Answer:
Explanation:
Scientific theory: a well established, highly reliable explanation
Scientific hypothesis: makes predictions of future events/ 
Both: based on observations of natural phenomenons/ can be tested by many researchers
 
        
                    
             
        
        
        
The answers would be:
Genotype                Phenotype
      Tt                      Tall stemmed
      tt                       Short stemmed
Genotypic ratio : 2:2 or 1:1
Phenotypic ratio: 2:2  or 1:1  
<u />
<u>You can read on to see how this was done:</u>
Tall stems (T) are dominant to short stems (t).
First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross. 
For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.
Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt. 
Now we can make our Punnett Square.
tt x Tt
<u>       t        t  </u>
<u>T |  Tt  |   Tt</u>
<u>t  |   tt  |   tt</u>
Let's list down the genotypes and phenotypic results.
Genotype        no.         Phenotype
      Tt                 2           Tall stemmed
      tt                  2           Short stemmed
So from that we can answer the other questions:
Genotypic ratio : 2:2 or 1:1
Phenotypic ratio: 2:2  or 1:1  
 
        
             
        
        
        
Answer:
b. axons  
Explanation:
The Peripheral Nervous System consists of nerves and ganglia. Nerves are nothing more than bundles of parallelly arranged nerve fibers surrounded by connective tissue. Each of these fibers is formed by an axon and the sheaths surrounding it. The ganglia, in turn, are accumulations of neurons, which usually form spherical structures, are located outside the central nervous system and are also linked by axons bridges.
 
        
             
        
        
        
The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.
 
        
                    
             
        
        
        
The other is a result of ones radiation or sun exposure
