Answer:
Newton's first law of motion states that there must be a cause which is a net external force for there to be any change in velocity, either a change in magnitude or direction.
Rover (or sometimes planetary rover) is a space exploration vehicle designed to move across the surface of a planet or other celestial body. Some rovers have been designed to transport members of a human spaceflight crew; others have been partially or fully autonomous robots. Rovers usually arrive at the planetary surface on a lander-style spacecraft.[1] Rovers are created to land on another planet, besides Earth, to find out information and to take samples. They can collect dust, rocks, and even take pictures. They are very useful for exploring the universe.
Answer:
PRFM
Explanation:
- Receptor-mediated endocytosis is a process where cells absorb proteins, hormones, metabolites and sometimes viruses with the formation of an invagination (inward budding of the plasma membrane). Cholera toxin, flu viruses, and diphtheria have sites that cross-react with receptor-binding sites and gain entry into cells through this pathway. <em>Pathogenic particles such as SV40, papillomavirus, and cholera toxin enter the cell via this pathway.</em>
- Phagocytosis is when a cell ingests or engulf large cells (up to 0.5 µm) or small particles to remove them from circulation. Neutrophils and Macrophages are an example of cells that phagocyte.<em> In animals, this pathway is normally limited to professional cells such as neutrophils.</em>
- Pinocytosis, also known as fluid endocytosis is the process by which liquid droplets are ingested by a cell. Potocytosis is a variation of pinocytosis, the vehicle for internalization is the caveola, an invagination formed by proteins called caveolin. <em>This pathway depends on caveolin and cavin proteins.</em>
- Macropinocytosis is the engulfment and uptake process of large amounts of fluids by the appearance of numerous irregular ruffles that eventually collapse towards the cell membrane, enveloping the content. <em>This pathway proceeds by the formation of highly ruffled regions in the plasma membrane which then collapse, resulting in fluid uptake.</em>
