Summary Introduction
Introduction:
Evolution refers to the gradual change in the heritable characteristics of an organism generated over successive generations. Evolution of species gives rise to diversity among organism and the formation of new species. Sometimes, even imperfections can result in evolution. Evolution suggests that all organisms are descendants of a common ancestor.

- One of the simplest definitions of a life-form is anything with the capacity to reproduce and regulate itself. Before life began, the complex organic, or hydrocarbon-bearing, molecules that makeup RNA and DNA, the building blocks of life, must have formed. No one knows exactly how life is formed from these molecules, but many ideas have been put forward. As you enter this area, go toward the large video screen on the right and explore the “Life at the hydrothermal Vents” label deck. Some scientists theorize that life begins at deep-sea vents. Find three lines of evidence to support this claim.arrow_forwardSimple systems (of this type) of RNA , enzymes, and coenzymes have been created in the laboratory. Which probable stage of physical and chemical evolution of life is that.arrow_forwardThe properties and processes of life would be correctly described by which of the following statements? Inherited information controls the pattern of growth but not the development of an organism. Organisms process energy during the course of their lives. Life is disordered. An organism's adaptations evolve over 2 or 3 generations. Organisms are not able to regulate their internal environment.arrow_forward

- An astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins.  Which of the following conclusions about this form of life would be most justified? These organisms can produce proteins no more than 30 amino acids in length. These organisms must produce 30 different forms of mRNA Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet. Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet. These organisms cannot produce more than 30 kinds of protein.arrow_forwardA_______ is the smallest unit that can carry on all the processes of lifearrow_forwardBased on genes from mitochordrial DNA the most accepted tree of life includes three domains.

- In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a person's own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwang's group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?arrow_forwardENDOSYMBIOTIC THEORY is the evolution theory that includes a larger and one smaller cell. The larger cell act as a host and the smaller cell is called the endosymbiont that is engulfed by the host cell. The larger cell referred to eukaryotic cell and the smaller cell represent prokaryotic cell. BIOMOLECULE, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins. QUESTION: • How this theory (ENDOSYMBIOTIC THEORY) can be applies to this course subject (BIOMOLECULES)? Note: Make a connection how this theory can be applied in the course subject.arrow_forwardExplain why the following statement is incorrect. “Evolution gives species what they need in order to survive”arrow_forward
