AP Biology Reading GuideFred and Theresa HoltzclawChapter 33: InvertebratesName Period Chapter 33: InvertebratesChapters 31, 32, and 33 should be considered as a single unit, and you should try to put all of them together in a single conceptual framework. Due to the scope of our course, you are likely to see more general questions on individual phyla. For each of the phyla that we highlight in the questions that follow, try to know the characters that are unique to that group, and focus on the evolution of various systems. So they have time to teach the more difficult molecular concepts, many teachers choose to have students learn this unit on their own. Our goal here is to focus your time and energy on what we have seen to be commonly asked information.
At the end of this Reading Guide chapter, you will find a chart that may help you to organize this knowledge.Concept 33.1 Sponges are basal animals that lack true tissues 1.You may have learned in an earlier course that sponges are in the phylum Porifera. This group is now known to be polyphyletic, and all sponges belong to either phylum Calcarea or phylum Silicea.
They are the simplest animals and lack true tissues. Chapter 32 – An Introduction to Animal DiversityAll animals share a common ancestor, sponges are basal animals, eumetazoa is a clade of animals with true tissues, most animal phyla belong to the clade bilateria, and vertebrates and some other phyla belongAnimals share a unique homeobox-containing family of genes, known as the Hox genes, suggesting that this gene family evolved in the eukaryote lineage that gave rise to animals. Hox genes play important roles in the development of animal embryos, controlling the expression of dozens or even hundreds of other genes. Hox genes can thus control cell division and differentiation producing different morphological features of animals.Some calculations based on molecular clocks estimate that the ancestors of animals diverged from the ancestors of fungi as far back as 1.5 billion years ago.The Cambrian explosion is a period where animal diversification appears to have accelerated dramatically between 542 and 525 million years ago. The first hypothesis is that new predator-prey relationships that emerged in the Cambrian period generated diversity through natural selection. The second hypothesis focuses on the rise in athmospheric oxygen that preceded the Cambrian explosion. The third hypothesis holds that the evolution of the Hox gene complex provided the development flexibility that resulted in variations in morphology.XxTtYyRadial symmetry is the form found in a flowerpot while bilateral symmetry is a.
InvertebratesJellyfishThe Jellyfish are truly a wonder of nature. They have always been objects of deep observation and admiration. Not to mention the fact, that they are also considered in great awe, fear and even repulsion by some folks. The repulsion and fear have originated from the fact that these creatures can be quite beautiful to behold, but extremely painful when stung by them.These marine creatures are classified under the group of Cnidarians.
They typically have a soft jelly like consistency to their body, prompting the people to call them as Jellyfish.There are numerous surprises in store, when we deal with Jellyfishes. The first and foremost of the surprise is the vast reservoir of chemical factories, inside the tiny body. Though this creature does not have a vertebral column, a proper demarcation of body and head, and not even a brain, yet this Jellyfish is seen to possess numerous different chemicals, some of which are extremely toxic and poisonous too.Next in store for the observer or the scientist is the next surprise, which is the fluorescent quality of these creatures. The Jellyfish possess a chemical protein inside their body fluid, called as aequorin, which was derived from the species of Jellyfish called as Aequorea Victoria. The GFP or the green fluorescent protein was derived from this protein.
Both these proteins have a property of photo luminescence, which means lighting up in the dark, and also the property of fluorescence.An Overview of AnatomyLaszlo Vass, Ed.D. Version 42-0001-00-01Lab RepoRt assistantThis document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.obseRvationsWhat is the purpose of this exercise?Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.Exercise 1: Anatomical PositionQuestionA.

An Interconnected EconomyB.
Globalization and the DemocracyThe expansion of trade, global interconnection and privatization of government enterprises that gained momentum with the dismantling of Soviet-style socialist economies in the 1990s cooled abruptly in the wake of 9/11.Growth in India and China resumed quickly, and the large population marked them as future world economic powers. OPECs manipulation of the oil prices, along with the political instability in the Middle-East caused oil prices to soar between 1973 and 1985. The increase caused ambitious economic programs in Russia, Saudi Arabia and in some areas of the Persian Gulf, but fell quickly in 2008.Regional trade associations came into being to promote growth, reduce the economic vulnerability of member states and balance economic dominance; the Economic Union was the most successful.The euro competed with the U.S. Dollar, but unequal levels of development among members became a source of friction in 2009 as the world economic downturn devastated stock markets and increased unemployment.Despite the expansion of EU, NAFTA governed the world’s largest free trade zone and eliminating tariffs among the US, Canada and Mexico.The SCO, formed with China, Russia and 4 former Soviet Central Asian republics pursued common security interests, such as combating separists movements and terrorism. Efforts to rescue countries.
He stated, “ ‘Progress’ is merely a modern idea, that is, a false ideal. The European of today is vastly inferior in value to the European of the Renaissance: further development is altogether not according to any necessity in the direction of elevation, enhancement, or strength.2. A.) Paul Verlaine, Arthur Rimbaud, Charles Baudelaire, Stephane Mallarme, & Maurice Maeterlinck.B.) To find a language that embraced the mystical, the erotic, and the ineffable world of the senses.3. A faun is part man, part beast. A nymph is a beautiful forest maiden. They have an erotic encounter.4. They preserved the romantic fascination with nature and the Realist preoccupation with daily life.
They idealized nature. They were interested in sensation and the sensory experience.
They tried to record an instantaneous vision of their world, sacrificing the details of perceived objects in order to capture the effects of light and atmosphere. Some painted canvases that offered a glimpse into the pleasures of 19th century urban life.5. Bergson viewed life as a vital impulse that evolved creatively, much like a work of art.
True to Bergson’s theory of duration, experience becomes a stream of sensations in which past and present merge.6. Reliquaries, masks, and freestanding sculptures were among the power objects used to channel the spirits of ancestors, celebrate rites of passage, and ensure the well-being of the.AP Biology, Chapter 33 Invertebrates by cladeSUMMARYINTRODUCTIONPARAZOAIntroductionPhylum Porifera: Sponges are sessile with porous bodies and choanocytes1.

Keima UdokaIntroduction: Millions of animal species exist, many of which remain undiscovered. Animals exist all over the earth, but the majority are of the aquatic species. Studies of invertebrates and invertebrates on land and in water allow biologists to understand the animal kingdom and its diverse members.THEME#1: The innumerable organisms of the Animal Kingdom demonstrate the biological theme that diversity and unity are the dual faces of life on earth.
