BSC2011C Final Review Unit 1 Review Ch. 25‚ 22‚ 23‚ 24‚ 26‚ 19‚ 27 Ch. 25 1. Life is metabolism and heredity. Metabolism is the mechanism that creates order and complexity from chaos‚ by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication‚ ii. Inheritance‚ iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits

In this context we may ask: What are living things? We humans‚ ourselves are living things. How do living things differ from non-living things? To answer these questions‚ we must first define the word life

Evaluation of antidiabetic and antimicrobial activity of jasminum grandiflorum leaves INTRODUTION 1.1. The pancreas and insulin formation The pancreas is an elongated organ situated next to the first part of the small intestine. It is both an endocrine gland that produces hormones‚ such as insulin and glucagon‚ and an exocrine gland producing digestive enzymes‚ such as trypsin and chymotrypsin (Martini‚ 2004). It is located behind the stomach‚ between the spleen and the duodenum (see Figure

1.1.1 In small unicellular organisms‚ substances move around slowly by diffusion. Diffusion is too slow to move substances round the larger bodies of multicellular organisms. They have a circulatory system: substances are carried in blood pumped by a heart. In a closed circulatory system (eg in vertebrates) blood is enclosed in narrow blood vessels. This increases efficiency: blood travels faster as a higher pressure is generated. Valves ensure blood flows in one direction:

Control‚ Genome and Environment Cellular Control & Variation Cellular Control (a) state that genes code for polypeptides‚ including enzymes; (b) explain the meaning of the term genetic code; The sequence of the bases on a gene is a code with instructions for the construction of proteins. It has a number of characteristics: It is a triplet code- three bases code of an amino acid It is a degenerate code- All amino acids bar one have more than one code Some codes don’t code for amino acids

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:
