The cell membrane is comparable to a security guard. It regulates the substances that enter and exit cells, allowing necessary substances in and keeping harmful ones out.
The organelle that can be compared to a security guard who determines who is allowed to enter and exit a building is the cell membrane. The cell membrane, also known as the plasma membrane, is a biological structure that separates the interior of cells from the outside environment. It functions similarly to a security gatekeeper, regulating the transport of substances in and out of cells. For example, it allows useful substances such as glucose and amino acids to enter the cell while preventing harmful substances from entering. In this way, the cell membrane ensures the safety and functionality of the cell, acting as its security guard.

Answer;
B. Group: 3rd and 4th hours, with values under the true density. Group: 1st, 2nd, 5th, and 6th hours, with values over the true density.
Explanation;
Accuracy refers to the closeness of a measured value to a standard or known value.
Accuracy is a qualitative term referring to whether there is agreement between a measurement made on an object and its true (target or reference) value.
