Exercise 1: Data Interpretation
Table 1: Water Quality vs. Fish Population Dissolved Oxygen (ppm) | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | Number of Fish Observed | 0 | 1 | 3 | 10 | 12 | 13 | 15 | 10 | 12 | 13 |
(hint: ppm stands for “parts per million”) 1. What patterns do you observe based on the information in Table 1?
Ans. The quality of fish increase as (ppm) increase to a point while the quality of water continue to increase 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. Ans: If oxygen or ppm in the water increase more fish will be produce

3. What would your experimental approach be to test this hypothesis? Ans. My experimental approach will be gather data, by doing background research, and test experiment by having a independent, and dependent variable. I will analyze my result and make conclusion

4. What are the independent and independent variables? Explain why each was chosen. Ans. My dependable variable will be water with high level of (ppm) which will increase…...

...Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size of the island will influence the population. • The amount of precipitation will influence beak size. • Variances in beak size will influence beak size. MATERIALS The materials needed for this experiment consist of a computer and access to the Evolution Lab on the University of Phoenix student website. In the Evolution Lab there are two islands, Darwin Island and Wallace Island. There are seven variables that can be changed to run many different experiments on both islands. The variables are beak size, variance of beak size, heritability, clutch size, island size, population, and precipitation. METHODS In all of the experiments Darwin Island was used as the control group and Wallace Island was the experimental group. So, in each test, the variables for Wallace Island were altered and the variables for Darwin Island were left alone. The first experiment was to determine whether or not the size of the island affected the population. To do this, the only variable......

How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts, huge volcanic eruptions, or great earthquakes? Uniformitarianism is a theory that states that past events are happening today and will happen in the future. What we do today has an effect on the geologic formation and structure and can lead to natural disasters. 5. In what ways do geologic processes affect your daily life? Daily life can be interrupted by flooding, tornadoes, earthquakes and wildfires destroying communities and resources that provide stability. Chapter 2: Critical and Creative Thinking Questions 1 & 3 1. When astronauts brought back rock samples from the Moon, the minerals present were mostly the same as those found on Earth. Can you think of reasons why this might be so? Would you expect minerals on Mars or Venus to be the same, or at least very similar, to those on Earth? Moon and Earth are close neighbors so some of the similarities are to be expected. Mars, Venus and Earth are inner planets and similar because they are small and made up of solid rock like materials. 3. Which of the following materials are minerals, and why (or why not)? Water; beach sand; diamond; wood; vitamin pill; gold nugget; fishbone; emerald. Water is not a mineral because it is a liquid. Beach sand...

Write a 100-word summary explaining how the chosen media piece supports the statement. Include reference citations. 1. Find a media piece—article, video, presentation, song, or other that recognizes the fundamental concepts of chemistry in biology. Include a link or reference citation for the piece and describe how it helped you better understand how fundamental concepts of chemistry affect biology. After my research at www.infoplease.com it has helped me to understand how fundamental concepts of chemistry affects biology by breaking down the concept of why chemistry and biology goes hand in hand. Infoplease, (2000-2014), stated that biology explained the living parts of the world and their environment. It also said that biology requires a little knowledge of chemistry and that it is important to know aspects of chemistry to make biology come alive. We all know that the understanding of chemistry requires a little mathematic but it is not important to go into detailed mathematical applications to understand the principles of biology. So what is the fundamental concepts of chemistry in biology? Biology overlaps with chemistry in explaining the structure and function of all cellular processes at the molecular level.

...1. Each chloroplast has two outer membranes, which encloses a semi-fluid interior called the stroma. I inside the stroma is a third membrane called the thylakoid membrane. It located in the thylakoid membrane of the chloroplast. It is the light-independent reactions take place. The thylakoid membrane absorbs photon energy of different wavelengths of light. Embedded in the thylakoid membranes are photosystems: Clusters of 200 to 300 pigments and other molecules that surround a pair of chlorophyll a molecules. In plants, there are two photosystems, Photosystem I and Photosystem II. The light-dependent reactions begin in photosystem II. When a chlorophyll a molecule within the reaction center of PSII absorbs a photon, an electron in this molecule attains a higher energy level. The begins with Photosystem II, where trapped light energy is used to split water, a process known as photolysis: H2O → 2H+ + 2e−+ O. It located in the thylakoid membrane. The electron is transferred from one to another molecule and creates a chain of redox reactions. It is an electron transport chain (ETC). Along the way, the energy released by the electrons is used to make ATP in a process called photophosphorylation. The molecular details of this ATP-generating system are similar to those used by the mitochondrion in oxidative phosphorylation. Phosphorylation refers to the addition of a phosphate group ADP to form ATP. The reaction sequence is: ADP + Pi → ATP. The electron flow......

...Biology 111 Laboratory: #1 Name: Title: The Scientific Research Method: The Dominant Thumb Experiment with Regard to Individual’s Handedness 1. Abstract The experiment was to determine if there is a relationship between thumb dominance and hand dominance. The experiment involved people to clasp their hands together and then seeing if the thumb of the dominant hand would overlap the thumb of the non-dominant hand. The research showed that there is no correlation between being one-handedness and having the same thumb dominance. There could be other factors that may influence the thumb dominance based on which portion of the brain an individual use more (whether they are right or left-brain), possessing particular alleles genes, or by having dominant or recessive traits. 2. Introduction A Background Information About 90% of the world’s population is people who are right-handed, and the remaining 10% is filled with left-handers (Price, 2009). Particular genes known as “alleles” can influence the handedness of a person either through inheriting dominant or recessive allele (Port, 2007). There has also been research of how “brain lateralization”, which is the hemispheres of the brain, is utilized more by either left or right-handers (Holder, 2005). B Purpose This experiment will verify when hands are clasped together, if there is a relationship between the dominant hand and which thumb will be on top of the other thumb. The main issue of concern is......
