<span>The correct answer is option B. 0.00243 has three significant digits. This is because for a decimal number which is less than 1, all the digits except the leading zero after the decimal point are considered to be insignificant. Thus, the two zeroes after the decimal point are insignificant.Therefore, the remaining three digits i.e. 243 are the significant digits.</span>

hammer [34]

Answer:

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  

Explanation:

The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.

Structure X is not living, and structure Y is living.  - this is false, both animal and plant cells are living.

Structure X can be found in some human cells, and structure Y can be found in some plant cells.  - this is false, the opposite is true.

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  - this is true structure X is the plant cell wall, and structure Y is the cell membrane

Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
