The roots of plants are able to self-regulate the amount of water they take in. Therefore, by adding this amount of water, Stela is insuring that the plant will have as much water as it needs to grow. 
        
                    
             
        
        
        
<span>An ice age is the amount of the Earth's water that is locked up on land in the form of glaciers.
</span>According to the scientists, an ice age occurs every 100,000 years. There are five major ice ages in the Earth's history. That are the Andean-Saharan, Huronian, Karoo Ice Age, Cryogenian, and the current Quaternary glaciation.
But, If we entered another ice age currently, it would increase the amount of locked water in the form of glaciers and hence it would have huge consequences for human civilization and the ecosystem. 
        
             
        
        
        
What do Enzymes enable cell reactions to do? proceed at normal temperature, lowers the activation energy needed for reactions to being. ... normal active energy is too high so this allows the reactions to occur at body temp.
        
             
        
        
        
The statement 'Skin cells and epithelial cells each make a different set of proteins, which determines each cell type's structure and function.' is correct. It is known as differentiation.
<h3>What is differentiation?</h3>
Differentiation refers to the cellular phenomenon for which different genes are expressed in specific cell types.
Differentiation leads to the formation of different cell types that have specific functions/roles.
Differentiation depends on gene expression pattern that influences the type and amount of proteins in a given cell.
