2. cell wall is around plant cells, regulates transport in and out of cell.
3.a plant cell does not have lysosomes whereas an animal cell does
The correct answer is A. some energy is wasted as heat.
Energy is transferred between organisms through the food in a food chin. Food chain begins with producers. They make food using solar energy. They are eaten by primary consumers which are in turn eaten by secondary consumers and so on. Large amounts of energy are lost from the ecosystem when energy is transferred from one organisms to the next. In biologic systems, large amount of energy is lost as metabolic heat when the organisms are consumed by the next level.
Having a controlled group is very important.
Reason: If scientists did not have a controlled group then, they would have data for the test but they might know if the results changed or not. Scientists need a controlled group because the controlled group is like the original. They need the original group to help them know what improved or did not improve.
For example, if you were testing whether or not different types of music helps with studying, then you will need a group that does not listen to music so you can know if different types of music actually improve or just make studying worse.
Having a controlled group helps you know the difference between observations in a easier way. The controlled group is not something people should ignore. It might seem useless at first but, when a person starts to finish up their project or test then, they will understand why a controlled group is important. By the time they do, it might be too late so make sure you people use a controlled group(Especially in the Science Projects).
