Answer:
the partial of colloidal are smaller and they are not heavy whereas the partial of suspension are larger but they are heavy and less movement thus they settle down due to gravity

Answer:
Secondary research
Explanation:
Secondary research involves using already existing data, like what can be found in in books, articles, and electronic databases.
A is wrong. Primary research is the research that you do to obtain new information, as in experiments or in interviews and surveys.
B is wrong. Qualitative research is the gathering of non-numerical data.
C is wrong. Summative research is done at the end of a project to determine its success. It can also point the way to future research projects.
Answer: The correct option is B.
Explanation: There are 2 regions of the solar system.
1) Inner region: There are 4 planets which lie in this region: Mercury, Venus, Earth and Mars. The inner region planets are rocky in nature. The orbit time of these planets around the sun is short. They have 0, 1 or 2 satellites in total. There is no ring system in these planets.
2) Outer region: There are 4 planets which lie in this region: Jupiter, Saturn, Uranus and Neptune. The outer region planets are gaseous in nature. The orbit time of these planets around the sun is long. They have usually more number of satellites around them. Ring system in these planets is very common.
Hence, Mars resides in the inner region of the solar system because it has a rocky surface that one could firmly stand on.
