Answer:
1. At the end of S phase- 20 pg DNA
2. At the end of G2 phase-  20 Pg DNA
Explanation:
The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.
During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.
In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.
 
 
        
             
        
        
        
Answer:182.25 joules 
Explanation:
Mass=0.18kg
Velocity=45m/s
Kinetic energy=(mass x(velocity)^2)➗2
Kinetic energy=(0.18 x 45^2) ➗ 2
Kinetic energy=(0.18x45x45) ➗ 2
Kinetic energy=364.5 ➗ 2
Kinetic energy=182.25
Kinetic energy=182.25 joules

Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions
