Pre-Lab 1 Assignment Quantitative Analysis of Biomolecules Biochemical analysis involves the characterization of biomolecules within a sample using appropriate laboratory techniques. There are two principal approaches: 1. Qualitative analysis – where a sample is analyzed to determine whether a biomolecule is present or absent. As an example‚ a blood sample might be analyzed for a specific antibody or a bacterial cell might be probed for a nucleic acid sequence. 2. Quantitative analysis

would not be accessible for transcription. Before the chromosomes condense the nuclear membrane goes through meiosis which is cell division between and egg and sperm cell that determines the sex of a baby. The sex is found by the sperm which carries a X and Y sex chromosomes. Before the cell divides two sets of chromosomes pair together and swap segments. The second part of our questions was on the bases of chromosomes and how they condense and also how microtubules work to allow cell division. One

It is observed that the absorbance level increases as the amount of albumin is added more in different test tubes‚ while the amount of KCl decreases.

faster. Meaning- they need more oxygen and glucose and release more carbon dioxide. A faster breathing rate means that oxygen can be taken into the body at a faster rate and carbon dioxide can be released faster. Cardiac output = stroke volume x heart rate Effects of exercise: Ventilation – breathing Respire – release of energy from food/chemicals Anaerobic respiration … is release of glucose without using oxygen. This produces lactic acid. glucose = lactic acid +
