Answer:
Scientists would most likely want to forecast space weather in order to know if it is safe for not only to lift off into outer space, but to be able to help astronauts in any case of emergency if something were to happen in the future.
Such as debris of small rocks that could pass by, so then astronauts would have to stay in the shuttle. To be protected from it.
In any case, scientists want to forecast the weather in outer space in order to protect astronauts, from any incoming dangers.
Water pollution. It runs into creeks and pollutes the water and ruins the quality.
Answer;
-Endocytosis
Explanation;
-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell
-Phagocytosis: endocytosis of large solid particles (“cell eating”)
-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)
-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell
-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
The answer is:
The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.
