I cannot detect a clearly visible
