Initiator proteins break hydrogen bonds separating short length of DNA, AT base pairs are held together by fewer hydrogen bonds than GC pair. Thus AT pairs are easier to pull apart, At rich regions are typically found in the replication origins. Replication origins are site at which DNA is first opened.
        
             
        
        
        
A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.
        
             
        
        
        
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).
        
             
        
        
        
The greenhouse effect is the trapping of a stars warmth in the lower atmosphere of a planet by gasses in the air trapping the energy. This is similar to what actual greenhouses do, where they trap the warmth and humidity of the air inside it so plants can flourish. Farm animals produce a huge amount of the greenhouse gasses required for our planet to trap the suns warmth.
