Answer:
organogenesis
Explanation:
Organogenesis is defined as a process in which the three germ layers differentiate further to form several organs.  
The embryonic stem cell is responsible for determining the ultimate cell type. During this process, neural system is formed and several morphological changes occur. The neural system further differentiates and develops to form neural tube and ultimately converts into brain and spinal cord. While folds and dense clusters are formed in the embryo that later form organs.  
 
        
             
        
        
        
Answer:
The correct answer is A) Have diverse cell wall compositions
Explanation:
Both bacteria and archaea comes under prokaryotes because they both lack a membrane-bound nucleus. The difference between archaea and bacteria is in their cell wall composition.
The bacterial cell wall is made up of peptidoglycan and the archeal cell wall is made up of pseudo-peptidoglycan. In bacteria, peptidoglycan contains N acetyl muramic acid and N acetyl glucosamine unit but in archaea, the N acetyl muramic unit is replaced by some other unit and the linkage of two units is also different in archaea. So the right answer is A.
 
        
                    
             
        
        
        
<span>Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.</span>
