children? What is the genetic construction of a Pit Bull? Can fighting dogs be rehabilitated? What is the history of Pit Bulls? Do Pit Bulls actually have a “locking” jaw mechanism? What makes Pit Bulls so potentially dangerous? Is breed-specific legislation justifiable‚ right or fair? Why do Pit Bulls often comprise the majority of animals in shelters? Can bad behavior in Pit Bulls be wholly attributed to the environment in which they are raised? Can/do Pit bulls make good pets

UNIT 74 Support individuals with specific communication needs 1 Understand specific communication needs and factors affecting them 1.1 Explain the importance of meeting an individual’s communication needs It is therefore important for the carer to be aware of the individuals preferred method of communication and also to support the individual to use their preferred method. Individuals have the right to communicate through their chosen method and their choice should be acknowledged and respected

enthalpy equation qwater = m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. The water has absorbed the heat of the metal. So‚ qwater = qmetal m=mass of water= density x volume = 1 x 26 = 26 grams ΔT = T(mix) – T(water) = 38.9 – 25.3 = 13.6 q(water) =26 x 13.6 x 4.18 q(water) = 1478 Joules 2. Using the formula qmetal = m × c × ΔT‚ calculate the specific heat of the metal. Use the data from your experiment for

Would you enact a ban on cars because someone was killed in an auto accident? Well this is precisely the type of logic which has been used to come up with breed specific legislation banning pit-bulls calling them a dangerous breed of dog. These animals are not to blame for the way in which they are bred‚ raised and trained any more than an automobile is responsible for the way it is designed‚ manufactured and driven. We should not allow legislation to pass which outlaws an entire breed of dog due

range of breeds and‚ often‚ a mixed-breed dog. People think they are a very dangerous breed of dog. Because of this‚ some areas do not allow pit bulls and breeds like them. I do not believe pit bulls should be banned or technical words are breed specific legislation. The National Caine Temperament Testing Association tested 122 breeds of dog and Pit bulls placed the 4th highest with 95% passing rate. With this fact it can only be how the dog is raised. People who own pit bulls should be obligated
