![]() In fact, some trees only produce seeds when heated by fire. They clear away debris, old brush, and dying trees, leaving heartier trees better able to grow. Most forest fires and wildfires are natural.Enter the ratio as a fraction in simplest form.Ĭolor of socks white black blue brown Number of socks 6 7 5 5 The ratio of black socks to all of the socks is (answer) Use only whole numbers for the lengths of the sides of each rectangle. He wants to build a rectangular pen for his rabbits. Their period is given by: Tf1 2pi/abs(lambda1) > 5.130199 Integrating the ODE using scipy.integrate ¶ Now we will use the scipy.integrate module to integrate the ODEs. Select the animal whose absence would have the greatest negative effect on the ecosystem.(1 point) fox rabbit wolf deer Question 2 A) In an ecosystem with low biodiversity, The fox and rabbit populations are periodic as follows from further analysis. burn their bodies in the temple to become smoke.Ī) Imagine that an ecosystem contains rabbits, foxes, wolves, and deer. preserve their bodies in the afterlife.** C. pay tribute to the pharaoh in gold and grain. In order to overcome death, Egyptians believed that they needed to _.Ī.If each pair of rabbits breeds only once, how many offspring would be produced each year for 5 generations? 2. Suppose that a pair of rabbits produces six offsrping: 3 males and 3 females. tundra this is a 7th grade question and can a science teacher help me out on this please so i can study for A _ biome is a cold, dry area where the sun barely rises during the winter.Ī. A male rabbit is called a buck a female is called a doe.An older term for an adult rabbit used until the 18th century is coney (derived ultimately from the Latin cuniculus), while rabbit once referred only to the young animals.After a forest is clear-cut, desertification occurs. After an area is mined for copper, the soil is replaced and new plants are planted. Which of the following best describes an example of land reclamation?Ī. I can explain what a ratio is, and I can identify a ratio for a situation. Which best describes your understanding of ratios?Ī.x/4 = 6/7 168 0.21 28 3.43 13.Write the ratio as a fraction in simplest form. Plz help i really need 2 get this in!! 11. Where necessary, round to the nearest hundredth. The smaller arrows change the initial values one pixel at time.Īssignment: Describe what happens when both populations start at 1.Īssignment: Try to locate the equilibrium. You can fine tune your selection by using the left-right arrows above the phase plane and the up-down arrows to the right of the phase plane. You can change the initial values by clicking at the point on the phase plane that represents the new initial value. Note you may not be able to hit these points exactly. Notice that at this particular time the rabbit population is at a minimum and the fox population is between its minumum and maximum.Īssignment: For each of the phase planes below, click at two different points on the right graph in the applet above corresponding to that point. ![]() That time is indicated by a vertical bar on the right graph and, more importantly, by a large black dot on the phase plane. The rabbit and fox story illustrates an important point. In the graph above we focus on the time t = 3.2. When the fox population declined, the rabbit population increased, creating a new food supply for the foxes. You can click anyplace on the right graph to focus on a particular time. ![]() The initial values are indicated by a red square on the phase plane and along the vertical axis on the right graph. The graph on the right (with a green background) shows the fox (predator) and rabbit (prey) populations as functions of time. The graph on the left (with a blue background) shows the phase plane. The two graphs above show one model of predator-prey interaction. ![]()
