of the Quadriceps femoris. It is also an example of a monosynaptic reflex arc‚ which is simply a neural pathway controlling a somatic reflex. In a monosynaptic reflex arc‚ there is only one motor neuron and one sensory neuron‚ which form a single chemical synapse. This means when the patellar tendon is tapped with a reflex hammer‚ there needs to only be a very brief stimulation to the muscle spindles. These muscle spindles provide the feedback that the brain needs to regulate tension in skeletal muscles

white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations are referred in research and‚ in fact‚ are sometimes the only physical records of what a now-extinct (or near-extinct) fish look like in life. New technologies can only add to information we know about previously described species. Different kinds of animals have different body coverings. Marine vertebrates include

analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce proteins which are called enzymes and their job is to help reduce the amount of energy needed to start a reaction. Enzymes are catalysts which are chemical substances that reduce the amount of activation energy needed for the reaction to begin.

Dependent variable- the temperature of water Controlled variables- the amount of water in the calorimeter - The stop watch - and the thermometer used. Theory- Temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold. Objects of low temperature are cold‚ while various degrees of higher temperatures are referred to as warm or hot. When a heat transfer path between them is open‚ heat spontaneously flows

Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence

Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps

Introduction – Lab Report What is a Chemical Reaction? A chemical reaction is a change in matter that produces one or more new substances. A chemical change or reaction occurs when bonds are broken and new ones are formed. The formation and dissolution of these bonds are dependent upon environment changes. Even without the usage of microscopes‚ chemical reactions are usually apparent to the naked eye. The two main kinds of changes that one can observe are the formation of new substances and changes
