Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

NRES 102 Assignment 3 Renewable energy sources are vital to the survival of our population as well as saving the environment. Fossil Fuels are going to run out‚ it is inevitable‚ so more needs to be done to increase the utilization of renewable energy. One of our main sources of energy is oil. There is only a finite amount though‚ and even though we only started using it around the 1900s‚ it will all be gone around 2100. This gives us time to learn more about renewable sources‚ but in the end the

Representation Electron Micrograph 8.2.2 State that photosynthesis consists of the light-dependent and light-independent reactions Photosynthesis is a two-step process: 1. The light dependent reactions convert the light energy into chemical energy 2. The light independent reaction uses the chemical energy to make organic molecules Overview of Photosynthesis 8.2.3 Explain the light dependent reactions The light dependent reactions occur on the thylakoid membrane and may occur by either cyclic

birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple words‚ they cannot maintain a constant internal body temperature. 2. From the graph‚ a. Which animals could be described as true endotherms? Explain From the graph we can see that cat‚ human and platypus are true endotherms. It is because cat‚ human‚ platypus are maintaining a constant internal body temperature. Looking
