Hydrochloric acid‚ sodium chloride‚ the glass rod‚ and heat. II. Activity 8: Nerve Conduction Velocity • In this activity‚ we will be investigating action potential like in activities 1-4‚ and the nerve conduction velocity. We will test an earthworm nerve‚ frog nerve‚ and two rat nerves on the oscillator. The factors that helped determine action potential were the Bio-amplifier‚ stimulator‚ ethanol‚ and voltage. C. Materials • PhysioEx CD-Rom‚ computer‚ lab manual. D. Methods I. Activity

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

meat waste and dairy products are likely to putrefy‚ and in outdoor bins can attract vermin. Green waste should be added in moderation to avoid heating the bin. Small-scale or home systems Such systems usually use kitchen and garden waste‚ using "earthworms and other microorganisms to digest organic wastes‚ such as kitchen scraps". This includes: • All fruits and vegetables (including citrus and other "high acid" foods) • Vegetable and fruit peels and ends • Coffee grounds and filters • Tea bags

The materials used in this lab were a preserved clam‚ a dissection pan‚ bent tip probe‚ scalpel‚ specimen bag‚ pins‚ gloves‚ tools‚ paper towels‚ goggles‚ ruler‚ lab coat‚ etc. In Miss Sido`s lab prep she went over the lab packet‚ taught us how to set up for dissection by getting only the certain tools needed‚ having paper towels in the pan‚ and she taught us how to properly clean up after dissection. She performed a lab dissection demo‚ where she showed us how to properly dissect the clam and

Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests the ranks of Arthropod would swell to over 10 million species! Most people do not normally think of a clam‚ a jellyfish‚ or an earthworm as an animal. Yet all of them belong to the kingdom of animals. The science of classifying organisms is called taxonomy. In order to study living things‚ scientists classify each organism according to its: Kingdom Phylum Class Order Family Genus

On the other hand‚ (Wand BM‚ et al. 2012) describes that patients who might be exposure to complications in VAs during manipulative treatment were has an old VAs dissection history. Besides that‚ (Wand BM‚ et al. 2012) suggested abandon using manipulation therapy but notwithstanding author recommends
