1. SURFACE RUNOFF INTRODUCTION: Runoff means the draining or flowing off of precipitation from a catchment area through a surface channel enters into a stream channel. It is convenient to visualize three main routes of travel; overland flow (air hujan limpahanpermukaan)‚ interflow‚ and ground water flow (air dari punca bawah tanah). 1 Runoff results from rainfall occurrence in a hydrologic catchment. Rainfall-runoff relations are Interflow/subsurface and base flow/groundwater flow

GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering the heart)‚ the

Cultural Diffusion and its Influence on Europe and Sub Saharan Africa Both Europe and Sub Saharan Africa was and still is a melting pot consisted of a blend of races and cultures that has integrated into a cohesive whole. Take The Melting Pot restaurant as an example; The rich blend of the chocolate sauces can resemble a specific culture such as strawberry‚ white‚ dark‚ raspberry‚ etcetera‚ but when they are mixed together‚ the melting pot creates a swirl that symbolizes the blending of one culture

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

Experiment #1 Date: September 13‚ 2011 Title: Diffusion in Gases I Aim: To observe the diffusion of bromine Apparatus and Materials: Glass tube‚ bromine‚ fume chamber Diagram: Procedure: -Liquid bromine was placed in a jar and covered Observations: When first placed in the jar the original color of bromine was red-brown. As it began to diffuse its color changed from dark brown to a lighter brown until it becomes a yellow-like orange color. As it was diffusing liquid bromine changes its state

Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the

1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1
