Exam 1: Introduction: Evolution and Themes of Biology

Use the following information to answer the questions below. Golden algae are a group of photosynthetic protists whose colour is due to carotenoid pigments: yellow and brown.A group of students was given a significant sample of golden algae (Dinobryon); this algae is colonial and has flagella.Their instructions for the project were to design two or more experiments that could be done with these organisms. -The students plan to gather data from the project.Which of the following would be the best way to present what they gather from experimental groups as opposed to controls?

Use the following information to answer the questions below. Golden algae are a group of photosynthetic protists whose colour is due to carotenoid pigments: yellow and brown.A group of students was given a significant sample of golden algae (Dinobryon); this algae is colonial and has flagella.Their instructions for the project were to design two or more experiments that could be done with these organisms. -For their second experiment,the students want to know whether the Dinobryon have to live in colonies or can be free living.How might they proceed?

Which of the following is (are)true of natural selection?

Why is the theme of evolution considered to be the core theme of biology by biologists?

Which of the following is true about the diversity of life?

When a hypothesis cannot be written in an "If…then" format,what does this mean?

Use the following information to answer the questions below. Golden algae are a group of photosynthetic protists whose colour is due to carotenoid pigments: yellow and brown.A group of students was given a significant sample of golden algae (Dinobryon); this algae is colonial and has flagella.Their instructions for the project were to design two or more experiments that could be done with these organisms. -Since these organisms are protists,which of these characteristics could the students assume to be true?

Which of the following is the main goal of systems biology?

A filamentous organism has been isolated from decomposing organic matter.This organism has organelles and a cell wall but no chloroplasts.How would you classify this organism?

Organisms interact with their environments,exchanging matter and energy.For example,what do plant chloroplasts convert the energy of sunlight into?

Given the cooperativity of science,which of the following is most likely to result in an investigator being intellectually looked down upon by other scientists?

The following is a list of biology themes discussed in Chapter 1.Use them to answer the questions below. I.New properties emerge at each level in the biological hierarchy. II.Organisms interact with other organisms and the physical environment. III.Life requires energy transfer and transformation. IV.Structure and function are correlated at all levels of biological organization. V.Cells are an organism's basic units of structure and function. VI.The continuity of life is based on heritable information in the form of DNA. VII.Feedback mechanisms regulate biological systems. VIII.Evolution accounts for the unity and diversity of life. -Which theme(s)is/are best illustrated by a group of investigators who are trying to classify and explain the ecology of the community living within a specific region of prairie grassland?

Which of the following statements is true?

Charles Darwin proposed a mechanism for descent with modification that stated that organisms of a particular species are adapted to their environment when they possess which of the following?

In a hypothetical world,every 50 years people over 6 feet tall are eliminated from the population before they reproduce.Based on your knowledge of natural selection,what would you would predict about how the average height of the human population will change over time?

An organism was discovered that is 50 uM in length and eukaryotic.Which of the following categories is the organism most likely to fall into?

The method of scientific inquiry that draws conclusions from careful observation and the analysis of data is known as which of the following?

Prokaryotes are classified as belonging to two different domains.What are the domains?

In a high school laboratory,which of the following constitutes an experiment? I.learning to use a microscope by examining fixed specimens on slides II.being able to examine swimming protists under a microscope III.extracting pigments from plant leaves and separating the types of pigments for identification IV.preparing root tips for examination by staining them

Why are protists now placed is several groups rather than in one kingdom?
