I think it is sodium good luck! sorry if I’m wrong
Viruses are not considered "alive" because they lack many of the properties that scientists associate with living organisms. Primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell- division approach to replication.
Answer:
1. As the cell size increases, the ratio of surface area to volume DECREASES
2. It depends on the unit of the ratio 6:1. If it is in cm−1, then it means that it is similar to a cell of size 1 cm^3, which is normally too big to get materials from the surface
.
3. A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly. So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1
HOPE THIS HELPS!!!

Explanation:
Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
Answer:
False
Explanation:
A virus (which is a pathogen) has a lot of antigens on its surface, so they can't be used interchangeably.
