Answer:
The movement is called revolution when a body travels around another body in space.
Explanation:
The movement is called revolution when a body travels around another body in space. It is different from rotation which is a phenomenon where a body revolves around its own axis. For example, we can assume the motion of earth as revolution when it travels around the sun and completes one complete revolution in one year, on the other hand when it moves around its own axis the day and night transformation happens. We can also take the example of moon which revolves around the earth and many other planets which revolve around the sun. So it is very easy to understand the concept of revolution.

Answer:
B) Coating of microbe to aid phagocyte recognition
Explanation:
Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.
The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.
Thus, Option-B is the correct answer.
Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells

Answer:
The difference would be that Mercury has a denser, warmer atmosphere and Earth has a not that dense and gassy atmosphere. The Earth's atmosphere also has a lot of layers while Mercury's doesn't. Those would be the reasons for them both being different. Hope this helped!
Explanation:
Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
