experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity‚ then more oxygen and glucose molecules will be produced‚ and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of oxygen

Homework 3 Probability 1. As part of a Pick Your Prize promotion‚ a store invited customers to choose which of three prizes they’d like to win. They also kept track of respondents’ gender. The following contingency table shows the results: | MP3 Player | Camera | Bike | Total | Men | 62 | 117 | 60 | 239 | Woman | 101 | 130 | 30 | 261 | Total | 163 | 247 | 90 | 500 | What is the probability that: a. a randomly selected customer would pick the camera? 247/500= 0.494=

What is a possible hypothesis for this study? Samantha believes the E-Z program will help improve the student’s grades. Samantha made a formal prediction about the relationship between the students and the new reading program. The hypothesis she made is a testable theory that will prove the results of the program (Burger‚21) Whose class is a control group and why? Mrs. Brown’s class will be the control group. Mrs. Brown’s class did not receive the new reading program. The control group are the

Hypothesis Contrary to Fact Since the first man walked this earth‚ we have been trying to understand why everything is the way it is. Why do things work the way they do? What happens if you put this with that? Humans have always been determined to learn and understand everything they can. As a result‚ the knowledge that beings have acquired and the patterns in subjects have come to be facts. These facts show the definite ways that objects‚ persons‚ and events function. After studying‚ one can

The data found in this experiment supported the initial statement in the hypothesis‚ that blue would have the highest rate of photosynthesis (see Figure 7). The second part of the prediction was refuted by the data‚ as green had a higher rate than both yellow and red. This result seems to go against the experiment‚ however the answer is in Figure 5. When adding green food coloring to the solution (see Methods) dilution also took place. When comparing the wavelength of 540 nm (see Tables 1 & 2) with

Efficient market hypothesis (EMH)‚ first promulgated by Eugene F. Fama (1970)‚ suggests that financial markets price assets precisely at their intrinsic worth given all publicly available information. Though several empirical works strongly confirm market efficiency‚ some of the hypotheses do not agree with the efficient market hypothesis‚ such as behavior finance hypothesis. This essay will discuss the assumption of efficient market hypothesis and implications when these assumptions do not hold

countable set is given‚ any other set which can be put into a one-to-one correspondence with is also countable. Countably infinite sets have cardinal number aleph-0. While on the other hand‚ continuously infinite numbers‚ also known as continuum hypothesis‚ proved by the German mathematician Georg Cantor‚ states that there is no infinite set with a cardinal number between that of the "small" infinite set of integers and the "large" infinite set of real numbers (the "continuum").

QUESTION 1 Most of the research on input has developed from Stephen Krashen’s Input Hypothesis. According to the Hypothesis‚ for L2 acquisition to take place‚ the learner must be exposed to comprehensible input. In other words‚ Krashen answers the question about what mechanisms exist to allow learners to acquire a second language. He reaches a conclusion‚ stating that learners can achieve acquisition “by understanding messages‚ or by receiving comprehensible input.” Furthermore‚ the input must contain

Question 2 a.) Rubisco is a key component in photosynthesis. It is an enzyme involved in the fixation of atmospheric carbon dioxide. b.) Due to global warming‚ the increased temperature can influence Rubisco which can catalyses oxygenation over carboxylation. During carboxylation CO2 is fixed and raised temperature enhancing oxygenation. c.) Level of PGA depends on Rubisco with who is going to bind. Rubisco is an enzyme that reacts with CO2 and O2. The reaction with O2 competes with carboxylation
