Answer:
Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%

Answer:
In interphase cell grow in size, DNA and protein synthesis takes place.
Explanation:
Interphase is the longest phase in the cell cycle and contain three sub phases and one checkpoint at the end of every checkpoint.
G₁ phase: In this phase the size of the cell increases and nearly becomes double, the raw material for DNA synthesis is synthesised e.g: mRNA and proteins(histone).
S phase: In synthesis phase replication of DNA takes place and amount of DNA become double so that it can be evenly distributed between daughter cells.
G₂ phase: In this phase cell continues to grow and synthesize proteins. cell prepare itself to move in mitotic phase so it can divide.
