1. What is the theory of evolution? How is it a unifying theme in biology?
The evolution theory explains the unity and diversity of life by explaining how random changes in genetic material and competition for scarce resources cause species to change gradually.
2. What is biogeography? How is it a unifying theme in ecology?
The distribution of species and ecosystems in geographic space and through geological time.
3. What is genetics? How is it a unifying theme in biology?
Genetics is the scientific study of heredity.
4. What is plate tectonics? How is it a unifying theme in earth science?
Plate tectonics is the theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle.
5. What is the Big Bang theory? How is it a unifying theme in astronomy?
The theory that the universe originated 20 billion years ago from the cataclysmic explosion of a small mass of matter at extremely high density and temperature
6. How are the following branches of science integrated, connected, and related?
• Chemistry and biology- any living thing has a chemical makeup, so the study of any living thing involves studying its chemistry.
• Physics and chemistry- one explains why an object has certain properties and the other explains how the objects move and use those properties. One is the world at a distance and the other is the world up close. You cannot have one without the other
• Physics and astronomy- physics grew from the study of our natural world in astronomy. These two re-unite to uncover origins of the universe and its evolution.
• Earth science and physics- geology looks to physics to model the earths currents and magnetic field.
• Earth science and chemistry- earth science depends on chemistry to determine what the earth is made of.

...Ronald Mathis Grand Canyon University Biology 100 July 10th 2011 The Cell Cycle Directions: Answer the following questions. Cite references as needed. Be sure to read the required Module 3 readings and view the required Web sites before completing the assignment. Cell Cycle Questions for Cell Cycle 1) . Briefly describe all phases of the cell cycle and tell what happens in each. a) Interphase: G1 phase, S phase, G2 phase Interphase: Before a cell can enter cell division, it needs to take in nutrients. All of the preparations are done during the interphase. Interphase proceeds in three stages, G1 phase, S phase, G2 phase. Cell division operates in a cycle. Therefore, interphase is preceded by previous cycle mitosis and cytokinesis (Module 3 Readings). a. G1 phase: The cell increases the supply of proteins and increases its organelles. b. S phase: Linear chromosome is replicated. c. G2 phase: Increases protein preparing to replicate. (Module 3 Readings) b) M phase: M phase is a method of indirect cell division by means of which the two daughter nuclei normally receive identical complements of the number of chromosomes of the somatic cells of the species. 2) Which phase is the shortest? Anaphase is the shortest phase of mitosis because its where the chromatids twins are all pulled apart at the centromere by the spindle fibers. 3) What is G0 (Gap 0/Resting phase)? A resting phase is when or where the cell has left the cycle...

Evolvability

...Evolvability of Animal Developmental Systems: Remarks on their Modularity and Robustness Riddhi Benani Department of Life Sciences Imperial College London, UK Supervisor: Prof Armand Leroi June 11, 2012 Abstract The ultimate aim of Evolutionary developmental biology (Evo-Devo) is to answer questions about evolvability of animal developmental systems. Evolvability or the ability to evolve is a ubiquitous property of living organisms. More specifically, it is the capacity to generate heritable, non-lethal phenotypic variation. Biologists have long recognized that evolvability of developmental programs in animals is key to their complex morphological architecture. However there is an increasing need to synthesize known facts about the developmental phenomena into mechanistic descriptions of complex systems. This ambition demands the need to understand the underlying determinants of evolvable developmental systems. I aim to review the dynamics of two systems-level phenomena: modularity and robustness and their evolutionary implications. Despite a plethora of literature, these terms have remained very ambiguous. Modularity reduces interdependence of components and confers robustness. Robustness, which is broadly understood, as the insensitivity of a biological systems functionalities to perturbations is another design principle in itself. Such robustness could enhance the potential for future evolutionary innovations. Both these properties therefore affect evolvability of a lineage...

Ap Psych Notes Module 13

...Module 13 Notes Our Divided Brain • We have known for over 100 years that despite looking alike, each side of the brain has different purposes. -Research collected over this century (about damage to the left hemisphere) proved this hemisphere was for reading, speaking, writing, reasoning, math, etc. -Around 1960, it was discovered that the right hemisphere had its own unique functions. • In 1961, patients suffering from severe epileptic seizures had their corpus callosum (which links both brain hemispheres) cut. Their seizures stopped. • Afterwards, these patients with split brains were experimented on, their personality and intellect were surprisingly unaffected. • One of these experiments involved the phrase "HE.ART" being flashed at them, with the dot being at the center of their vision (therefore "HE" went to the right brain and "ART" went to the left brain). -When the patients were asked what they saw, they said "ART" (using the left brain) but pointed to "HE" (using the right brain). [pic][pic][pic] • As evidenced by this experiment, after split-brain surgery, the two brain hemispheres have different functions. -They struggle to communicate with each other and often think different things. __________________________________________________________________ Right-Left Differences in the Intact Brain • People who have their corpus callosum intact have hemispheres that instantly communicate with...

DRAFT April 29, 2014 All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer learning. The modules generally use authentic assessment for the students to perform real-world tasks demonstrating meaningful application of essential knowledge and skills.
