LAB #2 QUESTIONS PART A: ENDOCRINE GLANDS OF THE HUMAN 1. Complete the following chart: Please see the attached chart for the Endocrine System. 2. Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

and objectives of this lab was to be able to draw completed electrical circuits using the correct symbols for selected electrical components‚ including batteries and diodes. Another focus was to calculate the proper resistance using Ohm’s law‚ use proper electrical currents and quantities‚ and lastly measure voltage and resistance in an electrical circuit using a multimeter.

Introduction Transpiration is a process which is similar to the evaporation. Water is lost at the surface of the plant such as leaves‚ stems‚ roots and flowers in the form of water vapor. It creates a pulling. Force which causes continuous upward movement of water and mineral salts and this force is called transpiration pull. Apart from to water‚ gas like carbon dioxides from the air can also pass through by the pore of the surface of the plants for photosynthesis. But in this experiment‚ we

Laura Lugo Group: Bianca Jonson Short lab report 10/4/14 Effect of household drugs on circulatory system of Lumbriculus Variegatus (blackworms) Hypothesis & justification part 1: In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate‚ an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1‚ we observed the basal rate of three different worms‚ and then placed the same three worms on different concentrations

In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment
