Concept explainers
For each statement, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the theme descriptions in this chapter.
10. By comparing genes between green sea turtles and humans, insight can be gained into how those genes encode specific physical traits.

- Please solvearrow_forwardWhich of the following statements describe how genes, proteins, and traits are related? Select all that apply. The nucleotide sequence of a gene determines the amino acid sequence of a protein. Genes contain information about traits. Genes carry out functions in the cell that include providing structure and controlling chemical reactions. Proteins are molecules in the cell that encode genes. Proteins carry out activities in the cell that affect traits.arrow_forwardChoose one human multifactorial condition and describe it in detail.

Population geneticsb. Molecular biologyc. Comparative anatomy and embryologyEvolution is one of the major unifying concepts of modern biology. Explain the mechanisms that lead to evolutionary change. Describe how scientists use each of the following as evidence for evolution.• Bacterial resistance to antibiotics• Comparative biochemistry• The fossil recordsarrow_forwardWrite true if the statement is correct. If false, change the underlined word or phrase to make the statement true.arrow_forwardNOTE: ANSWER THE 3 SUBQUESTIONS. From the choices below, select which perfectly describes the situation: CHOICES a. Capacity for Precise Self-Replication and Self-Assembly b. Defined Functions for Each of their Components and Regulated Interactions Among Them c. Systems for Extracting, Transforming and Using Energy from the Environment d. Mechanism for Sensing and Responding to Alterations in their Surroundings e. A High Degree of Complexity and Microscopic Organization f. A History of Evolution Change SITUATIONS: 1.1. Even though organisms tend to be of same species, they exhibit different feature or characteristic which is brought about by their adaptation at a certain condition; thus, evolution is dependent on the specific environmental condition the organisms are living in, as well as can be specific to a particular species. Which among the distinguishing characteristics of living organisms explains this? 1.2. All organisms experience environmental pressure which threatens their…arrow_forward
- In addition to physical traits, gene sequences can be used when comparing related species. Instead of looking for the presence or absence of a specific gene, you would look at the percent similarity between the same gene in two or more species. Therefore, it is important to select a gene that contains a similar DNA gene sequence in each of the species being compared. Certain genes are involved in processes that are required for basic cellular function. As these processes are critical to cell function, the genes that regulate them are highly conserved, meaning that they have remained essentially unchanged over time. Glycolysis is one such process that is critical for cellular metabolism. Glycolysis involves converting glucose into pyruvate in order to generate ATP, the energy currency of the cell. Because glycolysis is an essential process for all species, the genes involved are therefore highly conserved. You will be looking at similarities among different taxa of the highly conserved…arrow_forwardIn the new paradigm, biology is a science based on three levels of molecular information: Biology is a science of information: starting from discovery of DNA and the genetic code, now biologists study how that information is stored, how it is used, and how it evolves. Biologists can take advantage of the same molecular tools to analyze different biological systems, comparing and contrasting the details of information storage and processing that information. Level 1. genetic information is encoded in DNA. Level 2. Biological information is embodied in proteins. What is Level 3? _______________________________ Give your explanation. ____________________________________arrow_forward. Structure and function is a central theme to the study of biology. Each major group of organisms has evolved its own body part “tool kit" – a collection of structures that have evolved in ways that make specific functions possible. From capturing food to digesting it, and from reproducing to breathing, organisms use structures that have evolved into different forms as species have adapted to life in different environments. The structure of wings, for example enable birds and insects to fly. The structures of legs enable horses to gallop and kangaroos to hop. a. Think about your own teeth. What kinds of foods do you think human teeth are suited for? b. List at least three ways the structure of human teeth serves the function of eating these food materials. c. Now, finally apply the theme of structure and function to something you're very familiar with - your hands. List out all the ways you can think of that the structure of your hands serve the function of your hands.arrow_forward
- The Scientific Revolution, starting with Copernicus in the 15th century and ending with Newton in the early 18th century, would have profound impact as it heralded the birth of modern science and the scientific method. The result was important advances in the basic sciences as well as medicine itself in Europe during this period (15th through the 18th century) that would make possible the prevention and cure of diseases. Define the Scientific Method and discuss how it relates to advances in medicine ((hint: microscopy, anatomy, chemistry and the study of specific diseases).arrow_forwardPlease help with the following: Prior to approximately 12 KYA, humans were hunter-gatherers and relied on wild plants and animals for subsistence. This means that their conscious manipulation of the genomes and gene pools of other organisms was essentially non-existent. 12KYA signaled the beginning of plant and animal domestication efforts. A. Two true statements; one false statement B. Two false statements; one true statement C. All True statements D. All False statements E. None of the abovearrow_forward1a.
