Virtual Lab 5: Ecosystem simulator
Read the Overview and launch this ecolosystem simulator. Familiarize yourself with the simulator interface. Notice that you can command which species are present in your environment ab initio and what the diets of each species are. The types of species possible in the plan are Plants ( A. B. C ) . Herbivores ( A. B. C ) . Omnivores ( A. B ) and one top Predator. You can command the diet of each by bespeaking what they feed on. By puting up different get downing constellations you can look into the development of this fake ecological system. A. In a twosome of sentences describe what happens when you start with merely two ( A & A ; B ) and so all three works species present.

B. Describe how many herbivores and omnivores you added ( and what they eat ) in order to make an ecosystem in which all three works species can coexist. ( if you can non carry through the endurance of Plant C depict your best constellation. Describe your ecologies by placing the species present and their diet. for case: Omnivore A chows Herbivore A. Herbivore A chow works A and works B. Herbivore B eats works A. All workss present.

C. If you can carry through portion B. see if you can acquire all of the species to coexist. ( restrict your clip on this full experiment to 90 proceedingss )

D. If we assume that this simulation is a sensible simplism of a typical ecosystems nutrient web what does it state us about biodiversity and ecology- are they robust or fragile? In general is an ecosystem’s biodiversity preserved as it responds to alter? Virtual Lab 6: Development: Sexual activity and the Single Guppy

This simulation follows a set of existent life experiments in development and natural choice. Familiarize yourself with the interface. rainbow fishs. guppy marauders. and the experiment. Use an “even mix” of the different guppy colour types to get down. Run three experiments one with each of the combination of marauders. Each experiment should run for five or more coevalss. Type your solutions in bold face text. • State the per centum that each colour type makes up in your guppy population both before and after you have let five coevalss base on balls. With each experiment province a decision that is consistent with your observation. 1. Rivulus merely

2. Rivulus and Acara
3. Rivulus. Acara and Cichlids.

• What two choice force per unit areas are operative?

Virtual Lab 7: Anatomy and Dissections
A. Dissections
1. Earthworm
A. Identify points 1 & A ; 2 on the external dorsal ( back side ) surface of the worm. B. Identify points 3. 4. & A ; 5 on the external ventral ( belly side ) of surface of the worm. C. Identify point 2 in the image of the worm’s internal morphology w/o the digestive piece of land. D. Describe sexual reproduction in worms.

2. Fetal Hog
A. Use the Anatomical References usher. To what part of the organic structure does dorsal. ventral. anterior. and posterior refer to? B. Investigate the Nervous system. The hog is similar to the human in many ways. Name four big parts ( lobes ) of the encephalon and bespeak where they are located and what maps they have in worlds.

B. Comparative Hominid Anatomy
• Compare the the skull dramatis personaes of a Pan troglodytes. Australopithicus. Homo erectus. Neandertal man. and modern Homo sapiens. Be certain to utilize the sidelong position. • Describe characteristics that are common and different between the cranial construction of these animals. What patterns do you see? • Describe the basic timeline and sequence of development for the animals listed above. Be expressed.

Virtual Lab 8: Human Impact

A. Water footmarks
• Describe the H2O crisis. How is it impacting adult females and kids globally? What is go oning with the Ogalala ( be specific ) ? • Describe what the H2O footmark is and how it is estimated. • Report the two or more estimations of your H2O footmark ( and the reckoner ( s ) that you used ) . • Describe three ways that you ( or your society ) could cut down your H2O footmark.

B. Carbon footmarks
• Describe what has happened to atmospheric CO2 over the last 100. 000 old ages and how this is thought to be impacting the clime. • Describe what the C footmark is and how it is estimated. • Report two or more estimations of your C footmark ( and the reckoner ( s ) that you used ) . • Describe two ways that you ( or your society ) could cut down your C footmark. • Describe two ways that you would recommend we adapt society-wide in order to cut down our national C footmark. Be explcit.
