Matter on Earth is generally found in one of three different states: solid, liquid, or gas. Another common state of matter that is much more rare on earth is plasma. The state of matter that a substance has depends on the arrangement of the particles, the attractions between particles, and the amount of energy the particles possess. Assignment...Only 1 question this week, be complete and detailed.
1. Using water as an example, in one paragraph describe the list the three phases of matter that water exhibits, how it changes from one phase to the other and whether or not the mass of the matter changes as it goes from phase to phase. Assignment...In the comment section answer the following...
Some organisms have favorable traits that are well-suited to their immediate environment. Organisms with this advantage are more likely to thrive, reproduce, and pass their traits to future generations than organisms without those favorable traits. This process is known as natural selection. Watch the video below and notice a few examples describing natural selection. This theory suggests that all organisms are related to each other if you go back far enough in time. After watching the video please see the assignment below... Assignment....to be completed in the comment section....
The ultimate source of energy for all ecosystems is the Sun. Only producers can convert solar energy into food energy. Therefore, all other organisms depend on producers for their energy needs.

An example of a Mutualism Symbiotic Relationship found in nature...List the two species and include the benefit received by both species. (5 points) 3. An example of a Paraistism Symbiotic Relationship found in nature...List the two species and include the benefit received by one species and the negative effect received by the other species. (5 points) Standard OH Grade 6-8, Science Standard Life Sciences C Explain how energy entering the ecosystems as sunlight supports the life of organisms through photosynthesis and the transfer of energy through the interactions of organisms and the environment. Life is very diverse and living things come in all shapes and sizes. For this week research different types of living things and write about them.
Step by step directions:
Features of an offspring that result from genes passed on by parents are called traits
Behavior is usually determined partially by heredity and partially by experience. Behaviors determined by genetics are inherited. Behaviors determined by experience are learned. Assignment...
Reproduction is the process through which organisms create offspring that contain all or part of the parents' genetic material. The ability to reproduce is necessary for the survival of a species.
