This distribution pattern might occur for a species whose seeds are dispersed by the wind. Species are spread out but not uniformly. Animals that live in groups, or plants whose seeds drop and grow near the parent plant, likely have this distribution pattern. An animal that keeps a territory of a specific size, so that there is a regular pattern of how individuals are spread out in a population, has this distribution pattern. 1. Random 2. Uniform 3. Clumped

There are species of freshwater fish that can live to 40 years old. They can spawn thousands of eggs per breeding season, but due to intense predation, actual numbers that survive are highly variable. Compared to other fish sharing their habitat, they are quite large. The two characteristics that suggest K-selected life strategies are Shares habitat with other fish and quite large Lives to 40 years of age and is quite large Highly variable survivability and shares habitat with other fish Spawn thousands of eggs per breeding season and highly variable survivability

When a 25.0 g sample of NaOH is added to 50.0 g of HCl in a coffee cup calorimeter, the temperature increases from 21.6°C to 28.9°C. The specific heat for this reaction is the same as that of pure water ($4.18 \frac{J}{g^oC}$). The neutralization reaction precedes as follows: HCl (aq) + NaOH (aq) --> H$_2$O (l) + NaCl (aq) Calculate the amount of heat evolved by this reaction (J).

Question content area left Part 1 The risk of a person developing heart disease is correlated with their BMI (or body mass index), which is calculated by dividing their body mass by their height (high BMIs typically mean the person is overweight). Heart disease is also related to a person's level of activity. Suppose a person's BMI is x and their physical activity is y (measured, for example, in minutes of exercise each day). Let h be a heart disease risk index (high values of h mean high risk of heart disease, low values of h mean a low risk of heart disease). h depends on x and y, that is, h=h(x,y). A simple linear model that only takes into account the effects of BMI and activity is

Question 2 (37 marks) The local taxi registration and deployment system is a paper-based system in which records are created and operated manually. The system requires the rank clerk to manually fill out a form to record returning and leaving vehicles. This demands a highly structured document management system to provide ease of reference, error checking, and efficient retrieval. You know this current system could be more efficient than a computerised system. The clerk must search many physical files before finding the correct record for each process. Keeping data in files for safety and future reference is risky because the files can be easily misplaced or destroyed. Furthermore, data retrieval is complicated, and there are significant data inconsistencies. The primary advantages of the proposed computerised system include its simplicity of operation, high data integrity, security, and speed. The clerk's workload will be reduced once the new system is implemented. 2.1 Perform a feasibility study for the proposed system. (12 marks)2.2 List and describe four potential functionalities and four system requirements for the local taxi registration and deployment system. (8 marks) 2.3 List five (5) stakeholders involved in the proposed system. (5 marks) 2.4 Using examples, describe six (6) design considerations you will consider while developing the local taxi registration and deployment system. (12 marks)
