Chapter 40.2, Problem 3CC
Summary Introduction
To explain: The reason behind the 24-hour rhythms of cyanobacteria and humans that reflect convergent evolution.
Concept introduction:
Circadian rhythm is a biological process that displays an endogenous and entrains able oscillation of about 24 hours. A circadian rhythm is also defined as a set of physiological changes that occur roughly every twenty four hours. A circadian rhythm comes under intrinsic to the body.

You are examining an organism you believe to be an animal. Which of the following would NOT support your
hypothesis?
O A The organism appears to be heterotrophic.
O B The organism appears to be multicellular.
O C The organism appears to be motile.
O D The organism appears to have cell walls.
O E All animals, including sponges, have development directed by Hox genes.
WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.
1) Name and give a brief account of the theory that explains the evolution of Eukaryotic cells from Prokaryotic cells.
2) Explain the reactions that occur to form polysaccharides, using starch as an example.
3) What do enzymes do?
What are their main structural features?
Give an example of a biological enzyme.
4) Describe the structure of fats and lipids.
Why are some solid at room temperature whereas others, particularly from plants, are liquid?
Briefly describe the structure of an animal cell.
What are the main differences between animal and plant cells?
Briefly outline the steps involved in the synthesis of ATP in eukaryotic cells

A few scientists think that peroxisomes also have an endosymbiotic evolutionary origin, although most scientists disagree with this hypothesis. Which of the following hypothetical discoveries would provide support for the hypothesis that peroxisomes evolved from bacteria? Discovering that eukaryotic cells cannot live without peroxisomes. All of these hypothetical discoveries would provide support for the hypothesis that peroxisomes have an endosymbiotic evolutionary origin. Identifying the presence of DNA within peroxisomes. Determining that the majority of proteins in peroxisomes have eukaryotic origin.arrow_forwardYou have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3.

- Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related? O A. Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous. O B. All prokaryotes and eukaryotes use DNA to carry their genetic information. OC. Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease. O D. Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other. O E. The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. «< Question 5 of 120 A Moving to another question will save this response. 11:51 AM 12/16/202 End F10 pgUP F11 PgDn F12 Home PrtScn F8 DII F5 F7 F6 F3 F4 F2 & #3 2$ 7 8 9.…arrow_forwardWhich of the following steps has not yet been accomplished byscientists studying the origin of life?(A) synthesis of small RNA polymers by ribozymes(B) formation of molecular aggregates with selectivelypermeable membranes(C) formation of protocells that use DNA to direct thepolymerization of amino acids(D) abiotic synthesis of organic moleculesarrow_forwardThe oxygen revolution changed Earth’s environmentdramatically.

- Considering the evolution of species, could a gene that is conserved from yeast to humans have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.arrow_forwardImagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?arrow_forwardEVOLUTION CONNECTION In 1847, the German biologistChristian Bergmann noted that mammals and birds livingat higher latitudes (farther from the equator) are on averagelarger and bulkier than related species found at lower latitudes.Suggest an evolutionary hypothesis to explain this observationarrow_forward
