Which of these household objects has a function most similar to the function of a cell membrane in a cell?

A. furnace
B. bookshelf
C.solar light
D. front door
I'm not quite sure, but I believe it's either A or C?

I think it was D?

The answer is D.

To determine which household object has a function most similar to the function of a cell membrane in a cell, let's first understand the functions of a cell membrane.

A cell membrane is a semipermeable barrier that surrounds all cells. It controls what enters and exits the cell, allowing essential substances to pass through while preventing harmful substances from entering. Additionally, it maintains the internal environment of the cell by regulating the transport of molecules and maintaining the proper balance of ions.

Now, let's compare the functions of the given household objects:

A. Furnace: A furnace regulates temperature inside a house but does not selectively control the exchange of substances, so it does not have a function similar to a cell membrane.

B. Bookshelf: A bookshelf is a storage unit and is not involved in regulating the exchange of substances, so it does not have a function similar to a cell membrane.

C. Solar light: Solar lights convert sunlight into electricity, but it does not control the exchange of substances like a cell membrane. So, it is not the correct answer.

D. Front door: A front door acts as a barrier to control access to a house. Although it is not semipermeable like a cell membrane, it does share the function of selectively allowing certain individuals or substances to enter and exit while restricting others. Therefore, the front door has a function most similar to a cell membrane.

In conclusion, the correct answer is D. Front door.

Nevermind, I got it.
