39. Name the specific type of plant tissue or cell that performs the following functions: a) waterproofing the surface layer: Epidermis » it produces cutin b) rapidly dividing into new cells: meristematic cells c) transporting sugars throughout the plant: phloem 40. Maple syrup is produced from the sap moving in the xylem of maple trees in the early spring. How would taking too much sap in the spring harm the maple tree? A: Sapwood is xylem, which is food for the tree. It is the stored sugar

CHAPTER I INTRODUCTION 1.1 RESEARCH BACKGROUND This research is about the extraction of keratin protein from chicken feathers using strong fluid extraction process. This extraction procedure utilized a dissolvable as lessening specialists to separate salt linkages, disulphide bond and hydrogen bond of the keratin fiber to break down into protein. Thus, it will likewise diminish the steadiness of keratin strands in the strong structure found in feathers. Proteins are polymer formed by one

Explain the chemical basis of hydrogen bond formation in biology. Discuss the role of hydrogen bonding in the structure and function of biological macromolecules. Your essay should refer to DNA, RNA and proteins. A hydrogen bond is a particularly strong type of intermolecular force which is essential in many biological macromolecular structures and is formed when a hydrogen atom from one molecule covalently bonds to a highly electronegative atom on another molecule, usually nitrogen, fluorine

here are basically three categories of chemicals normally functioning in the body—elements, inorganic compounds, and organic compounds: {draw:frame} Elements are components of all chemical compounds. Of the 92 naturally occurring elements, only 20 are normally found in the body. Seven of these, carbon, oxygen, hydrogen, calcium, nitrogen, phosphorous, and sulfur make up approximately 99% of the human body weight. In most cases, the elements are components of inorganic or organic compounds.

Growth is restricted as the yeast are adjusting to their environment and synthesising cellular macromolecules. Exponential phase: Growth is increasing rapidly at this stage and competition for resources is minimal allowing for the yeast to bud at maximum capacity. Stationary phase: The population is now stabilising as resources become depleted and competition

It is composed of lymphatic vessels, lymphoid tissues and organs, and lymph. The lymphatic vessels are composed of capillaries, collecting vessels, and trunks (Klein, 2010). Lymphatic capillaries drain into the collecting ducts that drain into the trunks. The trunks drain

functions, it folds protein molecules in sacs cisternae, it transports synthesized proteins in the vesicles to the Golgi apparatus. Golgi apparatus: it is made up of membrane bound sacs .The function of the Golgi apparatus is to process and bundle macromolecules like protein and lipids as they synthesize in the cell. It modifies sorts and package proteins to be secreted. Mitochondria: it is of the referred to as the powerhouse . It breaks down food and release energy to the cell. Lysosomes: they organelle
