The Digestive Systems
The Digestive Systems
The Digestive Systems The digestive systems works on nutrients taken from the environment, breaking them down into simpler products, and then absorbing the products together with water and salts so they can be used in metabolism. The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeletons of arthropods, and so on and foreign proteins or carbohydrates are rarely incorporated unchanged. They are usually first broke

The Plant Cell
The Plant Cell Cell Wall Size: Around 1? Basic Function: * Hold the shape of the cell. * Strengthen the cell. Covering the cell membrane of the plant cell, there is the cell wall. The cell wall is composed of two layers of rigid, hard cellulose embedded in compounds like pectin and lignin. Pores in the cell wall allow molecules to pass through. The cell wall has two parts. The primary cell wall is formed during the growth of the cell. After the cell has stopped growing, a secondary cell wall for

Genetic Engineering, history and future Altering the Face of Science Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply af

Spent Mushroom Waste
Spent Mushroom Waste as a Media Replacement for Peat Moss in Kai-Lan (Brassica oleracea var. Alboglabra) Production , Spent mushroom waste (SMW), otherwise known as spent mushroom substrate (SMS) or spent mushroom compost (SMC), is the leftover after different flushes of mushrooms have been harvested [6]. Normally, at the end of each production cycle, “spent” (used) mushroom substrates are left abandoned or discarded. One of the major environmental problems in the mushroom producing countries re

High Protein Diet and Human Health
High Protein Diet and Human Health February 8 2016 MYP Year 4 B By Naim Al-Haj Ali  Many people try to lose weight using different diets and ways, maybe by using some kind of medicines or herbs, other people try to go to the gym more to burn more fat. Some people choose high protein diets, and others choose low protein diets. But what is the difference? And how do they work? At first, to understand how the diets work, we need to understand the difference between proteins and carbohydrates. The

Background information: Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very specific and don\'t just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The activity of enzymes is affected by three factors; temperature, concentration, and
