Answer:
The order must be K2→K1, since the permanently active K1 allele (K1a) is able to propagate the signal onward even when its upstream activator K2 is inactive (K2i). The reverse order would have resulted in a failure to signal (K1a→K2i), since the permanently active K1a kinase would be attempting to activate a dead K2i kinase.
Explanation:
- You characterize a double mutant cell that contains K2 with type I mutation and K1 with type II
mutation. 
- You observe that the response is seen even when no extracellular signal is provided. 
- In the normal pathway, i f K1 activat es K2, we expect t his combinat ion of two m utants to show no  response with or without ext racell ular signal. This is because no matt er how active K1 i s, it would be unable to  act ivate a mutant K2 that i s an activit y defi cient. If we reverse the order, K2 activating K1, the above  observati on is valid. Therefore, in the normal signaling pathway, K2 activates K1.
 
        
             
        
        
        
1. The plant should not have leaves. To prevent transpiration from taking place 
2. Plant should be well watered. Plants need water
3. Put some Vaseline to seal open gaps. This prevents water evaporation 
Unfortunately I don't have the 4th one :/
        
             
        
        
        
Answer:
Inter-rater agreement
Explanation:
 The extent to which two or more raters (or observers, coders, examiners) agree is termed as Inter-rater agreement. It addresses the issue of consistency of the implementation of a rating system. 
A high inter-rater agreement value refer to a high degree of agreement between two examiners, vice-versa
