Math Practice Lab Pre-Lab Questions: 1. The rules concerning handling significant figures are as follows: When dividing/multiplying The answer has no more significant digits than the number with the fewest significant digits (the least precise figure). Round off after calculations have been performed. When adding/subtracting Answer has no more places than the addend‚ minuend‚ or subtrahend with the fewest number of decimal places. Significant figures are irrelevant when adding/subtracting

production of gametes and spores. Materials: This lab required prepared slides of whitefish blastula‚ onion root tips‚ ovary‚ and testis‚ a microscope‚ and chromosome kit. The prepared slides of whitefish blastula and onion root tips‚ ovary‚ and testis were observed under the 10x and 40x objectives. Mitosis is easily observed in cells that are growing at a rapid pace such as whitefish blastula or onion root tips‚ which was used in this lab experiment. The root tips contain and area called

Techniques and Measurements Lab 1 The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know‚ identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions‚ measurements‚ and weights to then calculate using algebraic formula. Throughout lab one we were introduced to many different
