Chapter 5: Water and Seawater • Water has many unique properties, both chemical and physical. • Salts and other dissolved compounds in seawater. • Ocean water salinity, temperature, and density vary with depth. Water's structure defines its many properties • Atoms – building blocks of all matter • Subatomic particles – Protons – Neutrons – Electrons • Number of protons distinguishes chemical elements Water is a molecule • Strong covalent bonds between one hydrogen (H) and

1950 Introduction Physiological breakdown of the fruits of the pineapple [Ananas comosus (L.) Merr.] is characterized by a darkening of the flesh of the fruitlets, beginning near their attachment to the core in a region an inch or two above the base of the fruit. The-disorder progresses upward and outward, subsequently involving all of the fruitlet except the ovary and a layer approximately one quarter inch deep below the skin. Only in advanced stages do the surface of the fruit and the core

Molecules, Biodiversity, Food and Health Biological Molecules Biological Molecules (a) describe how hydrogen bonding occurs between water molecules, and relate this, and other properties of water, to the roles of water in living organisms; Water is a polar molecule. This is because the oxygen atom pulls the shared electrons towards it, meaning that water is slightly negatively charged at the oxygen and positively charged at the hydrogen ends, so they can form hydrogen bonds with each other

with α 1-4 linkages, and 1-6 side chains, and are used for storage. 7. Amino acids are the monomers of proteins – they have an amino group at one end, and a carboxylic acid group at the other. 8. The ‘R’ group distinguishes one amino acid from another – there are about 20 in total; those that are needed in the diet are called essential amino acids. 9. Some amino acids can be synthesised by transamination. 10. Amino acids bond like monosaccharides, creating peptide bonds. 11. Fibrous proteins,

Notes: Chapter 2 I) Matter- consists of chemical elements in pure form and in combinations called compounds. A) Elements- a substance that cannot be broken down to other substances by chemical reactions. 1) Hydrogen, oxygen, nitrogen, and carbon make up 96% of living matter. 2) Other 4% include phosphorus, sulfur, calcium, and potassium. They’re called trace elements- those required by an organism in only minute quantities. B) Compounds- a substance consisting

and other fields requiring bio products. Father of the term biotechnology is ‘Karl Ereky’ and Father of Biotechnology was ‘Louis Pasteur’. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Ribonucleic acid or RNA, is one of the three major macromolecules (along with DNA and proteins) that are essential for all known forms of life. A pipette (also called a pipet

is the process of analyzing an individual’s DNA base-pair patterns. The DNA fingerprinting lab involved identifying the suspect using Agarose Gel and Polymerase Chain Reaction. It was found that suspect two s DNA matched the crime scene DNA. This is known because suspect twos DNA traveled the same distance as the crime scene DNA. DNA Fingerprinting Using Agarose Gel Introduction In 1984 Dr. Alex Jeffreys came up with deoxyribonucleic acid (DNA) fingerprinting, which is also known as DNA
