that environment plays as much of an important role in development as does genetics? Not so‚ explain the researchers. Popular theory contends that all facets of development are influenced by both genetics and environment. However‚ according to the KCL team‚ exactly how much of your development is determined by genetics and how much is determined by environment may be largely attributed to where you live. Confused? Let me try to explain. Take‚ for example‚ hay fever allergy. If a set of genetically

There is no net movement of water or solutes in any one direction since the concentrations of both are equal on both sides of the membrane. Solutes and water still move in and out but they do so equally. Ringer’s Lactate solution‚ aka 0.9% sodium chloride (or KCl‚ CaCl2‚ etc) is isotonic to human tissue fluid. This solution is infused into the blood stream for a number of reasons: * Irrigation of wounds * Low blood volume (maintain blood pressure if blood is not available) * Low electrolyes (dehydration)

stranded on a desert island. The chemicals involved in modern matches are generally safe‚ but that wasn’t always the case. The material of making a matches is red phosphorus. A chemical equation of lighting a match is: 16KCl3 + 3P4 S3 --> 16 KCl + 9SO2 Actually phosphorus is found in three main forms: white‚ red‚ and black. (There are also numerous allotropes of each of these forms.) White phosphorus is a soft‚ waxy‚ flammable substance‚ consisting of tetrahedral P4 molecules; it is often

ractice Problem #1: Oxygen gas can be produced by decomposing potassium chlorate using the reaction below. If 138.6 g of KClO3 is heated and decomposes completely‚ what mass of oxygen gas is produced? KClO3 (s) --> KCl (s) + O2 (g) [unbalanced] Answer to Practice Problem #1: 1. Balance your equation first. 2KClO3 (s) --> 2KCl (s) + 3O2 (g) [balanced] 2. Convert from grams to moles using molar mass.
