accelerating‚ unless it is disturbed by an outside force. Two conditions for equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. Thus‚ the following objectives were emphasized in this experiment: to determine the equilibrant force using the force table and the component method‚ to determine the unknown forces using the first condition and second conditions for equilibrium‚ to locate the centre of gravity of a composite body‚ and to demonstrate

water and part chemicals. The chemicals that help make up life are constructed mainly of carbon. A compound that has carbon in its composition is called an organic compound. Organic compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size. Atoms have diverse characters that

PSYC 101 – Experiment Assignment (40 pts) Students will carefully observe acts of aggression and prosocial behavior on television‚ report their observations‚ and analyze their data to draw conclusions. Watch 20 minutes of each of the three types of programs (do not code behavior in commercials). Record every aggressive act and prosocial act. Some categories will have several acts. Your chart and discussion will focus on comparing the following three types of programs you will watch: 1) children’s

most part‚ life is cellular. Although there are several other requirements‚ that an organism needs to be considered alive. These requirements are macromolecules‚ it needs to have metabolism‚ and be able to reproduce. If something has all of these things then it can be considered alive. The first requirement is that it has to have cells. Beings also need macromolecules because they need energy. The four macromolecules are carbohydrates‚ lipids‚ proteins‚ and nucleic acid. Macromolecules are used for

composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed. ABSTRACT Tissue types have a variety of compositions‚ and one way to describe these differences is by comparing macromolecule content. The four macromolecules – lipids‚ proteins‚ carbohydrates‚ and nucleic acids – can be quantified and analyzed.

A Macromolecule is a molecule with a very large number of atoms .The word macromolecule is usually used for describing polymers. Molecules that are made up of smaller molecules are called monomers‚ there are also Organic Molecules composed of carbon atoms .The functions of the Four big Macromolecules: First‚ Carbohydrates‚ carbohydrates is the function of being used for energy production during cellular respiration. Second ‚ Lipids‚ lipids are used for four things; insulation and long-term energy
