Answer: a) copy tissue
Explanation:
Tissue and cells in general get damaged, or just break down from wear and tear. So the cells divide to make up for this shortcoming, effectively replacing any broken parts with fresh new ones.
Answer:
14.0 blocks
Explanation:
Distance travelled
= 4.0 blocks + 6.0 blocks + 4.0 blocks
= 14.0 blocks
Patrice has travelled 14.0 blocks.
The order is Core,Mantle, and Lithosphere or C,B,A
Answer : The correct option is, (B) bimolecular
Explanation :
Molecularity : It is defined as the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.
The given chemical reaction are,
Step (1) : ![I_2\rightarrow 2I](https://tex.z-dn.net/?f=I_2%5Crightarrow%202I)
Step (2) : ![I+H_2\rightarrow H_2I](https://tex.z-dn.net/?f=I%2BH_2%5Crightarrow%20H_2I)
Step (3) : ![H_2I+I\rightarrow 2HI](https://tex.z-dn.net/?f=H_2I%2BI%5Crightarrow%202HI)
The number of reactants molecules taking part in the balanced equation of a reaction 2 are,
.
In this reaction, 1 'I' molecules reacts with the 1
molecule.
Total number of reactant molecule = 1 + 1 = 2
The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.
Hence, the correct option is, (B) bimolecular
