Answer: This is called Monohybrid Experiment 
Explanation: Monohybrid Cross
P Generation	TT     *  	tt
  	Tall plants    	Dwarf plants
F1 Generation  
 T	T
t	Tt	Tt
t	Tt	Tt
In F1 generation;
There are 100% Tt Genotype and 100% Tall plant Phenotype
F2 Generation 
F1  	*  	F1
( Tt  	*  	Tt )
 T	t
T	TT	Tt
t	Tt	tt
In F2 Generation;
Genotype
There are 25% TT (homozygous dominant, tall plants).
50% Tt (heterozygous tall plants), and
25% tt (homozygous recessive dwarf plants).
This is how dwarf characteristics reappear in the second generation.
The Phenotype of F2 generation is 3:1  (Tall : Dwarf)
I have attached a document to this answer to facilitate effective understanding if there is anormalities in arrangement the Punnet Square.
 
        
             
        
        
        
There are two types of neurons in our legs: motor neuron and sensory neuron. These send and receive messages to and from each other and the brain.  
After Ed's accident, he can't move his injured leg since the motor neuron is dysfunctional. The sensory neuron is functional so he can feel his limbs but can't move them since when the sensory neuron sends a message to the motor neuron, it isn't able to deliver the message to the brain to make the leg move. This is why he can still feel his limbs but is not able to move them.  
        
             
        
        
        
Answer: I think it's c im sorry if it's wrong
Explanation: I took the test on Monday
 
        
                    
             
        
        
        
3) C. Stomata, as I explained in my previous answer.
4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips
5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).
