THE PH SCALE Learning Objectives: To distinguish between acidic‚ neutral and alkaline solutions using pH values. To classify solutions of equal concentrations in terms of acid or base strength using pH values. To understand how the appropriate use of Litmus paper‚ Universal Indicator and pH meter can give an account of different degrees of accuracy in the measurement of acidity or alkalinity of substances. 1) Define what an Acid is. Give five characteristics of acids. An acid is a chemical

several cray fish and put two of them each toe to toe in a small container to see which one would dominate their opponent. One of the main behaviors we looked for was a dominance display. When using this dominance display‚ one cray fish will stand up very tall while spreading its chelae‚ the other cray fish will be submissive. We asked ourselves if the weight of the cray fish would affect the outcome of the winner or loser at all. To start off the experiment‚ we chose one really big cray fish that appeared

of first life. The Paleozoic era was the vertebrae evolution from fish to amphibians. It’s the transition from the sea to land‚ with lizards the same homogenous traits as the fish. The fish has been the very first fully preserved specimens. There are a variety of fish that evolved before they transitioned to amphibians. Its not likely that most of the reptiles today still have the same embryo phases as the common tadpole with fish features that are able to help them live underwater for long periods

species and origin based on morphological features by using DNA barcoding technique is an important application for molecular biology and genetics. In this study‚ we used special fish called bonito fish. These fishes generally live in relatively warm and hot seas and grow until they reach a length of about 30 inches. Bonito fish have a long pectoral fin and two dorsal fins. Also‚ they have a forked tail. Animal species and their origins can be detected accurately and quickly with the help of the technique

It is a tremendous mystery whether humpback whales migrate long distances by using the ability for stars navigation. Even though the reading passage shows three possible reasons for the hypothesis‚ the lecturer severely illustrates the refutations of each theories. That is‚ the reading is strongly contradicted by the speaker. First and the foremost explanation in the passage indicates that humpback whales have enough intelligent to use stars to navigate. However‚ the professor totally disagree with
