Question

Which of the following is not a core concept of biology, as advocated by "Vision and Change"? a. Evolution b. Information flow, cxchange, and storage c. Structure and function d. Taxonomy Pathways and transformation of energy and matter

Short answer

The option that is not a core concept of biology, as advocated by 'Vision and Change', is Taxonomy.

Step-by-step solution

Understand Core Concepts

‘Vision and Change’ is a program that advocates for the core concepts and competencies of undergraduate biology education. This program’s core biological concepts include: Evolution, Information flow, exchange, and storage, Structure and function, and Pathways and transformation of energy and matter.

Refer the Options to Concepts

Now refer each of the given options to the core concepts of 'Vision and Change'. It can be observed that all the options except 'Taxonomy' are mentioned in the core concepts.

Conclusion

Since Taxonomy is not mentioned as a core concept by the ‘Vision and Change’ program, it can be concluded that out of the given options 'Taxonomy' is not a core concept of biology as advocated by 'Vision and Change'.

Key concepts

Vision and Change program

The "Vision and Change" program is an influential initiative aimed at transforming undergraduate biology education. It focuses on enhancing the way biology is taught in colleges and universities by promoting key concepts and competencies that reflect the true nature of the subject. The main goal is to better prepare students for more advanced studies and careers in the sciences. This program identifies core concepts of biological education, revealing a comprehensive framework to help students understand biology in a more integrative manner.

• Evolution
• Information flow, exchange, and storage
• Structure and function
• Pathways and transformation of energy and matter

These concepts serve as guiding principles to help students develop a deeper understanding of life sciences. By emphasizing these foundational themes, the "Vision and Change" program ensures that students can think critically and integrate knowledge across various aspects of biology.

evolution

Evolution is a vital core concept in biology, encompassing the processes that have led to the diversity of life on Earth. It explains how species adapt to their environments over time. Evolutionary theory is supported by a substantial body of evidence from various scientific disciplines, including genetics, paleontology, and ecology. Understanding evolution helps us comprehend the complexities of life and the interconnectedness of different organisms.

• Natural selection is a primary mechanism of evolution, where traits that enhance survival and reproduction become more common in populations.
• Genetic variation and mutations drive the diversity of traits upon which natural selection acts.
• Evolutionary theory provides insights into biological functions, ecosystem dynamics, and even the development of new medical treatments.

Learning about evolution equips students with the ability to explore biological challenges and innovations critically.

information flow

The concept of information flow, exchange, and storage in biology emphasizes the processes through which genetic information is transferred within and between organisms. It underpins essential biological functions like growth, reproduction, and immunity.
In cellular biology, the concept is exemplified by the central dogma, which describes

• DNA replication: where information is copied.
• Transcription: where DNA is converted into RNA.
• Translation: where RNA is used to produce proteins.

Information flow plays a crucial role in heredity and evolution, shaping how traits are passed on and varied among generations. Understanding these processes provides crucial insights into methods such as CRISPR and genetic engineering.

structure and function

In biology, the concept of structure and function is pivotal in understanding how the forms of biological entities relate to their purposes. This core concept bridges the gap between appearance and operation, demonstrating how the structure of molecules, cells, and organs are intricately designed to fulfill specific roles.

• Proteins have unique shapes that determine their function in catalyzing reactions or signaling within cells.
• The structure of the heart, with its chambers and valves, aligns perfectly with its function of pumping blood throughout the body.
• At the cellular level, the structure of membranes allows selective transport, maintaining cellular homeostasis.

By examining biological structures, scientists can infer function, which is key in areas such as biomedical research and understanding how diseases affect organisms.

pathways and transformation of energy and matter

This concept involves understanding how energy and matter cycle through biological systems, sustaining life processes. Fundamental to this idea is the principle of energy flow, starting from the sun and moving through an ecosystem via producers and consumers.
In plants, photosynthesis captures solar energy, converting it into chemical energy in the form of glucose.

• This stored energy is then transferred through food chains as organisms consume plants and are themselves consumed.
• Cellular respiration releases energy from glucose, facilitating biological work within cells.
• Matter cycles, as seen with carbon and nitrogen, demonstrate how nutrients are reused and recycled in ecosystems, maintaining balance.

By understanding these pathways, students can appreciate the interconnectedness of ecological networks and address challenges related to sustainability and energy resource management.
