How to Find the Answer to Exercise 45 in Explorations in Basic Biology 12th Edition
Explorations in Basic Biology is a self-contained laboratory manual designed for one- or two-semester introductory biology courses for non-biology and mixed biology majors. The exercises are appropriate for three-hour laboratory sessions, but are also adaptable to a two-hour laboratory format. The manual covers various topics, such as microscopy, cell structure, enzymes, photosynthesis, genetics, evolution, ecology, and animal diversity.
One of the exercises in the manual is Exercise 45: The Human Heart. This exercise introduces the students to the structure and function of the human heart, and guides them through the dissection of a sheep heart. The exercise also includes questions that test the students' understanding of the concepts and skills learned.
One of the questions in Exercise 45 is question 45: "What is the function of the chordae tendineae?" This question refers to the thin strands of connective tissue that attach the atrioventricular valves to the papillary muscles in the ventricles. The function of the chordae tendineae is to prevent the valves from being pushed back into the atria when the ventricles contract. This ensures that blood flows in one direction through the heart.
To find the answer to this question, students can refer to Figure 45.5 in the manual, which shows a diagram of a sheep heart with labels for the chordae tendineae and other structures. Students can also consult other sources, such as textbooks, websites, or videos, that explain the anatomy and physiology of the heart. For example, one possible source is [^4^], which provides a PDF version of Explorations in Basic Biology 12th Edition that can be downloaded for free.
By using these resources, students can learn more about the human heart and its function, and be able to answer question 45 and other questions in Exercise 45.
In addition to question 45, Exercise 45 also includes questions that ask students to compare the sheep heart and the human heart, to identify the blood vessels that enter and exit the heart, to trace the pathway of blood through the heart, and to measure the heart rate and blood pressure of a human subject. These questions help students to apply their knowledge of the heart to different scenarios and contexts.
Exercise 45 is one of the many exercises in Explorations in Basic Biology 12th Edition that provide students with a hands-on experience of learning biology. By performing laboratory activities, students not only learn basic biological information but also gain experience practicing laboratory techniques. The manual also provides clear background information and directions for conducting laboratory activities, as well as guidelines for writing a scientific paper.
Explorations in Basic Biology 12th Edition is a useful resource for students who want to learn more about biology and its applications. The manual can be used as a standalone text or as a supplement to other biology texts. The manual is also suitable for instructors who want to offer their students a variety of options and activities for learning biology. 061ffe29dd
