Is the tendency of an organism to regulate its internal conditions to maintain good health. it is an essential characteristic that is shared by all organisms. when you are cold & when you are hot are examples of homeostasis. the basic needs of life are: – to dissolve needed substances or – for respiration or photosynthesis – to provide energy – shelter, temperature & space – a change in the environment that causes an organism to change its activity some changes take place inside an organism, which is called internal stimuli. & are examples.) others take place outside an organism; this is called external stimuli. & examples.) – the way an organism reacts to the stimulus (sneezes, moves, runs away, etc.) = living things (plants, animals, fungi, etc.) and = non-living things (rocks, water, temperature, levels of ecological organization - a group of individuals of the same species that exist together at a given place and time - all of the populations living and interacting within a specific environment - a community of organisms living and interacting with each other and their environment (includes abiotic factors) a large area dominated by characteristic plants and animals and having a particular climate, such as a rain forest, desert, or tundra the move carbon through the earth through photosynthesis, cellular respiration, decomposition and combustion. has an important role in the nitrogen cycle because it convert the nitrogen in the air to a usable form for organisms to make proteins. food chains show how energy flows in an ecosystem. they include the following roles: – makes own food from photosynthesis & provides energy to everyone in the ecosystem. – eat other organisms for food – eat plants – eat animals of another species – clean up the environment by eating dead animals – clean up the environment by breaking down dead plants and/or animals organisms complete for resources likeor the three types of symbiosis are &

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.
