People don’t want to work in a building in which the floor beams deflect an excessive amount

turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity in aquatic plants. To measure this you would use the light and dark bottle method. Only respiration (R) can occur in the bottle stored in

Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious about these tiny microbes which we cannot be seen through our naked eyes. Therefore I decided to pursue my higher studies and specialisation in microbiology. I started my graduation

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

Organismic Lab Lab1- Dichotomous Key Introduction A dichotomous key is a series of paired statements or questions that are used to categorize organisms with their similarities in characteristics and or structure. The word dichotomous comes from two Greek words that translate to “divided in two parts.” In a Dichotomous key each step has two choices: whether a particular characteristic is present or absent. The questions

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

that cigarettes release more then 20 carcinogens know to promote lung cancer into your body. (Hecht‚ 2010). When looking at the cilia exposed to cigarette smoke in this lab it is seen that they have been greatly slowed down when compared to the uncontaminated cilia‚ and parts of the cells are covered in tar from the tobacco. For this lab it was hypothesized that smoking will inhibit the ciliary action and lower the quality filter the greater affect will be exhibited by the effected cilia. The prediction

hope to fully understand the Stroop effect‚ yet several issues remain open. The primary purpose of this study was to determine whether the Stroop phenomenon is equally strong in both brain hemispheres. Participants collected from our research methods lab were asked to complete an online experiment measuring the time of interference it took them to depict the color of the ink of the color-words. Furthermore‚ each color was assigned a number. For example‚ the ink color red was represented by the number

The appearance of the spectrum from the fluorescent light source was recorded. A discharge tube apparatus was retrieved from a lab cart for demonstration. A hydrogen discharge tube was inserted into the discharge tube apparatus with the spring loaded end first‚ followed by the non-spring loaded end. The discharge tube apparatus was plugged into the outlet. The hydrogen discharge
