The following will ensure laboratory safety during an experiment;
1) Using tongs to handle a hot beaker: This prevents direct contact with the hot beaker and avoids burns
5) Turning off the hot plate after use: If the hot plate is left on, it could injure anyone who might touch it accidentally
Answer:
Exocytosis
Explanation:
Some molecules are simply too big to move via a transport protein or the plasma membrane. To carry these macromolecules in or out of the cell, cells employ two more active transport pathways. Macromolecules or big particles are transported across the plasma membrane via Vesicles transport or other cytoplasmic structures. They are of two types, Endocytosis and Exocytosis
From the given information, Exocytosis is the right answer.
It is the process of vesicles combining with the plasma membrane thereby releasing their contents to the exterior of the cell. When a cell creates components for export, such as proteins, or when it gets rid of a waste product or a toxin, exocytosis occurs. Exocytosis is the process by which newly generated membrane proteins and membrane lipids are transported on top of the plasma membrane.
You have 1 mol of silicon atoms. Therefore you have its atomic mass in grams. The answer is 28.055 g of silicon.
