Answer:
d. BB
Explanation: The only possible phenotype would be BB because if you draw a Punnett square you see that you get BB, BB, BB, and BB so that is the only posssible genotype.
 
        
             
        
        
        
Let us consider each statement separately. A zygote is the result of the fusion of two gametes (reproductive cells) and thus only appears in sexual reproduction. For the same reason, E) is wrong; meiosis is a step in the making of gametes and again, a plant that reproduces asexually does not produce gametes. B) is also wrong since (healthy) members of the same species have the same number of chromosomes. The leaf cells of the daughter plant will have 24 chromosomes. The only case where this would not hold, is the case of sexual reproduction, where the gametes of the new organism have half the chromosomes of the ancestor organisms. Hence, C and D are correct. We have already justified D. As far as C is concerned, in asexual reproduction we have that every organism passes his whole genome to his offspring and this creates a lot of clones next to each other. Every plant in a garden of a species that reproduces asexually may be genetically identical and some biologists consider them for that reason as the same organism!
        
                    
             
        
        
        
A reef is a ridge of a rock of any type of land that extends some distance just under the surface of the water. A coral reef is a lot of calcium carbonate that is also made up of living creatures. A coral reef is created when a small amount of dead coral turns into calcium carbonate. This process is very slow. The famous reefs are the Great barrier Reef of Austria and Belize and Cayman Islands.
Wave actions are usually not a problem due to hard coral reefs. The reef reduces a wave energy. But sometimes waves can break off or flatten large portions of coral reefs, forming grooves in once circular reef. The higher areas between the grooves are known as buttresses and may grow together at the top producing arches. 
 Answer:  Landform that develops on coral reefs as a result of wave action are Arches.  
        
             
        
        
        
Answer:
The nervous system is the part of an animal's body that coordinates its behavior and transmits signals between different body areas.
