Adriana Rempson Mrs. Steeger AP Biology-7 10 October 2012 Transpiration in Plants Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment. Introduction: Pants absorb and

Healthy living is many things. It’s not being the skinniest person ever‚ nor is it being fat. It’s eating enough‚ eating proper food and exercise regularly. Of course‚ I think it’s okay to sometimes eat some chips or take a glass of cola‚ but not all time. Encourage to do physical activity is harder to some than it is to others. For some‚ it’s the easiest thing to go to the gym‚ or start jogging‚ while others can’t get themselves started. And I know a lot a people who don’t understand that. If

In this experiment‚ we worked with potatoes‚ also known as solanum tuberosum (Watkins‚ n.d). Potatoes are starchy crops that provide a lot of energy. For this experiment‚ our hypothesis was: If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The

Week 9 Week 9 Application: Diffusion of Responsibility Pro-Social Behavior Conceptually‚ pro-social behavior includes behavior intended to benefit others‚ including behaviors such as helping‚ comforting‚ sharing‚ cooperating‚ reassuring‚ defending‚ and showing concern (Fiske‚ 2012‚ pg. 342). Pro-social behavior is intended to help another individual or group‚ but not benefit the self. Pro-social behavior reflects four types of social motivation‚ which reflects our core social motives (Fiske

Chapter 4 Microscopes Two important factors in microscopy are: 1) Magnification: an increase in the object’s apparent size compared with its actual size. 2) Resolving Power: the ability of an optical instrument to show two objects are separate. Three types of microscopes: 1) Light Microscope (LM) M: 1000x RP 0‚2 micrometer (small bacterial cell) 2) Electron Microscope (EM) uses a beam of electrons to resolve electrons‚ better resolving powers than light microscope M:100‚000x RP 0

This is a mixture of medicine and biology‚ which analyses the effects of a drug on a cell‚ tissue‚ organ or organism. A pathologist is what Sir Howard Florey did‚ in studying diseases‚ learning about it and diagnosing the disease. His best-known work dates from his collaboration with chain‚ which began in 1938 when they conducted investigation of the properties of naturally occurring antibacterial substances.

DIFFUSION OF INNOVATION TO DEVELOP STRATEGIES TARGETED TO THE ADOPTERS CATAGORIES ABSTRACT In this discussion‚ company dealing with the diffusion of innovation‚ which how can a new product/service absorbed by the market on the basis of time‚ social system‚ distribution and price. Specifically‚ dealing with the consumers which adopt an innovation. According to the adaptation‚ consumers are classified into the five categories which are innovators‚ early adopter‚ early majority

(HGT)‚ also known as lateral gene transfer (LGT)‚ “is the movement of genetic material between unicellular and/or multicellular organisms‚” (Wikipedia‚ 2017‚ p.1). It is the primary mechanism for the spread of antibiotic resistance in bacteria. Question 4: discuss the danger that antibiotic resistance poses in today’s society‚ consider how man has contributed to this and suggest any strategies that you think may be able to halt it or prevent its expansion Antibiotic resistance occurs when an antibiotic
