 One group of reptiles, characterized by the fossil Archaeopteryx, led to the evolution of birds. The correct answer is birds
 
        
                    
             
        
        
        
The cautions that can be given to the friend include the following:
Eating foods from different sources is very advantageous because it ensures that one gets all the necessary food nutrients that are needed for proper growth and development. Getting the necessary food nutrients on the other hand will boost one's immunity and enable one to develop resistance to diseases. Restricting one's food to a limited type of food is very bad and can have fatal consequences.
        
                    
             
        
        
        
The correct answer is: A checkpoint will be activated if the spindle does not attach to a kinetochore.
Prokaryotes, do not undergo mitosis (like eukaryotes) and therefore have no need for a mitotic spindle. Prokaryotes also don’ t have checkpoints foor the regulation of cell division.
Normal eukaryotic cells (unlike cancer cells), move through the cell cycle in a regulated way in order to make sure that cells don't divide under conditions that are unfavorable for them. Information about their own internal state (nutrients, signal molecules, DNA integrity) is signal to go or not to go through the cell division. Because of that there are few checkpoints in the cell cycle at which the cell examines the signals and makes a “decision”. The major checkpoints are:
•	The G1- the first point at which it must choose, once it passes the G1 checkpoint the cell enters S phase
•	The G2-the cell checks DNA integrity and checks if replication is done well.
•	The spindle checkpoint-at the transition from metaphase to anaphase.
 
        
                    
             
        
        
        
It is more of a web because it can start in any order and move into any rock type. example being you can start as a sedimentary rock and turn into a metamorphic rock or igneous rock. a cycle starts anywhere and then goes into a specific cycle. 
hope this helps
