A plant cell has a cell wall and an animal cell doesn’t. The cell wall keeps it from moving and protects the plant.
Answer:
this one`s been up for debate for awhile now.
1. it depends on the organism
learning about an organism could be considered 'easier' to study in different ways. for example, if you are studying marine life, you will most likely have to keep it in a water habitat to watch it alive. If you are studying a land species, then watching from it`s natural habitat will give you more accurate results. sometimes the environment can affect an organisms internal systems more than you may think. this leads into my second point.
2. it depends on what you are trying to study
if you are trying to learn about the mating process, seasonal activity, migration, or external behavior, then monitoring it from it`s natural habitat or an area that is a close copy is your best option. but if you are looking into studying internal organs/systems or cells, then in <em>most</em> cases, the organism will need to be taken out of its natural habitat. only in very careful situations is it left in a habitat during examination.

The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. Hope it helps
Globular clusters is a type of star system where the stars are tightly bounded by gravity.
<h3>What is a star system?</h3>
A star system can be defined as small number of stars that orbit around each other and are bound by gravitational force of attraction.
It is also called a stellar system.
Globular clusters is a type of star system with the following features;
- It is composed of hundreds or thousands of low-metal old stars.
- Stars are similar to those in the spiral galaxy
- Stars are tightly bound by gravity.
Hence, globular clusters is a type of star system.
