negative controls to determine the macromolecules present in an unknown solution Course # 6130‚ Wednesday‚ 7-10 PM‚ B2-151 Lab performed: September 21st‚ 2011 INTRODUCTION Every living thing is dependent on large complex molecules‚ known as macromolecules. The objective of this lab was to correctly identify which macromolecules the unknown solution was comprised of using various substances as experimental controls. There are four major types of biological macromolecules - carbohydrates‚ lipids‚ proteins

We only used 200g of chopped fruit peels (banana and papaya)‚ 1.5 distilled water‚ 3 gulaman bars and etc. This product efficiency must estimate three trials having three replication each. After three trials that the study is not proved‚ it will be considered failure. The paper covers five important chapters namely: the problem

[2] According to some users and scientific studies‚[3] regular usage of the IR Sauna can assist in alleviating pain. The heating of the body’s muscles and tissues by the radiant heat may decrease the aches and pains by relaxing the muscles.[4] Proponents of FIR sweating claim a toxin content of up to 15%

We then proceeded to let the trolley ‘roll’ down the ramp with no weights on top. We then repeated this 3 times (to provide us with a fairer‚ more realistic time). We then recorded the times in a table. We then repeated step 2‚ except we added a ** gram weight on top. This was attached by a elastic band. We tried to keep all of the variable constant‚ apart
